Make tools-mail route mail for @tools-*.pmtpa.wmflabs correctly
Closed, ResolvedPublic


Small script I use currently to reroute stuck mail.

From time to time, there are hiccups in cron or wherever and mail gets sent to $user@tools-login.pmtpa.wmflabs et al. These stew in tools-mail:

tools-mail: 34m 2.1K 1WFiPT-00027M-9N <>
tools-mail: local-theoslittlebot@tools-login.pmtpa.wmflabs

because tools-login has no SMTP service listening, and if it had, it would probably create a loop :-).

I use a small script (attached) to reroute such mail, but I don't want to any longer.

tools-mail should, as the mail relay for Tools, accept such mail as its own and process it as if it has been sent to $

So assuming tools-bastion-01 is arbitrary, tools-mail would need to have a list of all Toolforge instances? Because in this case, the mail was submitted on tools-webgrid-lighttpd-1201 so it's not just that the local hostname gets (incorrectly) appended. With the new DNS structure, the check could be reduced to *.tools.eqiad.wmflabs, but these "extended" hostnames do not appear in the mail addresses. Hmmm.

And /etc/mailname on tools-bastion-01 is (correctly):

scfc@tools-bastion-01:~$ cat /etc/mailname

Maybe gridengine uses the old hostnames and we need to switch it to the new scheme first?

Rereading the man page for mailname, of course the other approach to try would be to set /etc/mailname to and see what happens. Issues to look out for:

  • Is /etc/mailname only used to qualify mail addresses or (mis)used by a sending/receiving exim to identify itself?

I set /etc/mailname to, restarted gridengine-master, submitted a job on toolsbeta-master and qstat -j 4 still gave:

mail_list:                  scfc@toolsbeta-master.toolsbeta.eqiad.wmflabs

So this path is not a viable solution.

Change 237863 had a related patch set uploaded (by Tim Landscheidt):
Tools: Accept mail for all submit hosts

Change 237863 merged by Yuvipanda:
Tools: Accept mail for all submit hosts

Tested this by qsub -m e -b y sleep 60 on tools-bastion-01 and while:

scfc@tools-bastion-01:~$ qstat -j 408481
mail_list:                  scfc@tools-bastion-01.eqiad.wmflabs

the message was successfully delivered to me.
