One of my systems has six email accounts set up in TB and the passwords are all stored in TB’s Password Manager. Assume that I’ve turned off AVG’s email scanning and the Comodo Personal Firewall (CPF) is correctly configured and active. If I tell TB to get all mail, it might get them all or it might respond that the third, fourth, fifth and sixth accounts can’t be contacted because of a bad password. If I turn off the automatic login and password so TB will prompt me for each password, it works fine.
The multi account fetch error isn’t 100% consistent. I’d say it fails around 90% of the time.
Is it possible that the Comodo firewall is caching the previous password a little too persistently for TBs liking, or the firewall isn’t correctly detecting the required change of credentials when TB finishes checking one account and switches to the next?
If CPF is disabled, multi account email fetch works. Turn it back on and it fails approx. 90% of the time.
