This is normal and EXACTLY what happens here. When you set limits to the NUMBER 
of messages (EG I use  a maximum number of Msgs between 100 - 1000 plus a 
maximum time of 1 year,) on a Squish message base, the Squish API ensures those 
limits are retained number is kept. What you really need to be aware of is that 
the actual disk SPACE consumed by the "deleted" messages is not "released" 
until SQPACK (or is equivalent) is run. This also means that once messages HAVE 
expired, the space they occupied is RE-USED for new messages. The net result is 
a slow increase in message base size as the FREE fragments of message base 
become too hold new messages to allow new message to be inserted over old ones, 
so the message base needs to expanded to allow the new ones to be inserted. The 
"problem" is similar to fragmentation of an old FAT drive, the message base 
becomes more and more inefficient over time...;-)

Cheers...........pk.
