I'm guessing my obfuscation has clouded the issue, so I'll re-iterate my question with (hopefully) a clearer example.
We need three email addresses that go to our domain (in this example referred to as my-domain.com) @my-domain.com, to be redirected to @other-domain.com. These three users do not exist on our systems. The postfix server relays mail directly to an exchange server, apart from three exceptions that are delivered locally. (but that is irrelevant for this query) So, for the three addresses, redirection should be as follows: us...@my-domain.com -> us...@other-domain.com us...@my-domain.com -> us...@other-domain.com us...@my-domain.com -> us...@other-domain.com All other email for @my-domain.com is relayed to an exchange server (with two or three exceptions as described above) So... In /etc/postfix/virtual - I have: anythinghere.com VIRTUALDOMAIN # this is as per the postfix readme # redirects to other-domain.com us...@my-domain.com us...@other-domain.com us...@my-domain.com us...@other-domain.com us...@my-domain.com us...@other-domain.com ----------------------------------------------- In /etc/postfix/transport - I have: # these addresses delivered locally # my_us...@my-domain.com local: my_us...@my-domain.com local: my_us...@my-domain.com local: # my-domain.com smtp:[1.2.3.4] # 1.2.3.4 is the exchange server # ------------------------------------------------------------------ In /etc/postfix/main.cf - I have: # virtual_alias_maps = hash:/etc/postfix/virtual # I also have a virtual.db in /etc/postfix - generated with postmap. -------------------------------------------------------------- I am using spamassassin to filter mail - so mail is delivered to spamassassin and then passed back to postfix for delivery. (hence the relay=spamassassin) This is the log entry generated when sending email to us...@my-domain.com Dec 4 12:22:40 my_server_name postfix/pipe[7162]: A973D9170E: to=<us...@other-domain.com>, orig_to=<us...@my-domain.com>, relay=spamassassin, delay=3, status=sent (my_server_name) However - the person on the receiving end doesn't get the email - it appears to end up in some administrator mailbox (not much detail - and I haven't been able to get more) - which suggests an over zealous spam filter on their side. So I'm wondering if the address rewrite is triggering some kind of anti spam action on the (other-domain.com) server - and hence begs the question - am I doing this correctly? I have tested this to my own home account *and* to Hotmail (by setting up the appropriate redirects) and it worked fine in both cases. So my question is: ------------------ Have I done this correctly? I looked on the postfix site and various man pages - and picked up a hint that perhaps I should be using canonical for this - but I'm not sure.... I hope this example is clearer - and apologies for the length of it.

I've done similar here with a transport map. transport_maps = hash:/etc/postfix/transport :transport: f...@example.com local: example.com smtp:[nameofsmtpserverforexample.com] And then used /etc/aliases to redirect "fred" email to whereever I wanted it to go - but I know our destination doesn't use SPF, or any "silly" spam checks. Crude but it works for our needs. > Dec 4 12:22:40 my_server_name postfix/pipe[7162]: A973D9170E: > to=<u...@bloggs.com>, orig_to=<u...@example.com>, relay=spamassassin, > delay=3, status=sent (my_server_name) spamassassin - who is this server? > However - the person on the receiving end doesn't get the email - it > appears to end up in some administrator mailbox (not much detail - and I > haven't been able to get more) - which suggests an over zealous spam > filter on their side. I think you are going to have to explain the set up more, or provide the normally requested output for this list. > So my question is: > ------------------ > > Have I done this correctly? It feels wrong to me, how does postfix know what to do with the rest of example.com's mail. Or has your obfuscation destroyed the question?
