Hi,
I have been using thunderbird for a long time to send emails via SMTP through gmx.net with the default port 465. Since several days there is constantly a temporary problem 4.3.0 coming up. I can still send emails directly via the gmx.net website, and settings have not changed with them or on my computer (I checked them). So, it does not seem to be a gmx.net or thunderbird issue.
When trying to send emails, thunderbird says that it connects, and then the progress bar reads "Delivering mail...", but after a minute or so concludes:
An error occurred while sending mail. The mail server responded: 4.3.0 Temporary problem {mp029}. Please check the message and try again.
also other {mpXXX} codes came back, mp027, mp031 etc.
Thanks for any ideas how to solve this problem!
Sven

Do gmx.net provide a user forum where this problem might have been raised?

Thanks, I tried the GMX user forum first before posting this here, but I did not find anything useful there apart from one entry which suggested in a somewhat similar case that my problem may have to do with the internet provider. Or could it have to do with some security settings automatically updated on my machine (McAffee)? Just speculating.

Does thunderbird keep a log file (it may indicate exactly where the problem is)?
FWIW port 465 is working for me:

The server responses suggest it's a problem GMX's side.
