Have you performed extensive packet tracing to eliminate the network
paths as the source of the problem?  From here...

~$ telnet 993

~$ telnet 143

~$ telnet 25

~$ telnet 587

Given connections to the Dovecot host are apparently firewalled, either
holes have been punched for, or you're going through a VPN
tunnel.  I'd guess your problems are network or firewall related, not
Dovecot related.
