autoresponder has stopped working

[eugenevdm]

It could also be that the autoresponder has never worked. Here is the ".qmail" file contents:

| /usr/bin/odeiavir
| /usr/bin/spamc -f -u [email protected] -U /tmp/spamd_full.sock | /usr/bin/maildir ./Maildir/
| /usr/bin/sguardstat [email protected] 0
|autoresponder
| true

I see no further information in the /var/log/mail.info file.

Something I do notice however is a lot of "warning: trouble injecting bounce message, will try later" but hopefully this is unrelated.

Does anyone have tips how to troubleshoot the problem?
