Hello, I am having a dispute with the hosting provider of one of the
domains that my client owns (dovetailtech.org). I am trying to send
mail from another domain that my client owns and that I manage
(18884taurox.com) to dovetail, and it bounces. The hosting provider
says it is getting through. I would like someone to tell me whose
head is up their butt: mine or the other hosting provider, preferably
with a good explanation of why.

Some background: I was in the process of migrating all of the domains
to a single server, unfortunately I changed some of the dns records
prematurely, and then a couple of other crises interrupted, so for a
while I knew that I couldn't send from 18884taurox to dovetail, but I
figured that once I got around to correcting the dns records all would
be well. Over time I found it necessary to undo my earlier dns
follies, and it seemed to work for a third domain, findcure.org. But
when I undid the dns for dovetail, I was getting bounces. I saw
something in a newsgroup somewhere that suggested that I needed a
valid PTR record for reverse lookups (which I discovered I was
missing), but that doesn't seem to have helped.

Here is a snip of my maillog. First I send a message to two people at
dovetail that looks to me like it bounces, and then to findcure, which
looks like it goes through.
