[TriLUG] Trouble sending mail to RR addresses

Pete,

If you, like me, have your personal domain hung off of a cable modem,
then you are correct in that #3 is your "problem".  I just have all
clients configured to use smtp-server.nc.rr.com as my outbound server.
All is well.

|
| Feb 17 18:07:52 albert postfix/smtp[24719]: D17753B1B4:
| to=<someone at nc.rr.com>, relay=ncmx03.mgw.rr.com[24.25.4.97], delay=1,
| status=bounced (host ncmx03.mgw.rr.com[24.25.4.97] said: 550 5.7.1 Mail
| Refused - 24.25.31 - See http://security.rr.com/mail_blocks.htm#security
| - 20031206)
|
| This is something relatively new since I distinctly remember not having
| this problem the last time it was discussed on the list. Unfortunately I
| cleaned out my Sent Items folder the other day can cannot tell when last
| I successfully set to an nc.rr.com email.
|
| According the the page supplied in the error message, this error
| indicates one of the following:
|
| 1. The sending machine or network has a security problem associated with
| it, which resulted in the sending of unsolicited bulk mail to our
| subscribers or role accounts.
| 2. The sending machine or network is actively attacking our mail servers
| (mailbomb, DoS attack, etc).
| 3. The sending machine or network is located within a dynamically
| assigned IP address pool, and the ISP owning that pool has a stated "no
| server" policy.
| 4. The sending machine or network is not in compliance with Road
| Runner's posted Inbound Sending Policies
|
| I assume I could fix 1,2 and 4. However if 3 is the case I would be
| stuck. Correct?
|
| I am pretty sure my postfix server is configured not to relay anything.
| It should only accept mail destined for my domain or mail from my
| private network. Here is the content of main.cf:
|
| myorigin = $mydomain
| mydestination = $myhostname, localhost.$mydomain, $mydomain,
| mail.$mydomain, www.$mydomain, ftp.$mydomain
| mynetworks = 192.168.0.0/24.0, 127.0.0.0/8
|
| I suspect that I am being bounced because I am using a Dynamic IP
| address. However, I am sure that there are others on this list running
| there own mail server on RoadRunner with dynamic IP's. Is anyone else
| having this problem?
