Hello all,
I am trying to get my vacation messages to work correctly. In general it
works like how I want, and replies when a message is arived to for
example i...@domain.com, but I have some problems to get my vacation
message to work on catch-all boxes. Is there an option to for example
auto-reply on every mail that is sendto @domain.com?
As stated by Pascal, catch-all addresses are evil. Especially when the
spammers do a dictionary attack run against your domain (you'll get
messages for a...@example.com, a...@example.com, a...@example.com...).
In our setup, we specify multiple addresses as:
:addresses ["na...@example.com", "na...@example.com", "na...@example.com"]
(For the few people that we allow inbound mail via multiple aliases.)
I understand the desire to have a catch-all address, I used to do it
myself a few years ago. But the aggravation eventually caused me to
reevaluate whether it was worth all of the dictionary attack spam. So I
setup aliases in postfix for all of the addresses that I was truly
interested in monitoring and simply "5xx unknown user" the rest of them.
