I run sendmail-8.13.8 at home to host my domain. Some domains will not
accept mail from me because my address is from a dynamic address pool so
I solved that problem by placing all of those domains in my mailertable
and now route those messages through my ISP(RCN). Recently I have
noticed that some of the mail is hanging for a while with 400 series
messages saying 'Too many connections'. I checked with RCN and after
many wasted hours on hold I found out that I need to limit the maximum
number of connections to their SMTP server to 4. Four shall be the
counting. Five is too many and six is right out!
Can someone please tell me what the incantation is to limit the number of
simultaneous connections to a particular server? I'm not looking to
limit incoming conncetions. I'm not looking to limit the rate of
incoming or outgoing connections. I just want to set the max nr of
connections from me to RCN to no more than four.
Looking at the holy README file of Antioch in the sendmail-cf package,
it appears that setting confHOST_STATUS_DIRECTORY and
confSINGLE_THREAD_DELIVERY will have the result of limiting outbound
connections to any one host to 1. Whilst this is not 4, it's likely to
at least get your mail delivered eventually.
