The weights are not important except they should not be the the same.
Hope this helps

Last days we can see a lot of SMTP_DELIV_FAILED in our logfiles
Looks like there are out many mailservers using a spamfilter solution that blocks all incoming smtp traffic if the sender domain cannot be resolved.
So we've found out that one of our domains has a missing dns entry. Ok resolved.
But there is also another problem: We set up all our virtual mail hosts in the form mail.clientdomain.com and
the alias clientdomain.com
So all webmail users have a default sender address of
[EMAIL PROTECTED]
Now all messages send from webmail with the default sender address are blocked from this receiving mailservers.
Solution: A.) Manualy remove the "mail." for every mailbox user B.) Add an A- or CNAM-Record "mail" to any DNS-zone of all clientdomains
Any suggestions?
So it's now legit to block any mail having an invalid sender domain or is this the "idiots way to filter spam" ?
