OK, that accounts for the inconsistent DNS indications I saw.  That had
nothing to do with spam, by the way, but I have known of companies that
ran into problems when the changed DNS and moved to previously
blacklisted IPs.

By the way, when I said that you were not on any blacklists, that
includes SURBL.  I always check them; they're both important (widely
used) and usually allergic to false positives.  You might consider the
possibility that the problem lies, not with SURBL, but with LinkedIn,
which has a reputation for being a lot less reasonable.

It could be either one.  If you have any email marketing efforts ongoing
(and what company does not?), I'd check to ensure that they aren't
emailing lists that they didn't build manually, and that the email
addresses are all valid and engaged.  But I certainly did not see any
indications of trouble either on my own platform or on any of several
others that I have access to.

Blacklists often don't.  Those of us who do anti-spam have learned to
our cost that revealing information can lead to identification of
spamtraps, and to lawsuits by companies who have unclean hands but also
more money for lawyers than we do. :/  Unfortunately it also hinders our
efforts to improve things, because of course ISPs and companies need to
know where the problems lie to fix them.

As I said earlier, your domain is not currently listed on any of the
SURBL lists that I checked.  My suspicion is that you are running up
against problems at LinkedIn, not with SURBL.

I wish I could suggest what to do next, but I'm stumped.
