Alias pipe to program


Is it possible to forward messages intended for a particular email to the standard input of a program. With postfix this would be handled through an alias that pipes into the program.

Something like this
add line into file: /etc/aliases

issues: "|/usr/local/sbin/mailhandler"


I have the same question. it did not work in my case.


I got it to work by changing mydestination on but then no other emails were working.

I tried to have both and localhost on $mydestination but that made other emails useless.

don’t think virtual_mailbox_maps virtual_alias_maps can pipe into a program. any idea how can I achieve this?

now I’m thinking to have a separate email server just to pipe emails into a script (which is a stupid workaround).

UPDATE: apparently sieve has a plugin called extprogram that does what I need. but did not manage to get it to work


Has anyone had any luck with this

I am trying to pipe an email alias to a php file for some processing

I can get this done through /etc/aliases but cannot work out how to route an email from mailinabox to one of the local accounts so it can be automatically piped to my php script
