This is a weird problem, and I haven't found the answer yet.  


I am working with a network of 4 stations, with #1 the mail server  
and #4 the UUCP host.  For some reason, UUCP cannot seem to rmail  
incoming messages to people on the network like it could before  
system 3.0 was installed.  Everything ends up in /usr/spool/mqueue  
with the following type of header in the message:

Note that stuff about the connection being reset. I haven't found out  
what any of it means.

Mail _passing through_ the uucp machine continues on its merry way  
unhindered.  Other clues are the abundance of sendmail processes:

tybrin4 [~]-3>ps cuax | grep sendmail
root       116   0.0  1.9 1.55M  384K ?  S     0:00 sendmail

-------------------------------------------------------------------
There used to only one sendmail process going, maybe two at most at  
times.

Other info:  This is an excerpt from a mailq listing:

The mail system works like it did before the 3.0 upgrade in all other  
respects.  I used the SNS application to set up the mail system.  (I  
noticed that now /usr/spool/mail mounted in the / domain as  
tybrin:/usr/spool/mail instead of in the client domains as  
mailhost:/usr/spool/mail.  I have tried both this new way and the old  
way and the result is the same.)


I have been able to successfully telnet to the mail server with the  
smtp argument  (telnet tybrin1 smtp).  This seems to work fine and an  
EXPN on my name works.  


Here is how the what 'mount' says about /usr/spool/mail:

tybrin4 [docs]-31>nidump fstab /
tybrin1:/users /Net nfs rw,net 0 0 

tybrin1:/docs /Net nfs bg,intr,net 0 0 

tybrin1:/LocalApps /Net nfs bg,intr,net 0 0 

tybrin1:/scratch/pub /Net nfs bg,intr,net 0 0 

tybrin2:/LocalApps /Net nfs bg,intr,net,mnttimeo=5,timeo=14 0 0 

tybrin4:/LocalApps /Net nfs bg,intr,net,mnttimeo=5,timeo=14 0 0 

tybrin4:/local /Net nfs bg,intr,net,mnttimeo=5,timeo=14 0 0 

tybrin3:/local /Net nfs bg,intr,net,mnttimeo=5,timeo=14 0 0 

tybrin2:/local /Net nfs bg,intr,net,mnttimeo=5,timeo=14 0 0 

tybrin1:/local /Net nfs bg,intr,net 0 0 

tybrin1:/code /Net nfs bg,intr,net 0 0 

tybrin1:/LocalLibrary /LocalLibrary nfs  
rw,bg,timeo=14,mnttimeo=5,intr,noquota 0 0 

tybrin1:/usr/spool/mail /usr/spool/mail nfs rw,bg,mnttimeo=5,timeo=14  
0 0 

---------------------------------------------------------------------

(If anybody sees anything else bad that I am doing, let me know.)  
Anyway, there's /usr/spool/mail's mount on the last line.

If you've read to here, thanks.  I have scoured everything scourable  
trying to find an answer.  Any clues or hints or outright answers to  
why this problem exists are welcome.

Please send them to ...uunet!sci34hub!tybrin4!holli!me, since, of  
course, uunet!sci34hub!tybrin4!trey ends up being deferred and lost  
in mqueue
