See if the messages in question are from AOL users.
We have a similar issue at various times.
What we have found is that OE and NS choke on messages (joke lists usually)
that have been forwarded through a number of AOL users with many recipients
listed.
Result is large mail header that crosses a threshold and causes a server
timeout on dialup clients (at least on our system. No cable or dsl). Usually
while "retrieving X of Y messages" where X is last good message and X+1 is
the oversize header message.
If they go into web messaging and delete the offending message all is well.
See if this is the cause in your case.
