I upgraded to 31.3.0 and now can not receive e-mails, even though I can send them.
Have used Thunderbird for years, but have not been able to receive e-mails for two days since the upgrade. Able to send e-mails, but not receive. Tried deleting e-mails for last few days on server and on Thunderbird, but no change. Tried deleting saved password on Thunderbird, but it only asked for new password when sending e-mail, but does not ask for password for receiving. Tried re-installing Thunderbird, but no e-mails received.

I solved the problem by changing Account Settings / Server Setting changed the port to 995 (default was 110) and the security to SSL. (Not sure how the upgrade changed these settings).
