Ohh je, next trouple.

postfix installed runs great on localhost.. now we have a problem huston.

dns entry on a extern dns host.
mail.xxx.com IN MX 210.222.xxx.xxx

local Router:
194.xxx.xxx.xxx

Local Network:
192.xxx.xxx.xxx

Tryed to set under relay host (mail.xxx.xom)
and under proxy the gateway, and under inet_interface the gateway, and under both the mail.xxx.xom
and also the relay_host all 3 ip's.

But simple postfix refuses to accept mail.

Any Hint in what direction i could walk will really help.

Have you set mynetworks correctly?

Also, if you are relaying through mail.xxx.com, I think you only need to set

relayhost = mail.xxx.com

what are your settings for inet_interfaces, etc.

Where are you sending mail from? If you are sending from this box, you need localhost in inet_interfaces. Are you really wanting to relay for mail.xxx.com?

It would help if you posted the relevant sections on main.cf

oky..

mail to user@bla.com

dns entry on a extern dns host.
mail.bla.com IN MX 214.001.001.001

at my home.
Router on a DSL with a static IP
214.001.001.001

I gues MX need to point to my router.

Then NAT on the router what forwards port request on 25 to
192.168.178.2

On this box, linux runs. with Postfix. Apache and mysql. apache runs great, rest too, except that silly postfix

under - relay_host = mail.bla.com
inet_interface = '' nothing at the moment.

okay got it to work.. but somewhere i have a an error in the virtual tables..
As soon i uncoment them, conection get refused But it seems i can't figure it out.

even if i set it up like this it starts to refuse.

virtual_maps = hash:/etc/virtual

-- virtual file ---
test.com anything
-------------------------
tryed also via
-- virtual file ---
mail.test.com anything
-------------------------

Was the problem something to do with "mydestination"? I think you have a logical loop there.

Dumb question - you are converting the virtual file (it's either postmap or postalias, I don't use virtual maps myself).

www.postfix.org has great documentation on all this stuff

dunno.. if i use hash:/bla bla
it works
if i try to use mysql it dosent, but postconf -m shows mysql..
anyway, i can leave with hash: looks like or at least i have to

I guess you've looked at

http://www.postfix.org/MYSQL_README.html

but if not, here it is

yep.. postconf -m lists mysql as well.. so should be compiled in. the formats of the tables are correct also..
