Hello!
About the postmaster missing for so many domains.
Could this not be considered to also be some fault of the default sendmail
configuration that sends double-bounces to postmaster?
(Dont know how other mta handles this.)

Why?
When a beginner first get that mailbox flooded they might null it in a
hurry. And forget it. Instead of reading through more documentation.

They could be encouraged to configure in sendmail.mc or hostname.mc:
define(`confDOUBLE_BOUNCE_ADDRESS', `exampleaddress')dnl
or:
define(`confDOUBLE_BOUNCE_ADDRESS', `postmaster+notify')dnl
or possible:
define(`confDOUBLE_BOUNCE_ADDRESS', `')dnl
To send it to an alternative address, submailbox or just drop it.

Or for those who dont use m4, something like this in sendmail.cf:
O DoubleBounceAddress=postmaster+notify

Or alternatively these mails can be filtered based on subject by sieve or
procmail or something.

Or maybe sendmail could be encouraged to change their defaults to?



Just thought it would be nice to add some suggestions for these people to
this thread.
