…no idea why, works fine with Windows Live Mail, ie setting the account to non-ssl ports and getting IMAP rerouted by the mail shield. Required server settings are the same like Gmail.
I noticed when I first tried that in Thunderbird that Avast detected (for some reason ??? ) a POP account. Corrected this and it still doesn’t work. IMAP alone is affected, SMTP works with the mail shield.
So again, IMAP/SMTP (143/587 >>> 993ssl/587tls) works fine in Windows Live Mail while just smtp works in Thunderbird. If I don’t use the mail shield and set back the account to ssl settings in Thunderbird of course IMAP works again.
Any clue?
ps: no error message, just Thb telling that connection with myopera.com timed out.
