Hi all - I've just set up a new Debian "Squeeze" server and discovered imapsync was no longer part of the distribution. Fortunately, I kept a copy of the old package and installed it, including the related support packages. When I issue the imapsync command: imapsync \ --host1 <SourceServer> --user1 <EmailUser> --password1 <Password> --port1 163 --authmech1 LOGIN \ --host2 <DestServer> --user2 <EmailUser> --password2 <Password> --port2 164 I receive the error: Can not open imap connection on <DestServer> with user <EmailUser> : IO::Socket::INET: connect: Connection refused I used the following instructions from "The Perfect Server - Debian Squeeze (Debian 6.0) With BIND & Dovecot [ISPConfig 3]" I double checked my router ports and they seem fine. ifconfig on the <DestServer> displays the correct IP address, but I cannot Telnet to it using port 164 (hence the connection refused error). Can anyone help me resolve this ? Thanks !
