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.

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?

I have the same problem of outgoing emails OK but if 6 Mb attachment added I get a swift green 100% bar followed after about 1.5 minutes by smtp time out. Thunderbird 60.6.1. ISP says 25 Mb is accepted. Thunderbird settings not changed.

A test with a 1 Mb photo attached was sent ok, but a 3 Mb photo failed. The time out problem seems to be related to file size but why so small ?

There is one generic answer for all timeout issues.

If you have an anti virus program scanning outgoing mails, disable it. Scanning outgoing mail is a useless feature anyway as the product assures you that you have no malware and malware does not spontaneously appear. IF it were to find malware in your outgoing mail it would be proof positive that it was a rubbish anti virus product.

If you have a very slow internet connection try it on a faster connection.

Thank you Matt for your help.

I was a bit reluctant to turn off scanning outgoing email although I understand your reasoning that it should not really be necessary if all external sources are checked.

Anyway it worked and my 6.5 Mb zip file could be sent. The green bar slowly but steadily progressed to 100% (normal) and I think the email completed after about 4 minutes.


My internet broadband upload is typically around 0.4 Mbps and download 1.5 to 2.5

Perhaps the time out could do with some user controllable settings. Maybe this explains the somewhat random occurrences of other users experiencing this problem with varied AV software and different versions of Thunderbird. If like me they rarely send a large attachment, the date of discovering the problem may be a false indication of how long the problem has existed on their system.

How do I mark it solved ?

Kind regards

Sorry for the confusion. I found this thread after I had entered a search question. When I made my 12:26 post 5/20/2019 I wrongly assumed my comment was about my question.


This explains why at 15:28 I could find no way to mark my question as solved as solved.

Anyway thanks again

You could view it that way, but if you installed a new lock on your front door that took 4 minutes to unlock and your porch sensor light turned off while you waited for it. Would you adjust the light timer or get rid of your mistake where the lock was concerned and get one that actually worked in a timely fashion.

Many people complain that windows gets slower and slower and so they buy a new computer. They could get a typical 10 or 15% increase in performance just by uninstalling their anti virus but they do not. The so called "security" companies sell their products based on fear and ignorance. Do not get me wrong. Malware is a very real threat. But they use fear marketing not quality of product marketing. That combined with the issue that all the anti virus ranking sites are paid for by the anti virus vendors (they pay to be included in the testing) and really finding the best product, or even the least destructive or fastest is not anything like as simple as it should be.
