SENDMAIL 8.7/8.7: Runs REALLY SLOW - Why?

SENDMAIL 8.7/8.7: Runs REALLY SLOW - Why?

Post by Peter Beckm » Fri, 28 Jun 1996 04:00:00



I've got Sendmail 8.7 installed on this here machine, and for some reason,
it takes a LONG time (30+ seconds) for the sendmail daemon to start up.
It's like it's looking for something, can't find it, times out, and then
runs itself.  

Has anyone else had this problem?  I'm invoking it like this:
/usr/lib/sendmail -bd -q30h

Why for art this happening?

Peter-
        When I hear about delays like this I always, always suspect
        DNS timeouts.  Check to see how long a host lookup takes for
        hostnames mentioned in the .cf file (in particular, localhost
        or the hostname of the system on which sendmail 8.7 is running).

        You might use a tool like dig or nslookup.  I like dig as it
        reports time spent.  If it is a delay then check out the order
        of hostnames in /etc/resolv.conf.  Perhaps you are aiming at
        a non-functional DNS server.

        And I suggest in the future when you ask questions like this
        you also include (at the very least):
                system type (sparc, hppa)
                OS and version
                patches installed (if they seem relevant)
                When the problem started (yesterday or 2 years ago?)

        Of course that last paragraph is aimed at every seeker in
        comp.unix.admin rather than just you!

1. Aix 4.2.1 running sendmail AIX4.2/UCB 8.7 How do I stop relaying?

Hello All,
   How do I go about configuring AIX's /etc/sendail.cf to not allow
all to relay?  In 'regular' sendmail you can specify:

FR-o /etc/mail/relay-domains
which I can modify a flat file specifying domains to allow relaying

Kaccess hash -o /etc/mail/access
or modify the access file using IP addresses &/or wildcards.

Is there something simular for AIX's sendmail?

Thanks for your help:)

Stephan
