Do you have the IP addresses that Inmotionhosting.com sends from?  I can look
those up on the spam reporting services and give you a definite answer.

My suspicion is that if comcast is saying it's often a spam source, it'll also
show up in the reporting services, which others are using as well.  And the
only solution at that point is to stop using that hosting service if they have
a spammer-friendly attitude or are understaffed in responding to spam
complaints.

[Moments later]

Taking a quick google search, I think the problem is that they don't choke
outbound port 25 through a central spam-checking service.  So anyone can rent
a host, start spewing spam, and not get shut off until the complaints are
significant.  If that's the case, I don't have much hope for this kind of
service... it's likely to continue to have a "dirty" reputation.

If you want to continue hosting there, get them to divert outbound 25 to an
internal relay to throttle and discard spam.  If they are unwilling to do
that, change hosting, because that would make them spam-hosting friendly,
triggering spam alerts from time to time.
