imapsync migration
 
Using the imapsync utility according to your how-to.
yum installed with dependencies successfully.

All parameters on command line OK.
Getting the following error after the "will try" and "From & To" lines:

"Can not open imap connection on [host1 ip] with user [username@host1] : IO::Socket::INET: connect: Connection timed out"

NOTE: host1 substituted for the actual ip addr. username@host1 substituted for the actual email user.

The server on host1 has been operating correctly for almost 4 years. Just doing a migration to a different host.

Server is Fedora 8 X64 with Apache, Postfix/Dovecot/Amavis/Clamav/SpamAssassin running on an AMD Athlon 64X2 2.4GHz 4GB.

Any help with this error appreciated.

What's the output of
Code:

netstat -tap
on the IMAP server?

Looks ok. Is there maybe a firewall that blocks access to IMAP?

seahawkja 2nd August 2010 21:46

Can do using LAN IP addr
 
Nothing in the firewall blocking imap - I think it is in the server config.

As I was using SSH to access the server previously, I decided to go in to the client and try imapsync directly on the server - same timeout result!

Tried the quick imap telnet check to server.net 143 and that was a no go.

Decided to use server's IP since I was at the site and ...voila - she speaks.


So re-ran the imapsync from another station using SSH and the server's IP and off it went.

Anyway, since the email migration is the priority now, I am proceeding with that. I still need to check on the server's config to see what's up with the imap 143 blocking for future reference if I have to do this on another server.

Thanks for those who took the time to check in on this, and also Falko for your input.

Looks as if the hostname is resolving to a wrong IP. Did you check that?
