It just gets stranger and stranger. Postfix did and does have 
mailbox_size_limit=0 so there is no maximum mailbox size. It did appear 
last night when I was checking that it might have something to do with 
the size of the mail spool because squirrelmail would work on accounts 
with no or small amounts of email but not on accounts with large email 
files. However, this morning I put that theory to the test by using a 
test account and sending messages with attachments. Right now the 
account has a spool file of 40 MB, more than two who are having 
problems, and squirrelmail works fine. Now that 40 MB is from 6 email 
and not 2000 emails so I don't know if that's an issue or not.

One other thing, when moving from by dead RHEL3 system (the drive died 
but I was able to recover the unread mail (hang the dead drive outside 
the case and turn a big fan on high to keep it cool) after the ubuntu 
system was running. I merged the two sets of spool files with mmv 
(http://debaday.livejournal.com/33924.html) to append the new mail spool 
to the old mail spool. I don't see this as a problem but I did do it for 
those who had unread mail which was most. Most of my users are pop and 
so don't have large spool files as a rule.
