Unable to send mail via SMTP

[random539]

Hi all,

I recently migrated my forum from a hosting provider to a server I set up at my house.  Here's my version info:

SMF 2.0.19 (yes, I'm planning on upgrading to 2.1 soon)
PHP 7.4.33
MySQL 10.9.4

Everything's running great except I cannot get the forum to send emails via SMTP (before I think I was sending via the builtin php function).  I've tried prefixing the server name with tls:// and ssl:// as well as trying ports 587 and 465.  I can connect to the smtp server via telnet on both of those ports.  The server in question does not listen on port 25 - might that be a problem?

I have access to the SMTP server in question and thus am able to watch the logs, but I don't see my forum even trying to connect.  Another concern is I do not see anything mail-related in my SMF log, which makes troubleshooting difficult.

Anyone have ideas on what to do next?  It would be great if I could see output from Subs-Post.php but I have no knowledge of php so I'm not sure how to go about that.

Thanks!

I figured it out; part of the problem was that I was testing by mentioning myself (which doesn't trigger an email notification) and the other problem was I was grep'ing my mail log by username and not IP.  After figuring that out I was able to discover that I had to use port 465, and the host has to be prefixed with ssl:// or tls:// (for my SMTP server anyway).

1. You're not cluttering up the board because someone else having the same problem could find the answer in your post.

2. As for stupidity, I wouldn't call it that since we all do it.
