Kmail 17.12 won't send smtp emails

[Skinjob2707]

Kmail recently stopped sending smtp based emails. Receiving pop3 works fine.

When I try and send, I get the following message (and a desktop notification) in the systemd log:

Code: Select all

Dec 21 12:20:22 generichostname plasmashell[2640]:  New Notification:  "E-Mail Sending Failed" "Failed to transport message. Server error" -1 & Part of: 0

I've tried rebuilding the kmail and kmailtransport packages to no avail. I've checked with Wireshark and the client is definitely making a successful TLS connection with the server. In the configuration, autodetect correctly identifies the settings.

Anyone have any ideas about what to try next?

Skinjob2707,

You can talk to mail servers with telnet.
Where does it break?

I did see that issue, but was led astray by the versioning numbers. When I look at help-> about there was no version number and the kmail package is listed as 17.12.0. When I switch to TLS (from SSL that was autodetected), I get an error message that says:

Code: Select all

New Notification:  "E-Mail Sending Failed" "Failed to transport message. 6" -1 & Part of: 0

Presumably this is the result of the server not supporting TLS.

I will follow the bug in the KDE tracker.

Thanks for the help!

FWIW, I got this "server error" message and found that kmail had
reset the smtp port to the wrong number

After updating to KMail 17.12.3 breaks sending email with SSL encryption. Unencrypted sending works.
