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

~$ telnet 146.83.9.56 993
Trying 146.83.9.56...
^C

~$ telnet 146.83.9.56 143

Given connections to the Dovecot host are apparently firewalled, either
holes have been punched for 24.58.62.118, or you're going through a VPN
tunnel.  I'd guess your problems are network or firewall related, not
Dovecot related.
