I want to use uk.dev1.com as well as hydlmuk.com. In fact I will be creating one more domain called "uk.crp1.com" and would send mail from all of these domains at the same time. -------------------------------- Here is what I did to change the "From id" for outgoing mail. - created a file named genericstable to map a local user to a <user>@domain: Ex: <localuserid> <userid>@uk.dev1.com In your case, I guess <localuserid> and <userid> would be the same. All e-mail sent by <localuserid> will have uk.dev1.com as its domain name. - in the /etc/mail directory, ran the following command: Makemap -r hash genericstable.db < genericstable - added the output of the "hostname -f" command into a file called "generics-domains" - added these two lines to sendmail.mc FEATURE(genericstable, `hash -o /etc/mail/genericstable') GENERICS_DOMAIN_FILE(`/etc/mail/genericsdomain') - recompiled sendmail.mc: m4 <sendmail.mc > sendmail.cf This worked for my limited use of it. I'm definitely not an expert with sendmail but I hope this can help. You may need to play around with it. The GENERICS_DOMAIN_FILE may need all your fully-qualified domain names. I only have one domain name but I use the generics table to map different users to different e-mail accounts on different internet domains. Somebody else on this list could probably tell you if this would work the same when one machine has several domains.
