Beilin is right, in sendmail you can use the "access" file to allow a mail 
server to connect regardless the state of what RBL says, with the syntax;

Connect:paylessoffice.com       OK

make; and restart your sendmail server.

You can ask your customer's IT admin to white list your mail server, that's
something that he has control.

Does anyone on the list have any prior experience with the folks at
sorbs.net? For the past few weeks a customer who uses a blacklist
supplied by them has had our emails blocked. Previous to this the
company had no problem getting our emails. People at said company want
to receive our emails and are frustrated that they can't receive them
(important stuff like invoices and statements), but their IT admin says
he has no control over the list itself. 

I went to sorbs.net, checked our status using one of their utilities,
and the IP of our mail server shows up on their list. I've even sent in
a request to be removed from the list and have received a ticket number.
In their procedures for delisting, they claim that you must "donate" $50
per email they supposedly received in their spam traps, and the
donations are to be made to 2 charities of their choice. I for one think
this is extortion, regardless of whether the intention is to stop
spammers.

Any background or experience you can share would be appreciated. Thanks
in advance...
