I set up sendmail 5.65 (no IDA) so I'd get file locking, and get rid of the clutter in my spool dirs...everything seems to work fine (for a couple of months, at least). I mailed something to someone here at lehigh the other day, and got a message back saying that my domain was'nt in the address when a reply was attempted. For example: I'm at porphano@calvin.sfc.lehigh.edu But the message was delevered identifying porphano@calvin as the sender. I was mailing out of my subnet, so the entire address should've been generated (it usually is when things are 'normal', if there is such a thing). The funny part is that if I simply rebuild the sendmail.fc file, everything's back to normal. This happened once before too, and I applied the same remedy...no problem. Do I just sit around, and wait until it breaks again? Another notable item is that when I rebuild the sendmail.fc file, it's a different size than before (I did'nt touch the sendmail.cf file). So it seems to be that sendmail is fooling around with the fc file. Any suggestions would be most appreciated....I though I could set this up and leave it alone. Just like everything else on this system :^) Thanks in advance.... Paul

I was mailing out of my subnet, so the entire address Make sure you don't have a broken resolver library. 'sendmail' attempts to find your own name by taking the output of hostname(), then qualifying it with your nameserver. Some systems have broken resolver libraries which search /etc/hosts before they search the nameserver database. This can lead to unqualified names. >The funny part is that if I simply rebuild the sendmail.fc file, >everything's back to normal. This happened once before too, and I >applied the same remedy...no problem. This might not be related. All addresses are passed through the nameserver lookup at some time. Thus the freeze file information may not be the final word. You can determine what sendmail thinks is your hostname by a telnet to your smtp port. The Hello message gives the hostname frozen in sendmail.fc >Do I just sit around, and wait until it breaks again? Another notable >item is that when I rebuild the sendmail.fc file, it's a different >size than before (I did'nt touch the sendmail.cf file). So it seems to Lots of things can effect the size of 'sendmail.fc'. If you are using FU|uuname|sort|uniq then adding or removing a uucp node will change the size of 'sendmail.fc'. What is in your environment when you build the freeze file can also effect the size. >be that sendmail is fooling around with the fc file. No. Sendmail only reads this file, except when -bz is used. -- =*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= Neil W.
