You can't define reception mode (digest | nomail | summary) on included
subscribers. We plan to do it on next release via the
"default_user_options"
param.

Sorry, I don't understand what the problem is. 
When you define a "digest" parameter for a list, users may then set
their
reception mode to "digest", unless they are users are included from an
external data source (which seems to be your situation). 
If the list has a "digest" mode, every message is kept in
spool/digest/<listnamse>
file and then sent, as a digest, when time has come.

What is your MTA ? Postfix is supposed to be quite good.
Did you tune the maxsmtp, avg and nrcpt params in sympa.conf.
