No, that is normal. You turn off services (IMAP, for example) you don't need and leave on ones you do (ftp, for example). You block ports that aren't being used, say, for the unused services. You meter the network (like mine does--I can't possibly take more than a certain fraction of total bandwidth) or you look for excessively large percentages of use (assuming your other uses are being degraded) and take action (meter that use, find a separate network for it, have large use take place during off hours, etc.).

On my servers we turn off services we don't need. That way, if an exploit comes out for SAMBA, and we aren't running it, we aren't at risk. If someone wants something turned on, they put in a request. If I want a blocked website unblocked, I put in a request.

It is easier to monitor a few ports than tens of thousands of ports. It is easier to patch servers for (currently) unused services quarterly rather than when a patch comes out.

Knocking an organization for managing their resources really isn't fair. I've seen mismanagement (make the admin's life easier) and I've seen lots of good management (balance safety and effective uses of the company's resources against the needs of the users). This sounds to me like it could be decent enough management, and I urge the OP to put in a request to allow IMAP--even if he is denied now, I've had my denied requests later granted because others also requested the same thing. Sometimes ports are simply blocked by default and single request is enough to open it up.
