i am Using Kerio Mailserver with its Trial Period. I am not sure, if i could handle what i am want to do with Kerio Mailserver.

Here is my Situation:
10-15 POP3 Account on gMail
4 Client without an Domain.
1 virtual Kerio Mailserver

Installed Kerio Mailserver, Domain: MyCompany.lan
Setting up the Relay server on /(want to send my Mails through this Mailserver)

If i send an Mail to XYZ<_a.t_> i get the following Message:
This is an informative message sent by vmail.lan.

The server was not able to deliver your email message

Subject: XXX
Date: Sun, 31 Aug 2008 18:58:58 +0200

to the following addresses:

<XYZ<_a.t_>> ( 550 5.1.8 <sashxp<_a.t_>mycompany.lan>: Sender address rejected: Domain not found)


ok, i understand. This comes, why my Mailprogram want to send Mail through - but i use an incompatible Domain Name. But if I use as Domain Name instead of mycompany.lan i can't Mail to other gMail Accounts.

Is this right?
How could i configure to use internal the Domain and be flexible? Is my plan impossible or am i just too stupid?

Sorry for my bad English,

this seems an odd solution but i think i understand you,

you can use the gmail domain as long as you set it to forward mail sent to recipients not it user list the the Gmail mx server (available from google)

however i cant see why you would want to do this

googlemail/gmail has a fairly good system already as it supports imap and has contacts and calendars also,

my real reccomendation would be to purchase a domain, they are generally cheap enough as it is, you leave the dns with the registrar and just set your server as one of the mx records
