Address Rewriting vs Aliasing - I need all recipients to see each other

2014-02-02 Thread Charles Marcus

Hi all,

I'm under the gun, and reading furiously, but I'm hoping someone will 
help point me in the right direction...


I want to set up an email alias for my domain, ie:

facilit...@example.com

That sends the email to two (or more) external addresses:

us...@example2.com
us...@example2.com

Currently, if I set up the alias, each recipient only sees themselves as 
the recipient, but I need all recipients to see each other, so each 
knows the other received it.


I would prefer they not see the original alias, but it isn't that important.

I'd also like for one the be added as 'To:', and the other as 'CC:', but 
again, not really that important, as long as they will each see the 
other got it.


I'm guessing I need to use Address Rewriting rather than just an alias, 
but I'm not sure which method or how to accomplish it.


Thanks,

Charles

Hi Charles,

 Currently, if I set up the alias, each recipient only sees
 themselves as the recipient, but I need all recipients to see each
 other, so each knows the other received it.

I do not quite understand that. Normally, when you use a simple alias,
no adresses are rewritten, so the original headers should be preserved -
resulting in all recipients seeing the alias rather than any of the
resulting addresses.

Maybe there are canonical rewrites in place somewhere already?

Cheers,
Nik

Thanks for the reply Dominik, but...

That is precisely what is happening with my normal alias - but as I said 
in my email, that is NOT what I want.


I WANT each recipient to see ALL of the other recipients (I honestly 
don't see how that was unclear)...


Also - why did I receive no less than three copies of your email? Please 
keep traffic on list, and I don't need to be CC'd, as I'm on the list.


Thanks again,

How's that done?  Generally, the message headers are unchanged and
all you see is the alias.  So not sure what you mean by only
sees themselves.

 but I need all recipients to see each
 other, so each knows the other received it.

s/received it/was another recipient/

 I'd also like for one the be added as 'To:', and the other as 'CC:',
 but again, not really that important, as long as they will each see
 the other got it.

They can't know the other recipient got the message, they can only
know that it was alleged to have been sent to the other recipient,
and for this it is sufficient for them to know that they're both
targets of the alias.  The requirement you have is rather strange,
it appears to be appeasing someone's confusion rather than enlightened
interest.

All that said, Postfix has no facilities for 1-to-many header
recipient rewriting.  This would need to be done via procmail
or other external filter.
