[cobalt-users] Raq4 Email Aliases - User Unknown

["Cliff Mattox" <cliff@xxxxxxxxxxxxxx>]

Reposting. I accidentally sent the previous one in html. Please forgive me.
I am a newbie on this list.

Gurus,

None of my email aliases accept email on my Raq4. Usernames work great
though.

Example

username bsmith@xxxxxxx
alias bill.smith@xxxxxxx

Send mail to both of them and bsmith mail is delivered but bill.smith is a
unknown user.

Can anyone help me troubleshoot this. I am fairly new on Linux, Sendmail,
and Cobalt

Thanks in advance.

Cliff
