I'd normally attribute this problem to DNS, but I can't track down what DNS problem is occuring. Note the lag between the first event and the next. Any suggestions?
Sendmail attempts to do a "getpeername()" and an identd lookup of the sending process for logging purposes. You can turn this off. For a persistant connection, the second thing that gets sent down it avoids this check.
Do you know what the switch is for turning that off?
It depends on the version of sendmail. If it's not 8.12.5, you will need a local hack; for that, you should look for where the variable "RealHostName" is set in the C sources in sendmail/sendmail/daemon.c.
If it's newer, then there should be an option for your m4 file in sendmail/cf/README (NOT in the book!).
You might also want to play with confTO_IDENT (the 5 second ident timer) and confTO_RESOLVER_RETRY (the resolver timeout).
If you need the local hack, it's pretty rivial, I can walk you through it.
Alternately, you could get the remote side to answer the phone. 8-).
