Flummoxed by external SMTP problem - El Forum - 06-29-2012
[eluser]Unknown[/eluser]
I've gone through and through my external smtp server and haven't found anything wrong with it, so the problem must be with EE.
I'm posting in the codeigniter forum because the first four error messages I get refer to the codeigniter Email.php library.
I'm on EE 2.5.2. I'm hosting both the WAMP stack serving EE and the mail server on separate EC2 instances at AWS.
The behavior: Using "Communicate", and configuring for External SMTP, I get two minutes of spinning wheels, a timeout, and a page of errors. From the mail server side, it just looks like it receives an incoming connection, gets nothing further, then closes the connection after about two minutes.
Here is the entirety of one of these events on the mailserver's log file (It's Smartermail, ironically)

Here is the series of errors I'm getting from EE after the timeout. The big kahuna appears to be

Unable to send email using PHP SMTP. Your server might not be configured to send mail using this method.
Anyone have any clue why EE or CodeIgniter wouldn't send "AUTH LOGIN", or be able to communicate effectively (or at all) with the mail server? I've checked all the security settings, AWS security groups, firewalls on the individual machines, I can telnet to the mail server on both SMTP ports just fine, and I use it every day to retrieve and send email via POP3 and SMTP. PHP Mail works on the local EE machine, but I wanted to centralize all the email service for both of my web servers.
Of course, any help will be met with undying gratitude and perhaps I can order a pizza delivery to your house. Thanks!
