Like I posed in your other post

Are your emails sitting in the mail queue?
run
#mailq
if you have allot of messages in your mailq
then run
#sendmail -q -v
this will clear out your messages.

in my /etc/mail/sendmail.cf
I have this set for 5 minutes.

# minimum time in queue before retry
O MinQueueAge=15m

MinQueueAge=age
[no short name] Don't process any queued jobs that have been in the queue less than the indicated time interval. This is intended to allow you to get responsiveness by processing the queue fairly frequently without thrashing your system by trying jobs too often. The default units are minutes

and about posting messages in the wrong place. They are pretty good about catching them and putting them in the right section.

Like posted in other thread:

Hi,

Has the load of your system been very high between this time ?
Sendmail stops working if the load is above some point.
This is somewhere in the sendmail.cf file.

Richard, we use sendmail to notify us when we system shuts down and rebooted (scheduled every Sun night) thru email paging (myairmail.com). Everything was working fine until we had to move to (myairmail.com) from (airtouch.com). That's when things started to slow and page out of sequence. Hence the mail.log. We don't send any local emails on unix side unless it's a sysadmin nature, therefore not a lot gets queued. Sendmail.cf file is commented on MinQueAge.

Clemens, this email page is supposed to transmit after a system reboot. Not a lot happening during startup.

Richard, we have to send to myairmail.com now. airtouch.com was bought by myairmail.com.

nslookup returns
myairmail.com
168.201.2.217

Mail works thru myairmail.com, it just sometimes takes it a while to process. As I said before, only sysadmin stuff gets mailed to our text pagers by email.

When you do

echo test | sendmail -v whoever@myairmail.com

does it say something like message queued for future delivery?

Is mail delayed when you try to send from other email services besides the one on your unix server?

Curtis Whitworth — Tue, 16 Apr 2002 17:37:28 GMT

Richard, yes it does.

Name server timeout
Transient parse error -- message queued for future delivery
queued

Do you have your dns servers in /etc/resolv.conf ?
and in /etc/nsswitch.conf do you have dns for hosts?

Richard

someone_4 — Tue, 16 Apr 2002 17:44:17 GMT

You also said that

nslookup returns
myairmail.com
168.201.2.217

can you ping myairmail.com
or can you ping 168.201.2.217

Attached are copies of the files.

Re: Sendmail delay

someone_4 — Tue, 16 Apr 2002 17:49:57 GMT

Try commenting your line out:

#hosts: files [NOTFOUND=continue UNAVAIL=continue] dns [NOTFOUND=return UNAVAIL=continue TRYAGAIN=return

and make it look like this:

hosts: files [NOTFOUND=continue TRYAGAIN=continue] dns

Curtis Whitworth — Tue, 16 Apr 2002 18:52:25 GMT

Richard, thanks for all your input. Looks like we are trying to send to myairmail.com from UNIX instead of our MS-Exchange system. I'll change the "smart relay" to point to Exchange and run test.

Re: Sendmail delay

someone_4 — Tue, 16 Apr 2002 18:58:55 GMT

Hey Curtis
Let us know what happends. And dont foget to restart sendmail after your turn on your smart relay.
/sbin/init.d/sendmail stop
/sbin/init.d/sendmail start
And make sure you can resolve to your exchange server. The DS takes ip or hostname too.

Hey Curtuis
Did everything work out for you?

Re: Sendmail delay

Curtis Whitworth — Fri, 19 Apr 2002 15:43:57 GMT

Had to call HP Support to finally fix problem... Changed my resolv.conf to search domain. Changed nsswitch.conf to search files then dns. And finally changed sendmail.cf DS macro to the fully qualified domain name of the relay server. I think this is were all problems originated. It had only the short name. Now everything is working great! Thanks for your help.
