Hello @ll
I have a little problem with postfix 2.5, trendmicro viruswall and an
old exchange 2k behind it. Perhaps somebody could give me a hint because
I'm really confused after some days of trying different things.
for incoming mail everything is clear:
relay_domains and transport_maps, tmvw as a content_filter do the job!
Internet DMZ Intranet
-------- --------- ----------
tmvw (as cf)
10025
^ |
| v 10026
smtp (25)-> pf (25)-> exchange2k
outgoing mail should be handled a litte different:
Internet DMZ Intranet
-------- --------- ----------
tmvw (as cf) <---- (10025)
| (10025) |
(10026)| ^ | not possible!
v | |
MX <-(25) pf pf-sec <-(25) ex2k
Because of the fact the ex2k was migrated from 5.5 we actually have the
problem that ex2k is not configurable to use any other port than 25.
This breaks the design of tmvw.
My idea is a second smtp-process (I have two IPs) like this
master.cf
192.168.1.3:25 inet n - n - - smtpd
192.168.1.4:25 inet n - n - - smtpd
What I want ist a forwarding process getting it's mail on port 25 and
forwarding it to port 10025 of tmvw. tmvw should reinject on port 10026
of the first (outbound) smtpd process .
What I think to know is that my second process has to have set this
192.168.1.4:25 inet n - n - - smtpd
-o myhostname=gw.mydomain.local
-o relayhost=smtp:[127.0.0.1]:10025
-o content_filter=
-o smtpd_use_tls=no
-o mynetworks=192.168.0.0/24
-o mydestination=
-o relay_transport=
Is this possible and why does it not forward to port 10025? Do you have
a source for me dealing with a similar problem?
The relayhost parameter is a property of trivial-rewrite, not
smtpd, and can't be controlled this way.
Use content_filter=smtp:[127.0.0.1]:10025 instead.
