I have strange thing,

I found that some mails sends by logcheck are delayed.
After some digging I found that:

--8<---------------cut here---------------start------------->8---
echo bla |sudo -u logcheck mail root
--8<---------------cut here---------------end--------------->8---

makes this error:
--8<---------------cut here---------------start------------->8---
2022-06-06 20:30:26.225 [517397] 1nyHUg-002Ab7-5a <= [email protected] 
U=logcheck P=local S=432 M8S=0 RT=0.040s id*[email protected] from 
<[email protected]> for root
2022-06-06 20:30:26.247 [517398] 1nyHUg-002Ab7-5a == [email protected] 
<[email protected]> R=dovecot T=dovecot_pipe defer (0) DT=0.004s: Failed to 
create child process for dovecot_pipe transport: Resource temporarily 
unavailable
--8<---------------cut here---------------end--------------->8---
and message ends in queue, and then is delivered later.

relevant records from /etc/aliases

root: kjonca
logcheck: root

When I try:
--8<---------------cut here---------------start------------->8---
echo bla |sudo mail root
--8<---------------cut here---------------end--------------->8---
there is no such error.

When I configure to deliver without pipe - everything works.

So I believe something is misconfigured (suid/ownership/groups?) but I
do not know how to debug it.

Any ideas what to check?
