Hi,

Just a guess, but it looks like you are being hit by a bug that was 
fixed starting with HTCondor v8.2.6 and above.  Specifically, this one:
 https://htcondor-wiki.cs.wisc.edu/index.cgi/tktview?tn=4764

My guess is HTCondor v8.2.3 is invoking mail with a "-f" command-line 
argument for the from address, like so
  /usr/bin/mail -s subject -f gitlab@xxxxxxxxxxxxxxxxxxxxxxxxx user@xxx
And my guess is /usr/bin/mail on Debian wants the from address via a 
"-r" argument because "-f" means something else.

If I guessed right, as a workaround you could get rid of the MAIL_FROM 
setting in your condor_config file(s), which should cause HTCondor 
v8.2.3 to omit the incorrect "-f" option all-together.  Or you could 
write your own wrapper script for /usr/bin/mail that converts the "-f" 
to "-r" and set MAIL in condor_config to point to it.
Or you could upgrade HTCondor to a more recent version where this issue 
has been fixed- recent versions are available packaged for Debian, see
 https://research.cs.wisc.edu/htcondor/debian/

Hope the above helps,
Todd
