Hello, I have been developing a web application using ROR (hosted on webricks/windows) which makes use of ActionMailer to send out mails to various mailing lists. Recently, we came across a use case which required that a particular user belonging to a mailing list should not be sent out the mails. He cannot be removed from the mailing list either. So I devised something like a negative subscriber list, where we remove the user after expanding the mailing lists. The downside here was that ‘outlook-client’ specific rules started breaking for other members of the mailing-list. I came to know that Actionmailer supports envelope viz., ‘‘Return-Path’’ header for reply-to component of e-mail. I was wondering if there is any way that we can specify such envelopes for TO and CC fields too. I’m looking for something like what we have in sendmail of unix, $sendmail removed\_email\_address@domain.invalid From:removed\_email\_address@domain.invalid To: removed\_email\_address@domain.invalid Subject: Test Hellows… $ Any help would be of immense help to me. Please do let me know if you require any other information from my end. Regards, Shankar. ---

In your mailer, set @headers = {‘return-path’ =\> ‘removed\_email\_address@domain.invalid’, …} Fred ---

I had tried doing this with something like @cc = [“removed\_email\_address@domain.invalid”,“removed\_email\_address@domain.invalid”] . . @headers = {‘cc’ =\> ‘removed\_email\_address@domain.invalid’} The mails actually went through to removed\_email\_address@domain.invalid where as I wanted them to go only to removed\_email\_address@domain.invalid, removed\_email\_address@domain.invalid. Please let me know if I am missing something gross here. Regards, Shankar. ---

If I understand this right, once we set the header fields, they would be ones to which the mails will be sent. What I want is something like sendmail where the recipients are different from what is indicated by the headers… I’ll put it this way… x,y ,z are members of the list ‘foo’ and: @cc = [“removed\_email\_address@domain.invalid”,“removed\_email\_address@domain.invalid”,“removed\_email\_address@domain.invalid”] Here z should not be sent a mail, and the cc fields for the mails sent to x and y should still read the cc fields as ‘foo’. ~Shankar. ---

Please correct me if I am missing something. Thanks so much for all your help on this. ~Shankar.
