Hi,
I have been using Thunderbird and Avast free edition for some time. Since a couple of days ago, I can’t send e-mails using any of my accounts, but I can still receive e-mails. I get the following error message (the first line is my translation to English):
An error occurred while sending mail: The e-mail server sent an incorrect hello text:
Cannot establish TLS with SMTP server XX.XX.XX.XX, SSL_connect error 38.
I am using Thunderbird 3.1.10 and Avast 6.0.1125.
Could this be caused by Avast? Any ideas how to fix it? Thanks!
Did this problem just occur after upgrading to the newest version of Avast or can you relate this problem to any other changes you did on your machine?
Is your machine acting fine other wise?
Are your settings for Avast set at default or did you make any changes?
I do not think it started with the very last version of Avast. After the problem occurred, I checked for an update to Avast to see if that might solve the problem, and that’s when I found and installed version 6.0.1125. (I update fairly often, though, so I was not using a very old version either.)
Yes.
I’m not really sure, it’s been a while since I configured it. Anything in particular I shoud look for?
In reviewing your recent posts, I noticed that you may have had or had some malware issues this past year. Have you done Avast scans and MBAM scans to rule out malware?
So this problem has been going on for several version upgrades of Avast? At least for version 5.0 - the current version?
What is your firewall and is anything blocking your email or Avast?
No, that is not the case. The problem only started a couple of days ago, and I have been running version 6 of Avast for some time, at least a couple of months, I think.
I’m using the Windows firewall. Can’t find anything that I think would block e-mails.
Yes. When I click “send” i get the error message. Before I click OK to remove the error message, the e-mail window is open with the progress bar says “Connected to [mail server]…” When I click OK, the progress bar disappears.
SSL/TLS is disabled in Thunderbird for all accounts.
Okay, then try this:
Close Thunderbird.
In Avast, go to Mail Shield, Expert Settings, SSL-Accounts. Delete all accounts listed there.
Reboot and start Thunderbird, check your email-accounts (receive + send).
I had disabled SSL/TLS for all accounts, but not STARTTLS for outgoing SMTP server. I tried disabling this now, with no luck. (Should I delete all SSL accounts under mail shield / expert settings and rebooot?)
I really appreciate your help! Sorry if I am not being clear. I have not touched any of these settings, and everything has been working until now.
I have absolutely no idea why it suddenly stopped working. As I said, I haven’t touched the settings in Thunderbird, so I assume STARTTLS has been activated for outgoing SMTP all the time.
