Description David Jarvie 2021-08-17 08:41:58 UTC

I configured KMail in a new system installation, to use sendmail to send mails. However, mails failed to send until after a system restart.

1. Install and configure postfix as a sendmail mechanism. I tested that this was working by successfully sending emails via the command line.

2. Use KMail's settings dialog (Accounts section, Sending tab) to set up a sendmail transport. This was the first and only sending method which I configured.

Attempting to send emails using KMail always failed. They just remained in the outbox. No error messages.

Using akonadiconsole, I restarted the Mail Dispatcher Agent. This made no difference.

Following a system restart overnight, mails now send successfully.


It should not require a system restart in order for this configuration to start working. Whatever it was that needed to be reset by a system restart should automatically be done without user intervention, as soon as a sendmail transport is configured by the user.

This wasted quite a bit of time investigating the issue yesterday. This bug might prompt some people to abandon their attempt to use sendmail and switch to another method.
