[cobalt-users] webmail shows hostname

[SeanBru@xxxxxxx]

Whenever I send mail through webmail (tried open webmail too) it always
shows from: john@xxxxxxxxxxxx instead of john@xxxxxxxxx  I tried changing
the Masquarade option in sendmail.cf file, but I don't know what to change
it to.  I tried forcing senders domain, still didn't work.  Any ideas how to
fix this?  If I send from Outlook it works fine, only happens through the
gui mail sending.

Thanks in advance

Sean
