PTR record has broken, need it fixed quickly please, outbound mail is getting rejected :(

Help! My PTR record used to be fine, but somehow just mysteriously changed to "biz", and so now outgoing email is getting rejected by Cloudmark. (Ironically, it's email to a comcast user where I've first noticed it; funny that comcast doesn't know I'm a customer). So I rather urgently need my PTR record for [EDIT: CPNI]. (My other ip#s in the block seem fine, which is strange. How did this happen? I haven't done or tried to do anything dns-related at all so this is a mystery how it happened.)

I run some email lists and do a lot of legit outbound email, so I hope someone notices this post quickly and can fix expeditiously. :)  I see that the normal protocol is to PM someone, but I'm hoping you can just fix it (ASAP) given what I've posted here, since the other ip#s in the block are still tech-soft.com, and being set to "biz" makes no sense whatsoever. You should also be able to see, I presume, that it was previously set to tech-soft.com until the sudden recent inexplicable change. If you need further info, please call me at the phone# on my account.

Please tell Cloudmark it's fine too.  Thx.
