SMTP From Joomla?
Joomla SMTP PHP Mailer objects use port 25 by default when SMTP is set as the mailing option within the Joomla Global Configuration. I hacked the core Joomla V1.0.15 PHP mailer class implementation and hardwired (for testing) the SMTP port from 25 to 26 as noted in the above HOWTO for sending plain text mail. So far this solution is not working from a Joomla PHP mailing script point of view.

All programmatic send requests to the Joomla SMTP mailing script return with Connection refused errors from the remote SMTP server. I can send perfectly fine connecting with the exact same user info and port number from a local mail client.

I have tried various other configs like using SSL over port 465 rather than clear text over port 26. The SSL sends seem to create other problems however.

S U G G E S T I O N :

A nice HOWTO on getting PHP mailing scripts working problem free on Host Gator mail servers would be very useful!, (Please start with Joomla 1.0.x - 1.5.x) Thanks in advance!
