Cannot send mail from another account than 'root'

I need help.

A reply to an existing ticket only reaches the recepient if I am logged in
to RT web interface as ‘root’. If I login as another user I get the normal
confirmation from RT but the mail isn’t sent.
I see no error message in RT’s, apache’s, sendmail’s or Solaris’ log file.
Via RT web interface I granted all users the right to reply to a ticket. I
also tried granting superuser privileges - without success.

Is somebody able to help?

Thanks in advance,

Roland.

Do the sendmail logs indicate a message is being sent? Are you sure
it’s not something external?
