resolvel check

hi, is there a way to do resolve checks with qmail?

mails like:

this-domain-does@obviously-not-exist.asdfasfasdfadsfasdf.c0m -->
existing-user@my.mta.tld

should simply not be accepted. i was googeling quite a while but couldn't
find anything.

i am not lazy to read howto's and manuals, so if you can just point me out
a good howto, manual, url i would be very happy :-)

thanks a lot in advance
Lavelle

Take a look at Nagy Balazs's patch
http://qmail.qbiz.de/qmail-1.03-mfcheck.3.patch
-> checks incoming mail's return-path domain (the smtp's "mail from:")
wether it exists or not. Pretty useful!

Best regards,
Thomas.

This is not something qmail does by default. assuming the domain is in
rcpthosts, qmail-smtpd will always accept a recipient then generate a
bounce email later.

However, there are some patches to accomplish your goal. Please google
for the following:

"qmail realrcpto"
"qmail goodrcptto"
"qmail badrcptto"

The first attempts to determine whether or not the recipient would
bounce and rejects at the SMTP level, the second has you keep a database
of good addresses and then rejects the rest, and the last has you keep a
database of bad addresses (a la badmailfrom).

Enjoy,

He wanted to check the envelope sender mailbox name, not the envelope
recipient mailbox names.

I misread the "existing-user" bit. My mistake. JdBP's link would be much
more helpful for the problem you are trying to solve.

So did I, the first time that I read the message. I got partway through
composing a reply along the same lines as yours before I noticed.

In general, one should always consult <URL:http://qmail.faqts.com./> before
posting a "qmail" question to Usenet or a mailing list.
