Hi guys,
I'm chasing my tail on this one. The setup is pretty simple virtual
hosting, with virtual_alias_maps in a file 'virtuals' which works fine,
except for one line:
b...@example.com bob, john, dave
When sending a mail to b...@example.com, bob receives one copy of the
mail, but john and dave each receives two. I understand the problem:
postfix does the recipient expansion, sends it off to spamassassin.
Spamassassin requeues the mail via the sendmail binary, so postfix
treats it as a new mail.
The log goes something like this (I separated the before and after parts
for easier reading):

I tried setting receive_override_options = no_address_mappings but this
kills address expansion both before and after filtering. Is there a
way to disable it only on one side of the content_filter?
Config is included at the bottom.
Thanks
