I suggest using two unix groups, one for web and the other for mail. Then
store the quota in some suitable LDAP attribute (NB the standard schemas
don't have a suitable attribute).
Then write a cron job which calls the following LDAP query:
ldapsearch -x
"(&(modifyTimestamp>=20010531105821Z)(objectClass=posixAccount))" uidNumber
gidNumber quota | grep -v ^# | grep -v ^dn:
and then sets up quota entries from the "quota" attribute. The
modifyTimestamp attribute value should have the time of the last time the
cron job ran.
Eventually I think I'll develop a debian package of scripts for doing this
type of stuff, so if you write such a cron job then make sure you send me a
copy. ;)

I've got user names much longer than 8 characters without any problems.
After 31 characters the names can't be represented in utmp properly (which
can cause some minor hassles for login accounts and will stuff up Portslave
amoung other programs). But there's no problems for other things.
I've done tests with user-names around 60 characters long in LDAP and my
(admittedly basic) tests worked fine.
