I'm trying to figure out how to make procmail deliveries
more robust, by checking if the user's system quota is
exceeded, or nearing its limit.
As it is now, the message is handed over to procmail, which
discovers that there is no space available, so the message
is appended to /var/mail/<username> instead of begin
delivered to the user's Maildir folder. This has caused some
frustration, so we need a more robust solution.
My idea was to have a router with a condition that runs a
command to check for available space. If the condition is
true (there isn't enough space), the message is kept on
queue and retried at the usual intervals. Is that possible?
Or is there perhaps a better way to solve this?
Here is our router:
procmail:
driver = accept
check_local_user
transport = procmail_pipe
require_files = ${local_part}:+${home}/.procmailrc
no_verify
no_expn
And here is our transport:
procmail_pipe:
driver = pipe
command = /local/bin/procmail -d $local_part
return_path_add
delivery_date_add
envelope_to_add
check_string = "From "
escape_string = ">From "
user = $local_part
group = mail
log_fail_output
log_defer_output
return_fail_output
Thanks for any help.
