Hello Avast,
I use Thunderbird 17 with a gmail imap account.
receiving: imap.gmail.com with port 143 (SSL)
For sending (SMTP) I use:
smtp.gmail.com port 587 (STARTTLS)
When I want to send email I get an error that the certificate for smtp.gmail.com:587 is not good.
Do you know any solution for this.
Kind regards,
is this related to avast?
does it work if you turn off avast mail shield?
if not a avast problem, have you tried Gmail support forum?
Before I had a problem with receiving email and a certificate which was not allright. On this forum I found the solution not too use port 933 but 143. So I thought maybe this forum can help me aswell with this problem.
Avast had some problems interacting with Thunderbird. The solution will be found here:
