Php – Google Apps + PHP mail() problem

emailg-suitePHPsendmail

When I send emails using PHP's mail() function from my web app I can deliver e-mails successfully to any e-mail address except to my own Google Apps e-mail account, which happens to be on the same domain the web app is on.

I've read http://www.google.com/support/a/bin/answer.py?hl=en&answer=55299 which seems to be my problem, but I don't understand what it's telling me to do. I've also looked at http://forums.cpanel.net/f43/google-apps-mail-problem-139337.html but I'm not sure if that's specific to cpanel or not.

I'm on a VPS with Ubuntu 8.04 Hardy Herron.

Any help would be appreciated, thanks!

Most MTAs (mail servers) will not lookup MX records if the local server has email setup for the domain, they will instead deliver locally. Turn off email locally for this domain (or I believe there might be a setting in cpanel to force DNS lookups) and your emails should start working.

Easiest way to do this is to avoid using exim and to use sSMTP which is a lightweight MTA.

All you need to do is install it:

sudo apt-get install ssmtp mailutils

and configure it (edit /etc/ssmtp/ssmtp.conf) to use your Google Mail servers see:

root=noreply@yourdomain.com
mailhub=smtp.gmail.com:587
UseSTARTTLS=yes
UseTLS=yes
AuthUser=youremail@yourdomain.com
AuthPass=password
FromLineOverride=YES

I've been using this set-up for a while now and it just works - It's also nice to not need to be running exim when it's not necessary and let Google's mail servers handle everything for you.

Google Apps mail “Too many simultaneous connections” error

I've ran through this problem in the past (as I was running some tests with google and google apps from different clients). I'm unsure how Google treats clients or vice-versa (as far as connections per session), but this link explains how to unlock your account(s):

Pretty much, going to the link (depending if the account is a google apps domain or a regular google account):

Regular Google account:
http://www.google.com/accounts/DisplayUnlockCaptcha

Google Apps Domain account:
https://www.google.com/a/[your domain].com/UnlockCaptcha

As far as fixing this issue. This might be something Google is working on (some Google groups posts about people having these same issues here).
