Hi:
I am hoping I can ask for suggestions or pointers to help solve this
challenge.
I am trying to implement an autoreply capability. I am putting
together a script that will handle the messages.
Many of the autoreply examples I've found suggest implementing this by:
main.cf:
always_bcc = autoreply
local_alias_maps:
autoreply '|/path/to/autoreply/script'
effectively causing all mail sent to anyone to be bcc'ed to the
script, which then determines if an autoreply needs to be sent. This
also ensures that delivery to the intended recipient (in my case, they
are all virtual mailboxes) will also happen.
However, as I started to test this, I discovered a limitation that I
am having difficulty finding a solution for. The scenario is that one
user on one domain that I host sends mail to another user at another
domain that I host. The recipient has autoreply "turned on" in my
script. However, according to http://www.postfix.com/ADDRESS_REWRITING_README.html
:
"To avoid mailer loops, automatic BCC recipients are not generated for
mail that Postfix forwards internally"
and the actual behavior matches that statement.
So my question:
Is there another mechanism I can use to send the mail to the script
without interfering with normal mail delivery in all cases , including
this internally forwarded mail?
Or, is there another way to handle autoreplies that anyone can suggest
or point me to that avoids this issue?
(I don't want all mail forwarded to the script, as I do not want to -
and am not sufficiently proficient to - handle reinjection into
postfix and the associated handling of SMTP/LMTP protocol)
Thank you very much for any help or pointers you can offer!
