Up until the end of August, I was able to send emails with no issues using Thunderbird version 17.0.8 using Windows 8.
In the past few days (in September only - that seems related somehow!) I've been getting this timeout message when I try to send any emails from Thunderbird:
My outgoing server settings have always been the following (and have worked up until the month of September):
No authentication or security.
Anyone know why I am having this problem NOW? And what I can try to fix it?
