smail Red Hat 5.0 not seeing local users

Post by Jim Rosenbe » Wed, 13 May 1998 04:00:00

I'm trying to get smail running on a new Red Hat 5.0 Linux installation.  I
downloaded the source rpm from for (the binary dumped
core, alas ...) Getting it to build was a bit of an adventure -- Red Hat 5.0
doesn't seem to have an ndbm library anywhere I can find; I got it compile by
searching libraries -ldb -lresolv.  So far so good.  It seems to run fine 99%
of the time.

** BUT ** ... Roughly once a day a message will bounce.  The message is coming
in via SMTP from another host on my network for a user on the Red Hat box.  
(Well, actually not a "terminal" user but a POP3 client.) I've been able to
capture several of these failing messages, and there appears to be nothing
wrong with them; they are addressed to a user on my network that appears to be
completely legitimate. (Of course I don't have a capture of the SMTP envelope
..)  It seems that just every now and then, smail is asking if a user exists
and is deciding no erroneously.  At this point I have no idea what to look
for.  Is this an smail problem?  A Red Hat library problem?  Real bummer.

Despite repeated attempts, I've never yet succeeded in making the failure
happen.  A number, but not all, of the failures are Pegasus return receipts,
meaning that it simply can't be fuddle-fingered users.  I constantly preach to
use the address book and not type E-mail addresses in the To: box; the users
in this case say they're doing that, and nothing I'm seeing from the capture
messages makes it looks otherwise.

The mail server is upgraded from a Slackware/smail installation that ran
flawlessly for 2 years; I'm going nuts.  If anyone has any suggestions I'm all
