[AMaViS-user] amavisd & Postfix alias: duplicate mails

Hi, all.

I found an non-expect effect while I use alias in Postfix.

I have two accounts and one alias:
- User: www@a.cn
- User: postmaster@a.cn
- Alias: all@a.cn

I sent mail to both 'www@a.cn' and 'all@a.cn', then user 'www@' will receive
duplicate mails.

How can i make user 'www@' receive only one copy?

I already have 'receive_override_options = no_address_mappings' in Postfix
main.cf.

This is inherent to how Postfix does its alias expansions.

You received a more thorough reply on the postfix-users ML.
