Blocking Delivery Status Notifications?

[Remco Barendse]

Thanks for the tips!

Have been trying to recompile sendmail from source, spent sevarl days
trying to get it to work but couldn't. The newer sendmail SRPM's from
RedHat 7/8 will not build on older RedHat 6 boxes without effectively
upgrading the box to RedHat 8.

Isn't it possible to have MailScanner reset the DSN flag in the envelope
as an option ? (Maybe grep and delete the DSN enabling part)?

It's very annoying that people from outside can see who / when reads their
e-mails especially with e-mails that are quitly forwarded to laptops  or
mobile phones! Think other ppl must have this problem as well?

I have tried to make the modification in the Makefile of the SRPM but this
is not so easy either.
