As one whos been doing that for about 20 yrs, including for ISP's, its 
only a hassle if you are doing it wrong.

thats what portal scripts/hooks are for, and if they leave, tough, it 
all goes when the close date hits, its how its been done everywhere I've 
worked and been with as end user.

Welcome to the internet, but if you do it right, your anti spam software 
workload can be reduced by a huge margin, SPF, multi DBSBLs, DNS+rDNS 
enforcement (that kills greater than 70% of the crap- and no its not my 
problem if some jackass doesnt know how to make sure their mail server 
has good DNS), I also nuke things that sound like dynamic addresses, and 
a few more tricks.
