Hello. I'm using Exim for virtual domains mail with system accounts.
I have a cron script that checks quota usage every minute and creates a current list of system users that went X MB over softquota limit for more then Y days. This is a simple file with each username in new line: cat /etc/mail/blocked_because_mailboxisfull jsmith jsmith2 What I'd like to do is to motivate these users to clean up their mailbox (and also prevent disk usage to grow up to hardquota limit) by: a) disabling sending new mail by that users b) bouncing incoming mail for that users (ie for: [email protected], etc) That should be quite easy but it turned out my rules don't work as expected so I need some help with that. Ad. a) - disable send --------------------- I've added additional rule to acl_smtp_rcpt chain that will deny SMTP for authenticating users, who are in the "blacklist": deny message = Sending prohibited, your mailbox is full condition = ${if \ ${lookup{$authenticated_id} \ lsearch{/etc/mail/blocked_because_mailboxisfull}}{1}{0}} authenticated = * But it doesn't work. It logs a failed to expand ACL string, condition name expected (?). Q1: How should the condition look like to be correct? Q2: Is such a rule and a place for that rule (acl_smtp_rcpt, quite high, before many other checks) optimal for per-user SMTP prohibition? Ad. b) - bounce incoming mail ----------------------------- I'm not sure where this sould be checked. Q3: If possible during RCPT? That would be perfect, but do I have e-mail address to system username relation then? If not, it's OK for me to accept the message and bounce it before local delivery. I'm not good at writing routers, but I've tried adding such: useroverquota: driver = redirect local_parts = lsearch;/etc/mail/blocked_because_mailboxisfull data = :fail: User mailbox is full allow_fail just before: localuser: driver = accept transport = local_delivery [...] And this doesn't work either. Q4: How this should be done to work as expected? Thanks in advance for any help.
