Changing maxsmtp to 5 probably do not change anything because on a local 
smtp server performences are usually very hi. You should change nrcpt to 
a very low value nrcpt = 3.

You can do it on the nrcpt_by_domain file so you will not make sympa too 
slow for non local users.

Another solution is to change the verp_rate list parameter : use 100% 
will be the same as nrcpt=1 for this list.
