Are you that programmer that knows all about emails? Can you dream about mail headers, write them with your eyes closed? Maybe you might be able to help me with this issue.
Let me explain ...
Workflow
The mail server receives emails
A PHP cronjob imports all emails from IMAP into the MySQL database
The user finds all emails in the Inbox in my application
Sending an email
In that same application a user can send new emails. I've handled that using the following code snippet.
$message = \Swift_Message::newInstance()
->setSubject($form->get('subject')->getData())
->setFrom('me#example.com')
->setTo($form->get('to'))
->setBody(
$this->renderView(
'MailBundle:Email:contact.html.twig',
array(
'ip' => $request->getClientIp(),
'name' => $form->get('to')->getData(),
'message' => $form->get('message')->getData()
)
)
)
;
This works fine. If the above email is submitted I create a new email in the IMAP sent folder. This, on his turn is being imported by the PHP cronjob and put in the MySQL database. It shows up in the sent folder in my application.
The issue
Now that you have a general idea of how my application works I've got some things I am not so sure about.
How can I create replies to imported emails using SwiftMailer.
How can I forward imported emails using SwiftMailer
I would like to use my application as a real mailclient and want the mail headers etc. to be correctly set.
I could of course just send an email with the original mail body and the subject prepended with "RE:". But I am not sure if that's all. I somehow suspect I need to do alot more.
In short
How would I use SwiftMailer to reply to or forward an email that is saved in a database?
Update
I implemented the reply headers as suggested in an answer to this question. I'm not sure however if this will work for the forwarding as well. I just wanna make sure that mail providers won't block my emails because the headers are incorrect.
I compared what are the differences in the header between a "first" email and a reply.
To make a reply, it seems you've to add two lines in the reply header :
In-Reply-To: [Message-ID] (with Message-ID found in the header of the first mail)
References: [Message-ID]
Obviously, you have to change the from and to in the reply email. (I think SwiftMailer creates others by itself)
To add line in email header using SwiftMailer, proceed like that :
$headers = $message->getHeaders();
$headers->addTextHeader('In-Reply-To', $previousEmail->getHeaders()->getMessageId());
This getter I put is just how I imagine your email entity.
For the forward, juste print the source of an email and check differences.
Hope it could help.
Update :
For a forward : it is exactly the same thing. I just compared the two headers.
You've to add In-Reply-To and References.
And to answer your update : You can put anything you want (string obviously) in an email header. The spam score will not grow up if you add an unknown variable in it.

I can not solve the problem of spam. I only have 7.6 / 10 on Mail-Tester.com.
I specify that I use postfix, and I need it only for the sendings.
Here is my result: https://www.mail-tester.com/web-n0z33
Mail-Tester.com tells me that the problem come from ReplyTO… But I am obliged well to use ReplyTO so that I can click "to answer" when I receives an e-mail sent since a form of contact of my Web site.
I also specify that FROM I put an email address #my-domain.fr. Because if in FROM I directly put the email address of the visitor who fills my contact form I have even worse errors with Mail-Tester.com.
And here is my PHP code:
$mailer = new Mailer();
$mailer->setFrom(contact#mondomaine.fr)
->setReplyTo('emailexemple#gmail.com')
->setTo($_GET['mail'])
->setSubject($data['subject'])
->setBody('front/specific-page/contact/contact-html', $data)
->addBodyText('front/specific-page/contact/contact-text', $data);
var_dump($mailer->send());
I use SwiftMailer with the driver at 'mail', but I created my own adapter so that's why I have this code. But it is easy to understand.
How to solve my problem? How to have a 10/10 rating with Mail-Tester.com?
Thank you very much.
I am sitting with the same problem. Currently, from what I have found on the net, you can not "fix" this. However, there are some ways to help resolve it. Here are a few options you can try, based on these references:
Ref 1
Ref 2
They both say the following:
"Wrap mail messages in HTML tags to avoid spam filters."
The FROM address must be those from the visitor who uses the contact form. How would you else respond to the email? And why even use a tool to test the spam score of an email sent with a contact form? You are the only receiver of those emails.
The 10/10 rating with Mail-Tester.com is telling you only, that Mail-Tester thinks, that your email is just fine. I would not rely too much on this tool. All email service providers have anyway own spam filters and will handle your email as they see right. For instance, if you test your email with another tool like https://www.emailchecky.com, you will mostly see other results and found errors.
Or make another test:
You can send the email also to a Gmail address and see if the email is landing in the main inbox or the spam folder instead. Gmail has the most aggressive spam filters and rules I know. If your email will pass these rules and filters you can be proud of your email.
I am wondering if there is a way to send a quick email to my leads on gmail. I want to send each message to store them in the sent folder, I know that it can be done by create each compose message but it will give me the hard work to send the emails to each user and I don't like to use BCC because when I receive the emails from the users, I will only see one message in my inbox. I want to receive each email from each user.
Example:
http://oi57.tinypic.com/ztiy5f.jpg
I don't like to receive the email like this:
http://oi60.tinypic.com/4gl11e.jpg
Is there a way to do that through on VB6, PHP, gmail or whatever it is?
Sending mail using PHP, for example. It's not as easy as it used to be.
The sending part, is trivial. Most of the time folks use the mail command, pass parameters to it, and voila.
However, with today's overachieving spam filtering via ISPs, etc. -- Chances are very good that your email might not ever get received at its intended address. It might get there, most likely will be sent to spam, and can have several hours of delay.
The best way to send email, as far as I know, is with SMTP email in PHP. PHP mail vs SMTP
I notice that a lot of websites like Facebook and GitHub allow you to reply to an email notification which then posts the reply back to the application using a unique Reply-To address. How does this work on the back-end? I searched a lot but, only found that people were using unique Reply-To addresses. That's understandable but, what do they use to receive these emails? Do these companies set up email servers? I am trying to build this using PHP.
A common method is to set unique message ID's in the outgoing email and then looking at the In-Reply-To header to see which email this was in reply to. That lets you match up your server application's messaging system to emails. For example, if you send an email that represents a help desk ticket with ID 1234, the Message-ID could be something like
ticket-1234#myserver
Then, in email clients that work nicely (I'm looking at you Android), when you hit Reply, the reply has the header In-Reply-To: ticket-1234#mysever. You can go further by adding security tokens to ensure people can't forge messages (e.g. ticket-1234-hf29e9f2gf2e9fh29f#myserver). That security token is generated on the server when you send your first message and is then confirmed in the reply.
This normally works but can cause real headaches when email clients don't behave as they should!
This is how GitLab manages emails by using an identifier in the email address itself and catching it when the user replies. Although it is not relevant to any scripting language like PHP and uses server configs, this is what backend servers do to support reply by email functionality.
You have to set up a mail server to receive mail answers.
SIEVE filters on a IMAP server could be use to make some actions when a certain filter is detected.
But you can't only use PHP to make that type of system.
I am not sure if it is in the headers or not, but I am looking for a way to tell if an email I receive is a response to an email I sent, and if so, to only grab the new text, not "quoted text"
A little background: I am creating a script that will send out emails automatically. I am creating a cron job to run at periodic intervals to check to see if there were any replies. If there were replies, I only want to grab the new stuff, and not the old stuff.
In the past, I would send out emails with the id in the subject (You have a new response [1234]), and would then check the subject for the stuff in between the [ and ]. Then I would grab all the message and store it since every web browser/email uses a different character or style for quoted-text. Some do ">" some do a horizontal rule, some do absolutely nothing.
Anyways, I am just looking for something in the email header that would indicate they are replying and what the new text might be. If it's not possible, I will just keep on doing what I am doing.
You can know if an email is the reply of another email or not by using the combination of In-Reply-To and References.
Every email has a unique ID in its header called Message-ID, according to this RFC 1, you can track the ancestors of any email.
I have checked it and it is working in all clients (Outlook, Thunderbird)
I will give an example to use.
1- In the header of the email you send for the first time, you (your mail server or you in code) send an ID (Message-ID), if you open source of the email you will see it like this in top section:
... // You (your code) send:
Message-ID: <1#your-domain-mandatory.com>
...
You just need to keep this Message-ID in your program. any subsequent reply will refer to this ID.
2- Client will reply email 1 to you. Client will send a crucial header for you to tell you for which email this reply is in addition to its own Message-ID.
... // Client(Thunderbird) send:
Message-ID: <2#your-domain-mandatory.com>
In-Reply-To: <1#your-domain-mandatory.com>
...
When you receive the second email, it will be easy for you to keep track of the previous email you have sent because the ID of mail(1) is in the In-Reply-To header of the mail(2).
3- if you want to reply back this email again inside your code, you just need to put the Message-ID of the mail(2) in In-Reply-To header and Message-ID of mail(1) and mail(2) in References header. So the client will understand the chain correctly.
... // You (your code) send:
Message-ID: <3#your-domain-mandatory.com>
In-Reply-To: <2#your-domain-mandatory.com>
References: <1#your-domain-mandatory.com> <2#your-domain-mandatory.com>
...
By this header, you are telling the client that this email is a reply to the mail(2) and the ancestors are mail(1) and mail(2).
I have worked with them and read about them and it is working, my problem now is to just get the text of the last email and not the quoted text from the replies. (we are running our own Ticketing system, we create a comment for each email)
Unfortunately, e-mail clients can essentially do whatever they want with your message, and there is no reliable standard for determining how a received message originated at the client. In addition, IMAP doesn't really have anything to do with it. E-mails can be sent a number of different ways, including webmail.
The best you can do is look for an ID number in the subject line (assuming folks don't change it, which they rarely do). You can also do what Google does... fuzzy match the reply text to e-mail you sent to that address. If it matches, consider it part of the reply. This takes great effort though.
I have a web app which needs to send emails to clients 'From' staff email addresses. What's the best way to prevent my messages from being flagged as spam?
For instance, if I own charles#gmail.com, I'd like to be able to send mail "From" that address with PHP in my App, without getting the "This message may not have been sent by...." message.
Right now I'm just using the mail() function within PHP, with Headers for the From, Return Path, and X-Mailer variables.
I'm generally pretty confused by everything I've read so far about SPF and DKIM, so I appreciate any advice. Thanks.
This is a very lengthy subject with lots of things to consider.
The most important rule is to not use HTML and to send only correct mails that people want, and that the recipients do not flag as spam theirselves.
For instance, if I own
charles#gmail.com, I'd like to be able
to send mail "From" that address with
PHP in my App, without getting the
"This message may not have been sent
by...." message.
If you own a gmail address you could just sent the messages via gmail's SMTP service, but keep in mind that gmail has a 500 email sent limit. Below is a topic describing how to use gmail's SMTP server with the popular PHPMailer.
Right now I'm just using the mail()
function within PHP, with Headers for
the From, Return Path, and X-Mailer
variables.

Just to name a few which are very cheap to use without any hassle/setup.
If instead of using the mail() function, you use an SMTP mailer such as the PEAR mailer package then you can send the mail using google's own SMTP servers. This will require you to provide the correct credentials to the google account you wish to send from. This should avoid the issue you are having.
One of the first things you need to ensure is that the email "From:..." really is from your server e.g your_mailings#yourcompany.com and it must exist and be a valid email on the server where the script works. You should try setting the sendmail user at the top of your script (assumes Linux server):
ini_set('sendmail_from', 'your_email#your_server.com');
Then you add a "Reply-To:" header and use your staff addresses perhaps and recipients will at least seem to have got an email that can be replied to. Without that you probably won't even get as far as being spam, you will get blocked on the way there.
This thread shows some of that and note the comments on PHPMailer - it is a good way to handle mailing and I have found it more successful than simple mail();
