Hello,
I have one machine doing packet forwarding, nat and smtpd.
I have two internet providers and I want to receive mails on em2 and send mails
on em1.
dotbit# uname -a
OpenBSD dotbit.ro 6.5 GENERIC.MP#3 amd64
I receive on em2 with no problems using the following:
listen on em2 port 25 tag EXT
match tag EXT for domain <domains> from any action "deliver_local"
but I seem to fail to send from em1:
action "relay" relay src "86.34.153.250"
dotbit# ifconfig em1
em1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
lladdr 0c:c4:7a:51:6d:c2

dotbit# ifconfig em2
em2: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
lladdr 0c:c4:7a:51:6d:c3

dotbit# route -n show|grep default
default 109.166.210.9 UGS 12 3936306 - 8 em2
default 86.34.153.249 UGS 0 0 - 12 em1
Note: The em1 route has lower priority.
If I send an e-mail using this setup to gmail I receive an e-mail from ip
109.166.210.10 (em2)
If I have a "pass out on em1" and send mail using the above setup I get:
Aug 13 07:54:24 dotbit smtpd[15641]: ee7e33319534dd82 mta connecting
address=smtp://98.137.159.26:25 host=mta-v42.mail.vip.ne1.yahoo.com
Aug 13 07:54:24 dotbit smtpd[15641]: ee7e33319534dd82 mta error
reason=Connection failed: Permission denied
Aug 13 07:54:24 dotbit smtpd[15641]: smtp-out: Disabling route 86.34.153.250
<-> 98.137.159.26 (mta-v42.mail.vip.ne1.yahoo.com) for 15s
but it I also have "pass out on em2" the mail gets sent from em2
(109.166.210.10).
I do not need a solution for me personally, bit I think it should be possible
to chose where to send from.
I only need this is temporary fix until my new provider assigns me reverse dns,
then I can send and receive from the same route.
Thanks for smtpd, Dimitrios
