If i configure mozilla to connect to 127.0.0.1 and append the imap server name to my username, mozilla cannot resolve the host address of 127.0.0.1
Do you use port 143 in your IMAP account ? Don't you use SSL ?
Is this a port problem? i've scanned my open ports and port 25 is closed. Should it be open?
When Mail scanner (ashMaiSv.exe) is started, ports 110, 25 and 143 should be open, but only for local access (through 127.0.0.1).
