Yes, there is a limit for the incoming connections.  See the description
of "confCONNECTION_RATE_THROTTLE" and "confCONNECTION_RATE_WINDOW_SIZE"
in "/usr/share/sendmail/cf/README".

For outgoing connections Sendmail only supports throttling based on the
load average of the system, at least AFAIK.  So you will probably have to
use some sort of connection rate-limiting in your firewall if you want to
limit the number of outgoing connections.
