I had to do a migration because the OS was done with security support. I migrated and I've had a lot of trouble sending email.
I've manually setup PHP Pear Mail:
- Auth_SASL-1.2.0
- Net_SMTP-1.12.1
- Net_Socket-1.2.1
- PEAR-1.10.15
...in order to send clean authenticated emails like on the previous server. So I kept hitting an old error and was told I was running an old version, fine - I got the latest versions of everything until I hit a problem that wasn't a missing file:
fsockopen(): Unable to connect to mail.example.com:465 (Connection refused)
Further investigation in to the file /var/log/exim_mainlog revealed:
2024-07-02 05:13:12 TLS error on connection from [---.---.---.---]:43464 (SSL_accept): timed out
For further PHP debugging information please see the bottom this this post.
So most the solutions for the problems I've encountered are things I end up fixing through WHM. There are firewalls and other security software/plugins/etc. I've read on a Plesk thread that Imunify360 can disable sending emails except for specified Linux users though that option was disabled. I looked through the software listed under plugins. I looked through Exim related pages.
So I'm at a loss as to what is blocking the email from being sent. Worse yet, every test completely locks up the server for 10 minutes short of me forcing a server reboot.
Looking at related questions I ran this command and apparently there are processes sitting on port 465:
[root@server:/root]$ netstat -lnp
tcp 0 0 0.0.0.0:465 0.0.0.0:* LISTEN 317/exim
tcp 0 0 0.0.0.0:465 0.0.0.0:* LISTEN 317/exim
tcp6 0 0 :::465 :::* LISTEN 317/exim
I would be very grateful for any insight in to what could be stopping my mail from working please.
