imapsync: Can not open imap connection: Connection refused

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 !

 

is your imap server actually runing on --port2 164 ?
or you redirected from your router external 164 to internal 143 ?
are your sure that the server isn't firewalled on the imap port ?

 

I'm really running imapsync on ports 143 and 144. I just changed the numbers in the thread to obfuscate.

1) I don't know how to verify on which port imap is running. I assumed it was port 143
2) I'm certain I'm not redirecting via the router
3) I don't know how to check if there's a a firewall blockage

If you could provide me with details, I will take a look and report back.

Thanks !

 

the easyest way to check if you establish the connection is with telnet
like if you're runing imapsync on the server where you will copy the mailbox

Code:

telnet mail-server.to-transfer.from 143

if this gives you connection refused or time out then you should check on that server from a terminal if imap is actually running ,

Code:

netstat -tnlp | grep 143

or

Code:

telnet localhost 143

if this works then check your firewall

Code:

iptables -nL

and 3rd check you router if your port's are configured as it should
external ip port -> internal server's ip imap port

 

Thanks for the instructions ! I'm at work now, but will give it a try and provide an update later tonight.

 

It's Face-Palm time !

I discovered the error of my ways.

imap is running on the same port on both servers. I apparently mis-typed the command when I made my installation notes the last time I did this.

Thanks for taking the time to help me.
