Redirecting wildcard email to one email with postfix
Solution 1:
As have said mschuett, you can use regexp
First check that postfix supports regexp:
root @ mail / # postconf-m | grep regexp
regexp
root @ mail / #
Create the file /etc/postfix/aliases-regexp and add to it your regexp
root @ mail / # cat /etc/postfix/aliases-regexp
/notification-message-[0-9]+@example\.net/ [email protected]
root @ mail / #
Run postmap and check whether it works:
root @ mail / # postmap /etc/postfix/aliases-regexp
root @ mail / # postmap -q [email protected] regexp:/etc/postfix/aliases-regexp
[email protected]
root @ mail / #
If everything is OK, add this file to your alias database
Example:
root @ mail / # cat /etc/postfix/main.cf | grep ^alias_maps
alias_maps = hash:/etc/aliases regexp:/etc/postfix/aliases-regexp
root @ mail / #
If you are using virtual domains, add this file to your virtual_alias_maps
Example:
root @ mail / # cat /etc/postfix/main.cf | grep ^virtual_alias_maps
virtual_alias_maps = mysql:/etc/postfix/mysql/alias.conf regexp:/etc/postfix/aliases-regexp
root @ mail / #
Do not forget to restart postfix.
Good luck!
Solution 2:
Alias maps (virtual, local, ...) will work in combination with the regexp_table format. But if you have compiled in PCRE, then you can also use the pcre_table format.
Otherwise you should search for "Postfix catch-all" which is a bit more greedy.
Solution 3:
I'd be inclined to solve this using recipient_delimiter
.
If you don't mind using slightly different Reply-To
addresses, you can set:
recipient_delimiter = +
in your config, and then mail to e.g. [email protected]
(note the +
) will be delivered to the notification
user (assuming there are no more-specific rules/users matching notification+message-988742
).
You could try setting recipient_delimiter = -
(so that you could use the Reply-To
headers as they are in the question) but I'm not sure how that would work with multiple instances of the delimiter on the left-hand side, and I don't have a Postfix to hand to check.
