I solved it! For the others that have same problems:

Its an windows routing problem... For each IP Windows adds an default route. To see type in CMD: "nestat -rn"

Windows takes the route with the smallest "cost", the metric value. By default all 3 default routes have the same

metric and the second route is taken by random. Now i changed the metric of the route with the wanted outgoing IP -1.

(Before: 256, Now: 255) An nice tool for changing the routes ist "NetRouteView" for Windows. Now everything works! :)

Thanks dilbert_left_nut!

Hi everybody,

i tried to understand the posts before but i did not. I only want to use my working mercury server install with several domains.
I have one server with one licenced mercury install. This one Server have 3 IPs that I all use for MX Records.

So is this setting correct??

[Domains]
liktor: liktor
liktor: localhost
liktor: maindomain.de
liktor: [85.88.13.39]
liktor: [85.88.13.129]
liktor: [78.111.72.209]
liktor: domain2.de
liktor: domain3.de
liktor: domain4.de

Thanks Michael

yes [:)]

Thanks... But... :)

 I get some strange Header things... I send an Email from an user of domain1.de but
in the receive information I get an Received from domain2.de and EHLO maindomain.de
maindomain.de is okay I think but I dont know why i get domain2 in an domain1 email?

So I think there must be an configuration problem... :( Any idea?

Thanks Michael

Well it looks like you have 'maindomain.de' as the 'internet name for this system' and/or 'announce myself as' in MercS.

The "Recieved from: domain2.de" is added by the GMX server after doing a reverse lookup on your connecting ip address.

If you want different configurations for each sending domain you will need to run seperate instances of Mercury.

Okay, so the domain2.de ist because of the PTR of the connection IP (85.88.13.129)? Thats right, thats setted!

But why is domain2.de`s IP the connection IP ? Thats not correct! I have 3 IPs and I always want to take maindomain.de
(PTR setted to 85.88.13.39) for connections (OR the correct emailsenders domain1.de`s IP (From: xxx@domain1.de))
but NOT the IP and domain2.de of another client. Where do I have to configure that?

In windows I suspect.

I'm not able to check Merc (quickly) at the moment, but I don't recall being able to bind the MercE client to a specific interface, unlike the server modules.

I think it just asks windows for an outgoing connection.

You may have to fiddle with the routing table (metrics etc.) to set your preferred interface as the default.

Mhmm... so you are right, it seems that Mercury binds to the wrong IP... is there non possibility to do that?

I checked windows and this wrong ip is not setted as first and not at last, so it doesnt make sense to choose that.

I MercuryE there is the setting "identify myself as"... is that an chance? Or set the IP here with [right_IP]?
