Okay, here below are what I believe to be pretty much everything
about my network. Anyway, all the stuff that folks asked for.
I have also emailed AT&T to ask them about MTU values. And I have
placed queries on news groups which seem to apply.
Recall that this is about being able to send, via SMTP, short emails of
less than 2K but not being able to send emails of longer than 2K. I will
port this over to floppy and send it via Win98 since it is sure to be
more than 2K chars. At present, I am trying to do by SENDMAIL instead
of KDE's SMTP. Even worse luck with sendmail in that NO emails seem
to get out at all.
I have two systems. When first I noticed this problem, they both
did the same thing with respect to long emails. The two machines
are:
1. A tower unit with an Intel D815EEA2 motherboard
and USRobotics external modem.
2. An IBM ThinkPad 380Z and Linksys 56K modem.
Both are running NetBSD 1.5.1 and KDE2. The laptop had formerly
had NetBSD 1.5 and KDE 1.1.2. I recall from memory that email on
KDE 1.1.2 had given me similar problems with complaints of
<body> and refusing to ever email again. It was a mystery at
the time. I did not then know that deleting the long message from
the que would solve the problem.
I had originally noticed the problem using the KMail SMTP option.
On several recommendations, I have tried to switch to sendmail.
But no emails go out. I have not been successful to get SENDMAIL
to connect to the AT&T gateway. It will time out on each of half
a dozen gateways in succession.
Anything else anybody wants to know, I will go in search of it.
Thanks,
Gan Starling

...Below file originally did not exist, as I was running straight out to
USRobotics modem at tty00. I figured it was for clients sharing a
gateway (some other machine on the LAN?). But, just in case, I
created this anyway. It didn't seem to make a difference. I am
thinking maybe I should remove it now?...

...And Jeremy C. Reed suggested that I try this...
gus# jot -s '' 1000 | mail -s "2894 characters" oinkfreebiker@att.net
gus# (echo "Subject: 2001 characters" ; echo ; jot -s '' -b 'x' +2000 )
| \
/usr/sbin/sendmail oinkfreebiker@att.net
gus#
gus# fetchmail
fetchmail: No mail for oinkfreebiker at postoffice.worldnet.att.net
gus#
...And Thomas Michael Wanka asked me to try this...
gus# telnet gateway4.att.net:25
gateway4.att.net:25: No address associated with hostname
gus#
...which looks like a problem! So, just as a check, I do...
gus# ping netbsd.org
PING netbsd.org (204.152.186.171): 56 data bytes
64 bytes from 204.152.186.171: icmp_seq=0 ttl=243 time=192.949 ms
64 bytes from 204.152.186.171: icmp_seq=1 ttl=243 time=186.379 ms
^Z

gus#
...and then for tripple check I do...
gus# ping gateway4.att.net
PING gateway4.att.net (204.127.134.23): 56 data bytes
64 bytes from 204.127.134.23: icmp_seq=0 ttl=52 time=158.786 ms

gus#
...and now I am very stumped! I know that for KMail's SMTP I had to put
in this address...
mailhost.worldnet.att.net on port 25
...which makes me wonder what is the deal with gateway4.att.net. I know
that that is the address I put in for SMART_HOST. Anyway, here are my
config inputs for sendmail...
