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.
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
