When you say routed mode in your vpn, are you using the same
ip address ranges in your two lans, or do they have
different ranges?
I guess my understanding of the smtp proxy is wrong. I
thought it captured all smtp traffic going out in order to
pass it thru the AV, etc. In your setup, I would disable the
smtp proxy completely. But again, maybe my understanding of
what the efw smtp proxy is capable of isn't complete...

Subject: [Efw-user] SMTP Proxy Connection refused
Hello,
I am using two Endians 2.1.2 in two cities (let's give them
name A and B), both location are connected via OpenVPN
Net-to-Net. And there is one MS Exchange 2003 as a backend
server in city B. The are two different networks, VPN is in
routed mode (not in bridged) so the endians are responsible
for routing between both LANs
My problem applies to SMTP Forwarding via VPN. (SMTP Proxy +
Exchange = Conection refused)
In City A, Endian_A (it is the mx0 ) take incoming email
traffic and forward direct to MS_Exch2k3_B in city B.
In City B, Endian_B (it is the mx1 ) the Endian_B should
take care about email forwarding to MS_Exch2k3_B, only in
case when the mx0 in city A is offline. (It works)
I've set at Endian_A (Proxy->SMTP->Domains) for my domain a
local ip from MS_Exch2k3_B, important fact is that, Endian_A
and MS_Exch_2k3_B are in different LANs. With the same
setting on Endian_B works everything fine, but only in case
when Endian_A is offline (the sequence of mx entries by
domain provider is so defined, and change of this settings
can not be treat as a solution)
On the MS_Exch_2k3_B (Exchange->Global Settings-> Message
Deliver ->General) I've added extra entry for Endian_A.
In logs at Endian_A is following :
postfix/smtp[3908]: 846A922DD2F: to=, relay=none, delay=0,
status=deferred (connect to MS_Exch2k3_B(ip) :Connection
refused)postfix/smtp[3908]: connect to MS_Exch2k3_B(ip) :
Connection refused (port 25)
On MS_Exch2k3_B is nothing to find in logs.
Could someone write me why it doesn't work, and how to solve
this problem?
Thanks in advance
Best regards
Rafal Sladek
