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-). -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
