For sendmail I had much rather thought about option 1) and absolutely not about option 2) as if you have ever known what S5 was and could no longer read your $ sign and 4 on the keyb you know that sendmail people are not lazy or clueless! Back to the OI problem: > 8.12.7/8.12.7 2002/12/29 yes, that's not from stone age:( It's quite said, that systems not being able to poperly resolve hostnames are doing emails these days. Anyway, yeah, it's good that it's only config files; nethertheless I don't like it as you probably do not either. Have you ever thought about having those files changed just for FreeBSD? Or had there been porblems on FreeBSD systems with localhost as well? Has it been a special time with localhost and IPv6 that casued problems as 2002 has been rather late in terms of sendmail and resolver etc. What had started to cause those problems? /bz -- Bjoern A.
