need opinions re: contact methods for a noc@ alias

Hi there Over the years I've seen a few very odd methods for dealing with a noc@ email address. I've always had the mindset that: 1) individual users are subscribed to a list/alias for noc@ 2) it's _never_ a single/shared "account" 3) it _always_ accepts plaintext email, at the least, for reporting problems. recently I've been seing more of the "single account" that some poor sod on shift uses, and now I've seen it all - an isp who won't accept plaintext email to their noc@ list, but instead want the person sending the report to go to a webform and fill it in. I was wondering what others' thoughts on these and other methods of dealing with noc@ were. Regards --Rob
