I am have a problem sending a uuencoded file from unix.
if I send a regular message 
mailx -s "test" dbrowett_at_city.coquitlam.bc.ca
test
ctrl-d
I get the following message in syslog 
Apr 19 10:43:28 atlantis sendmail[7430]:
KAA0000010024:to=dbrowett_at_city.coquitlam.bc.ca, ctladdr=dbrowett (266/106),
delay=00:00:00, xdelay=00:00:00,
mailer=smtpr, relay=mx.city.coquitlam.bc.ca. [142.219.33.13], stat=Sent (OK)
But if I send a uuencoded file  
mailx -s "test" dbrowett_at_city.coquitlam.bc.ca < uuencoded.file
I get the following message :
Apr 19 10:43:46 atlantis sendmail[10012]: KAA0000010012:
from=dbrowett,size=100028, class=0, pri=130028, nrcpts=1,
msgid=<200204191743.KAA0000010012_at_atlantis.private.coquitlam.bc.ca>,
relay=root_at_localhost
As you can see, the relay is localhost, and what is really strange is
"from=dbrowett"
where it should be dbrowett_at_city......  When I send the uuencoded file, It
truncates the city.coquitlam.bc.ca
I realize this is something in the sendmail.cf file, and I am currently
doing a RTFM, but there is a lot
of pages to read :(
Also, we have had an issue with our domain name expiring (it is now
resolved),  so hopefully you will be able to reply to this email.
Thanks
