Redirect outbound mail based on from address

From: Barney Barumba on 2 Nov 2009 07:33 Hi, I'm trying to redirect outbound mail based on the from address. I've seen a few things that say sender based routing is not supported, but I'm not sure if that is what I need or not. The problem is that I want to use my local mail client to send mail from my work address, which is running MS Exchange. I don't want to simply replace the from address on the outbound email - I want to actually have the mail sent from the Exchange server. The only external access to this server is via WebDav, so I've written a client that accepts an email message from its standard input, logs on to the server, and sends the message. All I need to do now is configure my postfix server to pipe selected messages to this client (or better still, to maildrop which can also store a local copy). Ideally, all I'd like to do is select my work address as the from address in my original message and have the server do the rest. Is this possible? Or is there any other way of routing selected outbound messages to a local program? Thanks, Barney

Postfix has: http://www.postfix.org/SOHO_README.html#client_sasl_sender which selects a per-sender next-hop address, when the recipient is remote (delivered via SMTP). Choosing per-sender transports has no reasonable semantics when some recipients are local and some remote. This feature is not offered. > The problem is that I want to use my local mail client to send mail from my > work address, which is running MS Exchange.

If you turn your submission script into a local SMTP service, or deploy a Postfix smtpd(8) on an alternate port with content_filter set to your script, you can cause mail to remote recipients and the appropriate sender address to flow through your script. -- Viktor.
