good questions...i didn't include this info in the mail since it was pretty wordy already and the system is a stock freebsd system - no surprises. the sendmail version is 8.6.12. i didn't keep my sendmail.cf from before. the sendmail.cf i'm using is the one that is installed with the stock system with the only change being the addition of "remuda.com" to the Cw line. the timeouts i set are all either 1 hour (for stuff like mail, and quit) and 2 hours for rcpt and data. the defaults are usually about 10 minutes. the gateway is very lightly loaded. also, telnet to port 25 of the problem sites works just fine. one more detail that i should have mentioned before. the sites that i have trouble with don't seem to have anything in common. the microsoft folks are obviously running ms exchange with the smtp gateway on winders nt. i think the nintendo site is linux and it's running smap. i don't have a clue what msn is using but gonna guess that winders nt is involved. i'd like to reiterate that the problems are 100% reproducable with the sites i'm having trouble with while mail to everyone else works just fine. i did some testing with another freebsd box (stock install again) and the sites that are causing problems for my box don't affect it (i built both, both are on different net connections). i stole it's sendmail.cf but it didn't help. i'm gonna rebuild and see if that helps. i'll post results to the lists. scotto >---------- >From: Doug Wellington[SMTP:doug@sun1paztcn.wr.usgs.gov] >Sent: Saturday, May 18, 1996 12:26 AM >To: Scott Overholser >Cc: Scott Overholser (Volt Computer) (Exchange); >freebsd-questions@FreeBSD.ORG; freebsd-hackers@FreeBSD.ORG; >freebsd-isp@FreeBSD.ORG; freebsd-bugs@FreeBSD.ORG; >doug@sun1paztcn.wr.usgs.gov >Subject: Re: sendmail read errors/timeouts etc. > >Previously: >>i recently replaced my email gateway with a freebsd 2.1.0 box. prior to >>that it was a linux box (different hardware) running sendmail 8.6.11 and >>100% trouble free. now though, i am seeing sendmail errors when sending to >>a few select sites. in addition, i see them when i receive from the same >>sites. > >Well, I'm gonna start with a couple dumb questions...
