Virtual email users in a multi domain server.

Mohan] — Mon, 22 Jan 2001 08:03:13 GMT

I've setup my Linux Redhat 6.2 as a DNS, and sendmail server. My virtual email users wants their reply email to reflect their domain name, instead of the main domain name.
I've tried using the Masquerate_domain command, but it did not work. What went wrong?

Please help.

A good start is the document:

I,ve did follow the steps, but it does not solve the problem. Attached is the sendmail.mc file.

The sendmail was setup only for my company, but recently I've to setup the mail server to accept emails from 2 other companies. I've created the domain, and assign the IP address to it.
I've include the MX record to point to my mail server.
The sendmail.cw file was updated with the domain names: ifood.com.sg ; bizgro.com.sg ; itradessential.com .
I've also updated the /etc/mail/virtusertable to map the email address to the local name.

The email works fine, but it shows the main domain name whenever they send, or reply an email.
Should I use some form of MASQUERADE in the sendmail.mc file? I've inserted the MASQUERADE_DOMAIN_FILE(/etc/mail/masq-domains), but it does not help.

Masquerading will replace all domains specified in the MASQUERADE_DOMAIN_FILE with a single domain, you can't be selective.

You should disable masquerading and make use of userdb on a per-user basis.

See section 33.5 in the O'Reilly book for more information.
