Mail server problem

[ritvi]

Hi guys,
I currently have Lotus Domino Mail server ( R6 ) and http server running on the same. My ip address is X.X.X.70 which is a live ip with a MX record.

My MX record is as below:

I want to install a new Mail server running on RHEL 3 ES with Postfix+MailScanner+ClamAV+spamassassin as described in your website. this mail server will have a live ip address 59.163.186.66. I want to keep both mail server running but only have 1 MX record on 59.163.186.70.

i have a user account deep in lotus domino Mail server, and i have a account vijay in Linux Post fix account. if a person sends a mail to vijay@kribhcosurat.com in that case which of my mail server would recieve the mail? if one of my server receives the mail but the user dose not exist on that server and exists on the other server wihat will happen to that mail?

Do i need one more MX records ? do i need another domain ???

MX record: I'd say yes, you need a secondary to make the Linux Postfix box able to receive mail.

I would make sure the users exist on both servers because if the user is on the Domino box and not the Linux box and the Linux box receives the mail, and it doesn't have the user it will reject the mail, not forward it to the Domino box.

In that very same scenario if there was a .forward record and a user, the mail could be pushed onto the Domino box.

Another domain would allow you the flexibility to have two user sets and not have mail rejected. I'm not sure its a requirement but it could provide you the flexibility you need to pull this off.

Yes SEP is correct .You need two MX records , if u r going to use both the servers online and both of the servers should have the users configured...
In case u r using sendmail in ur linux server ( i dont know about postfix ) u can have ur aliases configured in such a way that the mails will be forwared to the domino server , then there is no need of adding those users in ur linux box. But whether to configure this will depend on ur situation ..
BTW.. i am already getting two mx records for ur domain

Hey,
Thanx for ur reply well in our case we have registered a new MX record as what you can see.
We've come to conclusion that Lotus Domino Notes (R6) will be in front now coz it has an option of Smart Host so if it dosent have the user in Lotus it will forward to Postfix.
Thanx any ways
cheers!!!!
