Close. Create John on the exchange server as usual ([EMAIL PROTECTED]), but add a second email address for john@[202.162.2.1]. Leave the primary SMTP address as [EMAIL PROTECTED] > > John send email out > -------------------- > john point the SMTP server to Linux(abc.com ) will do..:) Yes, you could do that, but its easier to leave John sending out through the exchange server in the normal manner. > John Receive email > ------------------- > So John, this public user ([EMAIL PROTECTED]) - When he wants to > receive email, > what is his POP3 server address? > IF point Linux (abc.com) the result will be user not found. > IF point to Exchange 2000 (202.162.2.1), then i think this is > the right > one? I thought John was an internal, not public user? The internal users would probably use the Exchange server client, not POP/SMTP. You could set up the internal users to use POP/SMTP via Exchange if you really want to. The public users on the linux box wouldn't change from their current setup (which could well be POP/SMTP to the linux box). > By the way,can u provide more info in this Linux server, virtual user > table, how to setup? how to configure? ( I think i am > beginner in Linux ) Hmm, you might want to get some help or do some web research for this. The short version is to enable FEATURE(`virtusertable', `hash /etc/mail/virtusertable')dnl in the mc file, run m4 to convert the mc file into sendmail.cf, copy sendmail.cf into the /etc or /etc/mail directory and restart sendmail. Then, edit the /etc/mail/virtusertable file to contain the user redirection lines discussed previously: [EMAIL PROTECTED] john@[202.162.2.1] and finally, compile the virtusertable file with makemap hash virtusertable < virtusertable (do this in the /etc/mail directory). and thats it. Remember to re-run the makemap command above when you update the virtusertable text file. Cheers, Marty List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm
