SMTP/POP3/IMAP Mail server does not work
Link test:
https://www.checktls.com/TestReceiver
The server was running and stopped working out of nowhere, so I re-installed VESTACP twice and the mail server no longer works.
I have searched the topics here in the forum and nothing solved, will be a failure in the vestacp?
It is said that the doors are closed but I have done everything.
Code: Select all
iptables -A INPUT -p tcp --sport 587 -j ACCEPT
iptables -A INPUT -p tcp --sport 25 -j ACCEPT
/sbin/service iptables save

But, have your provider that ports opened ?
From SSH try conect with telnet or netcat to port 25 from localhost
Also check if exim is runing "service exim status"
May be your provider restrict access to port 25 ( some providers do )

[root@srv ~]# service exim status
exim (pid 1232) is running...
My vps provider has reported that the ports are cleared.
I do not know what else to do.

Hello,
Chain INPUT (policy DROP)
target prot opt source destination
fail2ban-SSH tcp -- anywhere anywhere tcp dpt:ssh
fail2ban-MAIL tcp -- anywhere anywhere multiport dports smtp,urd,submission,ms-v

fail2ban-VESTA tcp -- anywhere anywhere tcp dpt:us-srv
fail2ban-FTP tcp -- anywhere anywhere tcp dpt:ftp
One of the services running on the machine is invoking fail2ban to create firewall rules. You will need to disable it within the service. Its not uncommon for this to be a part of web hosting packages, so that would be the best place to start.

Send me private message with your hostname / IP or what uri you use for test
In any case, you have open ports in your vesta firewall ?

RESOLVED.

Your service appears to have been ACL'd with no indication on our end.
I have removed the ACL from the service.
Now it's passing SMTP traffic :)
Thanks.
