I'm running Fedora-24(beta)/KDE,
and sendmail/email (through KMail) is failing.
When I try to send email I get the warning "Failed to transmit message",
and journalctl has the entry
"sendmail.service: PID file /run/sendmail.pid not readable (yet?)
after start: No such file or directory".
I've checked, and sendmail.pid is in place:
[tim@william ~]$ sudo cat /run/sendmail.pid
/usr/sbin/sendmail -bd -q1h
Googling for the journalctl entry,
I see people have been encountering this problem for years.
But I haven't seen any solution suggested.
Several of the comments suggest that it is a systemd problem.
If anyone can offer advice, or even elucidation, I should be most grateful.
Ps I posted this to fedora.general,
and was advised to post it to fedora-testing.
When I sent it there I was advised (by Ed Greshko) to send it here,
since he thought it was a KMail problem,
rather than systemd.
I have no problem sending SMTP mail with Thunderbird and Evolution.
