I've tried using Postfix only as a SMTP server for sending "verification" mails locally, to any provided destination. The current problem is, it sends all mails without any issues but receivers don't get them.
I'm using XenForo software with "127.0.0.1:25" SMTP data for sending mails, without user - / pass login because Postfix is locally bound and should only send mails - not receiving any from outside.
Also I'm using my custom domain to provide "from:" data for mail. (e.g. "no-reply#*******.com")
I already tried using SMTP servers of different hosts such as "MailJet" but I had the same issue there. The staff of used hosts said, there'd be something wrong with my server and nothing else, so that's why I had decided to host an own SMTP server locally on the same server as like as my webserver's running.

Thanks in advance.

And you have SPF, DKIM, etc. all sorted? I suggest you (authenticate with and) use the same SMTP server you use for all other email from that domain, create a separate inbox if you need so it's using different credentials to you. It's usually a lot less hassle.

Setup:
Ubuntu 16.x, Postfix, PHPMailer
SocketLabs (mail relay service) - to send out server emails
Union Solution Exchange Server - to send and receive formal email from outlook
Im trying to send out emails from my ubuntu linux server that contain simple form data (name, message, phone etc).
I have been trying in vain to send emails from my PHP to emails, they send, but they get blocked as spam/junk.
I've recently switched mail services (from zoho to a solution union exchange server) and I cannot get past barracuda (even modifying whitelists / spam settings etc) with my own mail, but I can see them as junk in my hotmail. (cannot not send from mailserver#potlickers.com to support#potlickers.com). They get immediately canned and not delivered.
Solutions Union said I was spoofing the emails and I cannot whitelist my own domain I'm using and sending from? Ok. They suggested buying another domain. I now own potlickers.net.
They also mentioned I should take that domain and use it to send my emails via open relay (again socketlabs).
So, if my webserver is setup on a fqdm such as potlickers.com, and i send the mail from that server, how do i setup the correct architecture to send mails from potlickers.net to the open relayserver so my emails are free and clear and not spoofed?
Can i configure postfix to send mail from potlickers.net even though its hosting on blah.potlickers.com?
I understand to also add dkim and PTR.
Help stackoverflow1 - your my only hope. TIA much much mucho thanks.
So I think I got it.
Reconfigured postfix as a satellite. Pointed to smtp of relay mail server. Removed all SMTP settings in PHPmailer that point to server, and credentials.
Fire away - works like a charm.
Satellite server has the new domain potlickers.net versus the webserver domain potlickers.com
Seems to work ok for now. Will update moving forward.
This is quite strange as email sending using my Gmail SMTP server works in my localhost, but when I deployed it on a VPS, it wouldn't work at all.
I can't find any issue as to why this is happening, the configuration looks normal (SSL port 465, Gmail SMTP server). I'm using Laravel 4.0.9 so I thought of upgrading to 4.1/4.2 to use the Mailgun feature (not sure if 4.0 can use Mailgun?)
Anyway, for a quick fix, I just switched to mail method for email sending. Since this works well for me, my question is that whether there is any tradeoff of using mail instead of SMTP on Laravel? The delivery seems okay as it got to my inbox, but what about the long term?
Any thoughts would be very much appreciated :)
When using the built-in mail function you don't benefit from additional features such as DKIM and the SFP configuration for your domain may not allow hosts other than your SMTP mail server to send mail for your domain, all of this makes the mail you send that way look like spam to other servers.
While you may not have issues with some providers, try to send mail to some more restrictive providers such as Outlook (ex-Hotmail); I'm pretty sure all the mail you send there will be automatically marked as spam because of the issues described above.
PHP mail may be faster since you don't have to connect to your smtp server, but it's not better. In the long run, SMTP email is the only way to guarantee that your email will arrive in the inbox of your receivers
So, I developed this web application which needs me to send emails to everyone (details in a mysql database), providing a unique set of user credentials. I have a virtual server on the University network where I am hosting my PHP based application, so it obviously doesn't have its own mail server/SMTP settings.
So, if I were to send out mails from a university network, I guess I should request the network admin for the SMTP settings for the university mail network and then use PEAR for it right?
I need to confirm this because it's kind of a big deal to make a request like that, and I myself have never used PHP to send mails 'from' an external email id not linked to the server.
Are there any alternatives to this?
Yes you can use PEAR::mail to send mails via SMTP server. However, if SMTP is configured on localhost you can simply use mail() function to send mail. You can also connect to SMTP server via socket but then you need to handle whole protocol communication.
I am trying to send an e-mail from localhost but am getting the error:
Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set().
Does this mean i need to set up a local mail server?? and if so how and which one is easiest.
Thanks in advance

This is what I use, but it's for testing purposes only:
http://www.toolheap.com/test-mail-server-tool/
There's almost no configuration, and I got it to work right out of the box (on Win7) after failure with several other mail servers. It does not send the actual mail, but stores it as an .eml file. This is great for testing mailing lists for instance, where you don't really want to send the 2000 emails, but want to get a realistic result from your application.
It might look like garbage, but it's been working great for me.
Yes, it does, and if you want to send mail to an outside email address (and not a user local to the system, it is annoyingly difficult).
Most hosting companies (e.g. GoDaddy) have this setup for you, so PHP's mail() function works without you needing to do anything.
If you're configuring it on your own system, you might want to consider (a) configuring sendmail to use an alternate SMTP gateway (I frequently use Gmail) or (b) a complete alternative to sendmail (Zend Mail looks promising.)
If you are using Linux, there is usually no need to set up a a mail server,
If you are using Windows, yes, you do need to set up a mail server
If you are interested in just sending mail, you can by SMTP protocol use any SMTP server. Here is a tutorial to setting up PHP to use a remote SMTP server.
Yes, you need a mail server to be able to send mail, but even if you do, you are not going to be able to send to addresses outside of you local network as mail from your computer will be blocked by all recipients for spam reasons.
You could use the pear mail function to connect to an external smtp providor like gmail to send the mails for you. More info here and here.
smtp4dev is in my opinion the best tool for capturing local SMTP traffic on Windows.
It listens SMTP on localhost port 25 and pops up a notification every time a new mail is posted (it doesn't actually forward the mail to its recipient). You can then open the message in your favorite mail agent or save it to a file.
I'm building a site on my home computer using MAMP. The code I'm using employs the PHP mail() function to send emails, but whenever I test it, the mails aren't getting sent.
My computer is connected to the net, but I'm wondering if there's something about local hosting that prevents mails from getting sent. I'm not getting any kind of error message.
Any ideas?
PHP can send mail in one of two ways.
The first, and the default on non-Windows systems, is to use the local mail transfer agent installed on the system. This would be "sendmail" or an application compatible with it, the most popular probably being postfix.
The other is to connect via SMTP to some mail server.
You will either need to install a mail transfer agent on your local system (and set it up correctly), or edit PHP's configuration to specify an SMTP server address and port.
Yes, there are things that could block locally hosted mail. For one, your ISP could block SMTP to servers other than the ISP. ask your ISP support if they block SMTP... Or try telexing so someone's MX port 25 and do you get a response?
If your ISP blocks smtp you can still send the mail, but first you must relay that email through a hosted email server like your ISP mail server. This process is called 'smart hosting' and you can search for more info.
Even if you are not blocked on port 25, many sites will refuse or lose smtp traffic that originates from a dynamic or residential IP address, so again the smart host suggestion.
Also I suggest not using the built in mail() function in PHP... Use something that replaces and improves it like http://pear.php.net/package/Mail or http://sourceforge.net/projects/phpmailer/. Again, use the SMTP method as it is way more reliable than direct sending or calling Sendmail.
It is important to confirm this problem, doing SMTP manually over telnet. That way you isolate the problem from PHP. I did ISP support for years and saw this question lots. Most people setup php and mail correctly but get stuck on a background network issue with SMTP.
If you have Wireshark installed, it can record network traffic and you might see the actual SMTP traffic, for example the remote server may be refusing your connection. Wireshark is helpful but not required to solve this though. Good luck.
You need to setup SMTP server in order to be able use mail function, or you can use PHPMailer class, with it you can avoid using mail function and setup problems, PHPMailler need socket extension to be loaded in order to function correctly.
