Which email service shall I use for testing sending emails? - php

I'm coding in PHP w/ CodeIgniter and I'd like to test some of the features in my app that send emails.
For some reason, I couldn't send emails through my email account in my local server (XAMPP), and I also don't want some SPAM filter to think I'm spamming while I'm testing.
So is there any email service that I can use for testing purposes? preferably one that doesn't enforce SSL, since I have problems getting that to work on my local server.
Appreciate your help.

As long as you're not sending out dozens or hundreds of test E-Mails, use whatever your everyday E-Mail provider is (e.g. GMail). Set the SMTP server of your mailing function to point to Google's. (I think SSL is optional with GMail, but I may be wrong.)
If your mailing library doesn't support using an external SMTP server, switch to a different one. But I think CodeIgniter has you covered there.

If you just want to test the application functionality, check out Papercut. This utility simulates the sending of email without having to set up a mail server, works great!
edit: had wrong link.

I like to set up a test SMTP service on my development machine and just send to that. There are several good options listed under this question.

Sending mail from webserver to external mail server with local domain name

This is an issue I've encountered several time and haven't yet found a decent solution for:
Sending an e-mail from a webserver on e.g. "domain.com", to info#domain.com which is hosted on an external mail server e.g. Google Mail
In my case I always send from PHP over Apache and often on shared hosting, but I can imagine this is the same case on other frameworks.
These e-mails always seem to be delivered to the local mail server, even if I set the MX records on that server to point to the right external mail server.
A solution for this is to use an external SMTP server, but this isn't always easy when you're working with clients that either need to set-up a new e-mail account on their server and provide the SMTP details or sign-up for a third-party SMTP server.
What is the solution for this? Is there no way around SMTP?
Most emai/MTA server "autoconfigure" themselves. They guess list of local email domains (doimans with locally hosted mailboxes).
In sendmail case you can turn it off adding the following line in sendmail.mc:
define(`confDONT_PROBE_INTERFACES', `True')
Documentation : cf/README - confDONT_PROBE_INTERFACES
I have had the same issue many many times (in my case using PHP on a LAMP stack).
Try/check the following.
If you are using cPanel or similar, set the MX records to the external mailserver (Google apps etc).
Set up an SPF record to allow your hosting website to send email (this way no need to configure SMTP).
This may not be applicable but if you are using something like phpmailer. Set the property $mail->isMail(); so it tries to use your SPF allowed local mail() function to send the email. Sorry for going off into very specific advice, but might help in your particular situation.
Worth checking there are not similarly named local mailboxes on your hosting box.
Hope this helps!

How to get the Reply Emails ? Need a Mail Server?

As i'm knowing just about PHP and don't know at all about Mail Servers, what i want to know here is:
How can i get the "Replied" emails (from the receivers) for the mails i've send (by using PHP, with a address like xxxxxxx#gmail.com)
Does it need to setup my own Mail Server?
Unless using own Mail Server, is there any other easy way?
Honestly i'm not well understanding over IMAP or Email Protocols. Doing setup my own IMAP Server is far worse. Can it be done simply with a Web Hosting which supporting IMAP protocol? Or do i need to setup manually out from the start?
To be brief, i need a simple guide.
You only need a mail server if you don't already have a place where those reply-tos end up. Which adress are you sending them as? Where would you fetch the emails for those adress? You can ask PHP to log into any mail server that you'd fetch your emails from manually as well, so there shouldn't be a problem. But maybe I'm not getting you right.
Simply put the reply address to an email you own. For the example you gave to work, you would need to have the xxxx#gmail.com account.
Most people use something along the lines of mailer#youdomain.com, ans then create an account for that on their ma8lserver.
If you want to use your own domain, you don't need to run your own mailserver. Gmail, hotmail, and others have services that let you use their mailservers for your fomain, for free.

A couple problems re: CodeIgniter emailer

I have some problems with the email system for CodeIgniter:
First, the emails I send out (registration, confirmations) are getting caught in standard spam filters in gmail and other mail clients. How do I get around this? How do companies like Facebook get their emails through consistently?
Second, the mailer is working locally but once we deploy it it no longer runs (doesn't send emails) but all the other forms run just fine. Anyone ever run into a problem like this?
Thanks for all the help!
I can't really answer your first question - it's not specific to CodeIgniter. You just need to make sure your email doesn't look like spam. In short - there's no way of guaranteeing your e-mail will not end up in a spam filter.
As for the second question, I expect your production server needs to be configured properly for email. You probably need to configure CodeIgniter to send email properly. I would suggest setting up an SMTP server (or using an existing one) rather than using the standard PHP mail which I think CodeIgniter uses by default.
Regarding spam, most organisations are very secretive about how they prevent spam (not wanting to publish information which helps the spammers) and in some cases they don't actually know - an obvious examlpe of this is bayesian filtering - but, for example, hotmail use a completely unaccountable army of volunteers to manually classify emails.
Do and get a copy of spamassassin and try to reverse engineer how the standard rules work. Obvious things to check are:
1) AVOIDING LOTS OF CAPITALS
2) don't mention the 'V' word
3) make sure you've got a current and restrictive SPF 1.0 policy published
4) make sure your sending from an address which has A and PTR DNS records
5) Do provide a reply-to and from email address which use your domain in the address
the mailer is working locally but once we deploy it it no longer runs
doesn't send emails
Which? These are 2 totally seperate things. If the code is falling over (if so why have you not provided the error details) then its likely a PHP version issue or a problem with the connection to the MTA (or the PHP mail config).
The latter is a problem with the MTA itself.
99.9% of problems reported as PHP mail failures have nothing to do with PHP and are problems with the MTA.
Enabled detailled error reporting for your MTA and see where it is failing.
C.
You may have to configure the email on your server differently than your local development environment. I've had to in the past.
There are two basic ways that PHP can send mail:
Via a UNIX program called "sendmail" (only on non-Windows servers and only if it is installed - check with your hosting provider)
Via a SMTP server.
If you've configured CodeIgniter to use SENDMAIL, check to ensure that the Sendmail path is correct. Your hosting provider usually provides this somewhere in their online documentation.
If you're using SMTP, you need to make sure that your server can contact the SMTP server. You can do this by logging into the server via SSH and typing "telnet your.smtpserver.com 25". If you get an error message about not being able to connect, you know you have a problem with your hosting provider connecting to your mail server.
I've been able to diagnose this problem by enabling logging on my production server (http://bit.ly/4pprd6) and adding log_message('error', $this->email->print_debugger()) right after I attempt to send a message.

Is there a SMTP mail transfer library in PHP

I want to write an email transfer service and need a MTU replacement of sendmail/postfix.
I'm not looking how to deliver to a transmitting SMTP server (like a postfix listing on a SMTP port). I also don't need the receiving part of the server, bounces etc. would go to a different existing postfix.
All of it in pure PHP. SMTP is a pretty easy protocol but this would require access to the MX DNS record and other lot of details that need to be taken care of.
Why do i need this? Because most shared internet providers have insane low limits for sending out emails like 500 per day. Thats almost nothing if you want to setup even the lowest traffic email list.
EDIT: Please Note: The code needs to connect to the receivers SMTP server and deliver the message with an adapted header set (removed BCC list, added Path route). If you see a SMTP class less then 5000 lines or requires you to configure a SMTP hostip and port then this is not the stuff i'm looking for.
It needs to do all the stuff sendmail is doing just as a PHP library.
I use Pear's Mail class.
EDIT
After re-reading this, I see there's more to it than just a library. You are asking to send direct to the remote MX.
Why reinvent the wheel? Set up an instance of postfix on the server, which only listens to connections from the web server... and let an MTA do what it does best. Hand off the messages from php to a real mail server and move on.
In the case of ISP's that block outbound port 25 and force the use of a smarthost, this also allows you to restrict the rate of messages sent to the smarthost.
Lastly, sending straight to the end MX from your php script is a bad idea, because if you send to me, I'll never get it. I and many other sites use "greylisting" to reduce spam, which denies all initial requests with a 450 temporary error. Real MTA's will try again, but unless you implemented a delay queue and try again, your message will never go through.
We use http://sourceforge.net/projects/phpmailer/ to do SMTP email from PHP
SwiftMailer is the only library you'll need.
Try Zend Framework component Zend_Mail (you can use the component independently of the entire framework).
Here is something I wrote. It's quite minimal and I don't know how well it performs, but I wrote it with the intention of replacing sendmail, meaning that it will take a message, lookup all the MX records for the recipient domains, contact those mail servers and deliver a message for the corresponding recipients. It worked well enough for me at the time.
https://github.com/denvertimothy/ThriveSMTP
It's been a long time since I've used it, but I threw it up on Github just now.
I used http://www.mailerq.com/ which works cool. Its a queue based mail transfer agent. It requires rabbitmq.
It provides multiple worker as well.easy to store in database.
It provided management console as well.

is there something wrong with using php's native mail function?

i tried googling but sadly i get only documentations (or am i using bad keywords)
anyway
i can see that alot of programmers (even those im working with right now) does not seem to approve to using the php native mail function and resorts to using some other framework like sendmail? swift mailer etc...
i'd like to know why? are there really disadvantages to using the native mail function?
if so how does the mailing frameworkds solve that or how are they better??
There's nothing wrong with it for sending simple plain text emails.
However, once you get into multipart mime emails (say, you want an HTML version or to add an attachment) then you have to build the email yourself, and it can be quite tricky to get all the headers and encoding correct. In this case you're better off using a library.
The PHP manual for function mail mentions that there are some restrictions with the mail function and one of these are that the function opens and closes an SMTP socket for each email. The mail function works good when you just want to send a mail or two.
As far as I'm concerned, all of these problems pale in comparison to the major security problem:
Mail header injection: ( http://en.wikipedia.org/wiki/E-mail_injection , and php specific info: http://www.damonkohler.com/2008/12/email-injection.html )
Whereby a spammer bot spiders your site and, finding a vulnerability in your script that is easy to still have when using the very insecure mail() function, IS ABLE TO SEND EMAIL FROM YOUR SERVER TO AN ARBITRARY LIST OF CONTACTS, essentially turning your script & server into a cog in their spam email machine.
I recommend never using mail() with user input, and in general, just making use of PEAR::mail instead. http://pear.php.net/package/Mail/
Using PHP's mail() function requires a properly configured sendmail or equivalent on the host the program is running. However, the Windows implementation is a bit different. If you don't have your MTA configured properly, you won't be able to successfully send emails from your PHP scripts. Like another commenter said on this thread, PHP manual explicitly states that each call to the mail() function opens and closes a socket. This can cause unnecessary delay in script execution.
Additionally, your development and testing environment may not have a public static IP address. Your IP address might be blacklisted by DNSBL, Gmail, Yahoo! and other popular email service providers.
Your best bet in this situation is to use a properly configured external SMTP server. Chances are your employer has already provided an email account with SMTP access. If you don't have one you can use a Gmail account. Gmail provides SMTP access to all email accounts.
You can write scripts to open a socket connection to the external SMTP server. When there are tried and tested open source libraries for this purpose, why write your own?
Incidentally, I wrote a blog post on the very same subject yesterday: Using SMTP With Zend Framework - Solve Email Delivery Problem
