how to configure virtual smtp, server has horde, unable to send from external client

peter.law...@glendiscovery.co.uk — Mon, 15 Apr 2013 11:09:02 UT

Hi
I have set up a RedHat 6 server with Horde 5, it works correctly now (after much headscratching) for users using imp for their mail.
However, if using an external mail client (I have been testing with thunderbird 17.0.4) -
I can send and receive messages from horde / imp to users on external domains and also I can send mail from Thunderbird to imp users on the server but not beyond to the external domains as the server will not act as a relay

Conditional replace among e-mail header fields: possible?

netre...@netrelay.eu (Gabriele) — Mon, 15 Apr 2013 08:25:26 UT

Greetings,

I need to modify the "From:" header line in incoming e-mail messages ONLY IF "Message-Id:" starts with a defined string.

The action pattern would be similar to the following:

/^From: (.*)@johndoe.com/ REPLACE From: $...@ext.johndoe.com

Can you suggest a way to accomplish this?

sender address/domain rewrite problem

czora...@gmail.com — Wed, 03 Apr 2013 15:57:21 UT

Hi there,

I'm trying to rewrite sender address/domain from @sub.example-domain.com to @example-domain.com.

I tried:
1) masquerade_domains = example-domain.com
2) sender_canonical_maps=hash:/et c/postfix/sender_canonical
(sender_canonical: @sub.example-domain.com to @example-domain.com)

In both cases, with masquerade_domains and sender_canonical_maps, when I send a mail from u...@sub.example-domain.com, I recieve mail with:

From the view of outlook it looks like outlook doesn't do anything. Not even an error is shown. I think outlook even thinks the mail has been sent, but it will stay in the outbox and it wasn't sent.
