comment If a Windows shop moves “everything” to the cloud, does it still need Active Directory?
If it's purely about licencing cost then OpenLDAP would satisfy your needs but the cost of maintenance / time would probably outstrip the cost of licencing.

comment Removing an IP address from the Spamhaus blacklist
I can't think that Comcast would have knowingly been ok with you sending mail from a dynamic ip. That would suggests that while you thought you were sending mail via comcast that you may not be. spamhaus.org/faq/section/Spamhaus%20PBL#165 has the info, I'd suggest a new SO question giving details of what mail server software you use and ask how to check if it's forwarding outbound mail to comcast's smarthost.

comment Removing an IP address from the Spamhaus blacklist
@JackHumphries - Your presence on the PBL is not because you or anyone else did something bad. You basically have 2 options 1) get a fixed IP and then ask your ISP to remove that from the PBL if they haven't by default. 2) reconfigure your server to forward outbound mail via your ISP. the latter is generally the better option unless you have a good reason not to do so.
