Hello,
I've a problem when I try to make a script autoreply for a user in postfix.
I think the problem is due to amavis, because I've made this:

When a mail is sent to thierry@linux.thierry.eu.org (which is a real user with a virtual mailbox), it's forwarded to itself, and to thierry@autoreply.linux.thierry.eu.org, which is used with the transport autoreply.

So the sender receives 2 times the autoreply script.

(this is the interesting lines of master.cf)

smtp inet n - - - - smtpd
smtp-amavis unix - - n - 2 lmtp -o lmtp_data_done_timeout=1200 -o lmtp_send_xforward_command=yes

127.0.0.1:10025 inet n - n - - smtpd -o content_filter= -o local_recipient_maps= -o relay_recipient_maps= -o smtpd_restriction_classes= -o smtpd_client_restrictions= -o smtpd_helo_restrictions= -o smtpd_sender_restrictions= -o smtpd_recipient_restrictions=permit_mynetworks,reject -o mynetworks=127.0.0.0/8 -o strict_rfc821_envelopes=yes -o smtpd_error_sleep_time=0 -o smtpd_soft_error_limit=1001 -o smtpd_hard_error_limit=1000
smtp unix - - - - - smtp
autoreply unix - n n - - pipe

maildrop unix - n n - - pipe

Thanks.

Have you got a solution for this?

I have the same issue, the auto responder is sending twice.
