Load Balanced ISPs (FatPipe)- Routing? DNS?


Recommended Posts

I implemented a new Hardware device that allows me to LoadBalance my traffic between 2 (or more) ISPs. Everything seems to be working fine, except that I just recieved this message:


--- The message cannot be delivered to the following address. ---

7815096xxx[at]airmessage.net Permanent error involving remote host.

550 5.7.1 Mail from refused by blackhole site bl.spamcop.net


The IP: wasn't coming back with an entry for a reverse query as I hadn't entered an in-addr.arpa entry. I added it and now get the following from SPAMCOP:


Query bl.spamcop.net - is ns1.sentient.com

(Help) (Trace IP) (Senderbase lookup) listed in bl.spamcop.net (

Since SpamCop started counting, this system has been reported less than 10 times by less than 10 users. It has been sending mail consistently for at least 10.8 days. It has been listed for 42 hours.

In the past week, this system has:

Been detected sending mail to spam traps

Been witnessed sending mail about 20 times


Is everything fixed or am I still screwing this up???
