Hi,
I use mailx to send short notifications to a bunch of users ( in Lotus Notes ). The undeliverable emails are going to the Notes' Dead Letter basket and creating a problem. I am told by the Notes Admin that I need to specify a 'Return address' so that the bounced emails can go there. I can not find any flags/information as to how to tell MAILX to use a different email address as the "return/dead" address.

Is there such a thing ?
OR is this a Lotus Notes problem in that it is not sending them all back to the originating UNIX email account ?
