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. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

For incoming connections you are looking at the ratecontrol and conncontrol features, see /usr/share/sendmail/cf/README. For outgoing, I don't know. Why would you want to be so nice to the Yahoo.com server ;) They should rate-limit their server if they have a problem (and I bet they do this). There is a SINGLE_THREAD_DELIVERY option, but that's probably not what you want. cheers, Ruben ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
