Hi,

I'm using postfix as my MTA on one of my mail servers. We are using a
wholesaler to provide us
with dialup phone numbers nationwide. I need to enable relaying on their
blocks of dialup IP
addresses.

As an example, one of the dialup IP blocks is 64.24.0.0/16 So I put
64.24.0.0/16 in relay_domains in
main.cf and I also put 64.24.0.0/16 in access (with the parameter OK) and
created access.db using postmap.
When one of my customers dials into that location, she gers this error
message:

Nov 30 15:35:42 localhost postfix/smtpd[22385]: reject: RCPT from
02-186.751.popsite.net[64.24.209.186]: 554 <vinny1rcn.com>: Relay access
denied; from=<mssskgcampbellcountry.com> to=<vinny1rcn.com>

So my relaying is not working. I thought maybe postfix does not understand
the CIDR notation (like SXendmail does not) so I changed 64.24.0.0/16 to
just 64.24.0.0 in both main.cf (relay_domains) and in access. I redid
access.db then restarted postfix. She is still getting a relay access
denied.

What do I need to do to make this work?

Thanks,

Lisa Casey
