yes, the directory defintely exists, but I think your hints are
already leading me into the right direction. It seems that the
problem is defintely been caused by insufficient access rights.
1. The access rights of the users home and all sub directories
are 0700, owned by the user, by default. The exim user, under
which the daemon is running, therefore cannot access the
directory.
# ls -ld /home/tom /home/tom/.imapmail /home/tom/.imapmail/cur
drwx------ 13 tom users 12288 Oct 10 01:47 /home/tom
drwx------ 12 tom users 4096 Oct 10 01:47 /home/tom/.imapmail
drwx------ 2 tom users 4096 Sep 23 19:18 /home/tom/.imapmail/cur
For testing purposes I changed the access right to 0701 and the
condition doesn't run into an error anymore.
2. Nevertheless I questioned myself why the same check is working
as expected on another server but not on this one. I found out,
that if I send an email from a local user to another local user
WITHOUT sender authentication the condition check fails:
20475 --------> localuser_maildir router <--------
20475 local_part=tom domain=my-domain.dom
20475 checking for local user
20475 seeking password data for user "tom": cache not available
20475 getpwnam() succeeded uid=2001 gid=100
20475 checking "condition" "${if exists{$home/.imapmail/cur}}"...
20475 ╭considering: ${if exists{$home/.imapmail/cur}}
20475 ╭considering: $home/.imapmail/cur}}
20475 ├──expanding: $home/.imapmail/cur
20475 ╰─────result: /home/dumbo/.imapmail/cur
20475 ├──condition: exists{$home/.imapmail/cur}
20475 ├─────result: false
20475 ├──expanding: ${if exists{$home/.imapmail/cur}}
20475 ╰─────result:
20475 localuser_maildir router skipped: condition failure # <<<!!!
20475 --------> unknown_user router <--------
3. If I send an email from a local user to another local user
WITH sender authentication the condition check succeeds:
17647 --------> localuser_maildir router <--------
17647 local_part=tom domain=my-domain.dom
17647 checking for local user
17647 seeking password data for user "tom": cache not available
17647 getpwnam() succeeded uid=2001 gid=100
17647 checking "condition" "${if exists{$home/.imapmail/cur}}"...
17647 ╭considering: ${if exists{$home/.imapmail/cur}}

17647 localuser_maildir router called for tom@???
17647 ...
My conclusion is, that although the check_local_user function is called
and the local user is found (getpwnam() succeeded uid=2001 gid=100) and
the $home variable is set correctly, the access priviliges are not
changed for the following exists command which results in a condition
failure.
I've also tried to replaced the "condition" by a "require_files"
statement, but this doesn't work either. So it seems that there is
no way to use this condition check in combination with an
unauthenticated delivery, except I would alter the directory access
rights.
