Re: MX accept policy: problem
Matti and all,
[*] No, that is WRONG syntax:
Sorry, that syntax error was just a mail typo, in my smtp-policy.src i got
no such syntax error, <duh>.
My figure is quite simple, i will explain very simply what i want, and then
i am sure you will provide a quick and clarifying response.
I have some 100 big customers which use my ZMailer server as MX backup or
ETRN MX for their domains, this makes my smtp-policy.mx file huge and kind
of complicated to maintain manually. I thought that since all those 150
customers were grouped in only 5 different networks i could list those
'friendly' networks in my smtp-policy.src with some special rights
so they could use my zmailer server as MX, and then get rid of (eliminate)
my smtp-policy.mx file completely for easier administration.
I have been testing something like this in my smtp-policy.src:
# this is for protection
. relaycustomer - acceptifmx - senderokwithdns +
[0.0.0.0]/0 relaycustomer - acceptifmx - senderokwithdns +
[*] Yes, this is what for example nic.funet.fi runs with.
[*] This is all that an inbound MX processing is accepted.
[*] (recipient MX processing means testing for *domains*,
[*] e.g. the last resort key will be '.')
# this is one of my 'friendly' networks
[188.8.131.52]/24 rejectnet - relaycustnet - relaytarget + acceptifmx +
Mail relaying from those networks is just fine, that is *not* the issue, ok.
The suffix solution is not what i need, since all those customers have
different domain suffixes and including them in my file would be the same
as maintaining smtp-policy.mx (the amount of entries would be the same).
With that configuration when i try to send email to someone in that friendly
network - from an untrusted network - i get this in my smtpserver log:

What can i do to get MX reception allowed without any smtp-policy.mx file?
Thanks a lot,
