Avast is causing Thunderbird to not work. Has anyone else had this issue or similar error message to the ones I get? I posted them below and and in two other replys to this post. If anyone uses thunderbird 3 and Avast 5, can you please post you settings? I would really appreciate it.

My e-mail worked fine until I installed Avast. I can no longer send e-mails and Avast does not even scan in- or out- going mail.
TB says:

"Sending of message failed.
The message could not be sent because the connection to SMTP server timed out. Try again or contact your network administrator."

When I disable all SSL:
"Sending of message failed.
An error occurred sending mail: Unable to authenticate to SMTP server It does not support authentication (SMTP-AUTH) but you have chosen to use authentication. Uncheck 'Use name and password' for that server or contact your service provider."

In Avast:
Troubleshoot settings are all clear fields.

For IMAP (gmail)
Port 993

For POP (gmail)
Port 995

For POP (live)
Port 995

gmail (IMAP)- Port 587
Gmail (POP)- port 587
live - port 465

Any Ideas???? I'm starting to go crazy! I attached some screen shots...

BTW, I looked through some of the other forum posts on this topic but nothing has worked so far. I need my e-mail...

Here are some of the errors I currently get (attached)
For now I have SSL on in TB so that I can receive e-mail.

More screen shots of TB settings.

I tried to run TB without IMAP/POP SSL choice but I stopped receiving e-mail altogether.

I fixed it!!! ;D

In Avast my SMTP needed to be set to TLS for both Live mail and for Gmail. Also under Avast troubleshooting I needed to add 587,25 to SMTP ports.
