I don't really understand why people love so mush auto-responders, especially business people. These messages add a considerable amount of useless noise in our mailboxes. Even though I dislike those emails, it doesn't prevent companies or friends I am hosting on my servers to request them.
One of those companies is closing during the holidays. They wanted to have a vacation message sent whenever someone tried to contact them during this period.
They wanted to have a single vacation message for the entire company instead of asking each employee to set his or her own vacation message for each account.
Here is the solution I have used to do this.
Router
virtual_vacation:
domains = +virt_domains
driver = accept
require_files = /space/hosting/${domain}/vacation.msg
transport = virtual_vacation_trans
condition = ${if or { \
{match {$h_precedence:} {(?i)junk|bulk|list}} \
{eq {$sender_address} {}} \
} {no} {yes}}
# do not reply to errors or bounces or lists
senders = ! ^.*-request@.*: ! ^bounce-.*@.*: ! ^.*-bounce@.*: ! ^owner-.*@.*:\
! ^postmaster@.*: ! ^webmaster@.*: ! ^listmaster@.*: ! ^mailer-daemon@.*:\
! ^root@.*: ! ^abuse@.*
unseen
no_verify

unseen
no_verify
The router checks if the file
message.msg exists in the home for that domain.
The router also tries to determine if the mail is coming from a mailing list or if it was auto-generatd. We don't want to send the vacation message to these addresses.
Transport
virtual_vacation_trans:
driver = autoreply
to = ${sender_address}
from = "do_not_reply@${domain}"
file = /space/hosting/${domain}/vacation.msg
once = /var/tmp/vacation_${domain}.db
once_repeat = 7d
subject = "Re: Away for holidays / En vacances - ${local_part}@${domain}"
virtual_vacation_trans:
driver = autoreply
to = ${sender_address}
from = "do_not_reply@${domain}"
file = /space/hosting/${domain}/vacation.msg
once = /var/tmp/vacation_${domain}.db
once_repeat = 7d
subject = "Re: Away for holidays / En vacances - ${local_part}@${domain}"
The transport is pretty straightforward. It sets the
to,
from, and
subject as well as the content of the mail extracted from the file
vacation.msg. The email addresses of the senders are kept into the file
vacation${domain}.db, in order to send the vacation message only once a week. Determined by
once_repeat = 7d.
