I guess I've been lucky. My Red Hat server I built in 2003 finally gave up the ghost yesterday. Fifteen years with almost zero problems running 7x24. Now I'm trying to build a basic server to host my e-mail using CentOS 7, Sendmail and Dovecot. Server is running great as are Sendmail and Dovecot but Dovecot only allows connections from the CentOS 127.0.0.1. I can telnet localhost pop3 and get a +OK Dovecot ready response. Trying to telnet from a different computer on same LAN times out. I've looked at my old Dovecot config files to see how I enabled LAN IP access but the configs have changed a lot since I last installed Dovecot. Googling hasn't helped. Anyone help with a sample config with LAN IPs permitted?
Did you verify the server is listening on 0.0.0.0 and that your firewall is not blocking?
tcp 0 0 0.0.0.0:993 0.0.0.0:* LISTEN 2325/dovecot tcp 0 0 0.0.0.0:995 0.0.0.0:* LISTEN 2325/dovecot tcp 0 0 0.0.0.0:110 0.0.0.0:* LISTEN 2325/dovecot tcp 0 0 0.0.0.0:143 0.0.0.0:* LISTEN 2325/dovecot

CentOS 7 uses firewalld. You'll need to enable the services you use (smtp, imap, and pop3) for the default zone. Something like:
firewall-cmd --zone=public --add-service=imap --permanent
firewall-cmd --zone=public --add-service=pop3 --permanent
firewall-cmd --zone=public --add-service=submission --permanent
firewall-cmd --zone=public --add-service=smtp --permanent

Did you remember to permit access in firewall? You can use ss -ltnp to see what address(es) are listened on.
