Bug ID: 452825 Summary: "Request delivery confirmation" not working Product: kmail2 Version: 5.19.2 Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: kdepim-b...@kde.org Reporter: samuele.zapp...@mail.com Target Milestone: --- Created attachment 148282 --> https://bugs.kde.org/attachment.cgi?id=148282&action=edit Screenshot of the sources of the messages. SUMMARY Every time I try to send an email requesting delivery confirmation the email isn't sent and I receive a notification that says: "Failed to transport message. Server error: Syntax error in parameters or arguments" STEPS TO REPRODUCE 1. Write a new mail message 2. Select the option to request a delivery confirmation under Options > Request delivery confirmation 3. Look at the outcome OBSERVED RESULT Instead of simply sending the mail with the request, I get an error. EXPECTED RESULT It should send the email with the request annexed. SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Neon 5.24 KDE Plasma Version: 5.24.4 KDE Frameworks Version: 5.93.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION The SMTP account I'm using to send emails is set to store the password and uses the SSL/TLS port 465 with PLAIN authentication. The issue appears also with STARTTLS port 587. This happens with a @mail.com account and not with a @gmail.com account, but with the latter I still don't receive the confirmations. I inspected the sources of the two messages, the one I tried to sent with @mail.com (and was never sent) and the one sent with @gmail.com (that was actually sent). I thought that such "syntax error" could be seen from the source. I see that they are very different. -- You are receiving this mail because: You are watching all bug changes.
