Recurring problem: outgoing server connection time out.

Posted

Hello all,

When I try to send messages, most of the time I get the following error "The message could not be sent because the connection to Outgoing server (SMTP) timed out."

Small messages sometimes slip through, messages with attachment will just not send. Yesterday everything ran fine. If I use my web client, everything runs smoothly. My other email addresses (that use other outgoing servers) work without problem.

I have had this before, always with the same e-mail account, and usually after a day or two things went back to normal. Still I'd like to fix this once and for all. I went through the suggested steps on the mozilla support article with no avail.

According to my webhost company, my server settings are correct (port 587, STARTTLS). Disabling firewall/virus (kaspersky) had no effect, neither did changing the password.

What can I do?

Just to be clear it probably is not. It is almost certainly a problem with kaspersky, which has appeared in so many threads in the past couple of weeks. The current release look like it might not be a good one.

Note that the only way to be sure you are shot of anti virus programs is to run your operating system in safe mode with networking.

Restart the operating system in safe mode with Networking. This loads only the very basics needed to start your computer while enabling an Internet connection. Click on your operating system for instructions on how to start in safe mode: Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, OSX

Hi Matt,

Thanks a lot for your response. The problem seems to have solved itself for now, perhaps Kaspersky fixed the bug. Fingers crossed!

I use BitDefender not Kaspersky and have this same problem. I booted into Safe Mode and opened Thunderbird and saw the same error message: "Connection to server mail mail.tds.net timed out" Where do I go from here?
