Hi Bob,


You're correct.


2 days ago I changed the MX records from "mail" to "xen5" testing
another mail server running as guest on this Xen box.  That server runs
Unix mailbox.  It can send/receive mails w/o problem with recepient
address to user@satimis.com.  But I need adding "satimis.com" to
mydestination.


About 1/2 hours ago I finished setup this mail server running virtual
domain, also as guest on this Xen box.  I changed MX to "xen01"
matching its hostname.  I'll change MX back to "mail" to see what will
happen.


Thanks
