110.000 subscribers for one list is not a problem for Sympa. We have try to
load 200.000 subscribers in one list without troubles. The question of the
limits of Sympa is frequently asked. here are some guide :

-large list MUST use the RDBMS option of Sympa. MySQL (using the big tables 
option)
 is a really nice RDBMS solution. 
-the limits are not comming from Sympa itself. They are comming from the 
network
 bandwith and the computer and OS limits.
-there is a big difference between a large number of discussion list and a 
large
 list for a new paper. In the first case the distribution processus must be 
very
 fast. Then postfix is probably the best SMTP engine.
-the Web interface will provide nice responce delay if using Fastcgi.

We currently have 125.000 subscribers into 200 mailling list and 6 millions
of messages per mounth on a linux BI-PIII  500 with 512 Mb RAM. Sympa
wwsympa, sendmail (I'am lazy to change to postfix), apache, bounce management
and MySQL run this unique server. It's possible to split it on diffrent 
servers,
in particular you can run MySQL in a dedicated server and use round robin for
several mailhost distributor. 

We are interested in feed back about very big mailing list servers using 
Sympa.
