Hi,
after several hours trying to get it to work without success I admit I
should have posted a copy of the current Exim configuration at first
place;-)
Our setup is a bit more advanced like I originally stated.
Normal inbox: $HOME/.imap_mail/inbox
User can optionally enable a spam check of incoming mails.
Exim router: user_SPAMscan, require_files = ${home}/.mta_spamscan
If $HOME/.mta_spamscan exists, the mail is scanned, tags with the result
added and the mail stored in normal inbox.
Exim router: user_SPAMstore, require_files = ${home}/.mta_spamstore
If $HOME/.mta_spamstore exists, the mail is scanned, tags with the
result added and spam mails are stored in $HOME/.imap_mail/Spam.
Non-spam is stored in normal inbox.
Same is valid for virus scanning:
Exim router: user_VIRUSscan, require_files = ${home}/.mta_virusscan
If $HOME/.mta_virusscan exists, the mail is scanned, tags with the
result added and the mail stored in normal inbox.
Exim router: user_VIRUSstore, require_files = ${home}/.mta_virusstore
If $HOME/.mta_virusstore exists, the mail is scanned, tags with the
result added and virus mails are stored in $HOME/.imap_mail/Virus.
Non-spam is stored in normal inbox.
Exim router user_VIRUSandSPAMscan to do a combined spam+virus scan also
exists, but it works the same way as described above.
Scanning takes place by using external scripts (not my design choice,
but I do not like to change a running system) and re-injecting the
resulting mail using
/usr/sbin/sendmail -f "${SENDER}" "${RECIPIENT}" < ${TMPFILE}
During my tests a virus/spam check did not take place (confirmed by exim
-d -v), so spam+virus checks should IMHO not be the source of my
problems, at least at the moment...
In an over-quota situation all mails should be written to
/var/mail/$user to avoid bounces, so users lose the function to keep
their inbox clean of spam and viruses. But thats their own fault;-)
Providing spam/virus checks + storing positives outside inbox is the
reason I am not able to store all incoming mails to /var/mail/$user.
Another idea would be to store spam in /var/mail/$user.spam and virus
mails in /var/mail/$user.virus, but my IMAP server (uw-imap like
snarfing-patched Dovecot) is only able to snarf one IMAP mailbox per user.
Now I tried to implement your idea to use condition first_delivery to
deliver to /var/mail/$user after the first deliver attempt failed but it
does not work, bounce mails are still produced. Weirdly enough in rare
cases a mail to an over-quota user hit /var/mail/$user, but only after
restarting Exim when a mail was in queued state. But I do not know why
this happens only when restarting Exim and not during normal usage.
I will therefore post the routers, transports and retry sections of my
exim config file in the hope that someone can point me to the error.
All first_delivery settings were added today, are completely without any
effect, Exim behaves like being used without it. The quota entry in the
retry section, the router user_var_mail and the transport inbox_var_mail
were also added today.
Greetings and thanks in advance, Bernd Kuhls
