Question
I am getting a "bogus MX Records" msg back when I email a user in Exchange
When I email a user I get the following message back from my mail server
"You do not have permission to send to this recipient. For assistance, contact your system administrator.
#5.7.1 smtp;554 5.7.1 Service unavailable; Sender address blocked using bogusmx.rfc-ignorant.org; Domain has demonstrably bogus MX records>"
The user can email me, when I "reply" I get the same error. I could email them a few months ago.
From googling it it may be a problem with their ISP not allowing reverse lookups. Is there anything I can do on my end to resolve it?
Appreciate any assistance.

Your domain has two mail servers listed :-
creganna.com. 86400 IN MX 20 mxbackup4.webhostingirelan
creganna.com. 86400 IN MX 15 newmail.creganna.com.
The first one is fine but mxbackup4.webhostingirelan
mxbackup4.webhostingirelan
According to the RFC standard the MX entry should point to a host which has an A (IP address) record and it is not permitted to post to a record which is a CNAME. This is why you got put on the RBL with rfc-ignorant.
You need to change
mxbackup4.webhostingirelan
to
mxbackup4.webhostingirelan
Then 24 hours after the change has been made (to allow time for the change to propegate) go to http://www.rfc-ignorant.or
I am guessing you are a customer of webhostingireland?
In that case you cant change the record yourself so I would contact their customer support and say to them as a web hosting company they should know what they are doing andnot make such a mistake.
In the meantime you can change :-
creganna.com. 86400 IN MX 20 mxbackup4.webhostingirelan
to
creganna.com. 86400 IN MX 20 mx1.webhostingireland.ie.
This will stop the error and effectivly point to the same machine as the backup.

That looks like a RBL lookup. What is the domain you are sending your email from and what is the servers IP address. If you dont want to post it here there is a 'test' email address listed in my profile which you can send it to. Lust post here when it has been sent.
