Cannot receive emails

[deogo032]

Hi, i need some guidance to solve this problem
I have three email accounts, which do not receive incoming emails, though outgoing emails can be sent fine
i have setup in thunderbird, but entering through webmail i don't see any emails either
yesterday i was experimenting a bit - tried to disable antispam/antivirus/fail2ban but it didn't help, and at some point even outgoing emails stopped working
i have ports 143/993 enabled in firewall (tried both)
what logs should i check first?

debian 10/myVesta 0.9.8-26-47

Check if MX record of domain is pointing to your server - https://mxtoolbox.com/

Also check if you can connect to 25, 468 and 587 ports from outside.

really, ports 25, 468 were disabled in firewall, now mails received normally
now i remember how disabled those ports shortly after installation, because read somewhere they should not be used.. feel stupid

thank you for quick help, much appreciate it!
btw, your cp was the only one i could easily install, setup and run without any problems, given i don't have much knowledge in web, really great work!

Why port 468?

On vesta I see the following ports are needed for smtp 25,465,587,2525

My emails were working and suddenly email are not coming in.

I think it's because port 468: It’s uncommon to see port 468 used for SMTP services.

The standard ports for SMTP are:

25: Used for plain text communication.
465: Used for SMTPS (SMTP Secure), which is SMTP over SSL.
587: Used for SMTP with STARTTLS, a method to take an existing insecure connection and upgrade it to a secure connection using SSL/TLS.
2525: Often used as an alternative to port 25, especially for outbound mail when ISPs block port 25.
