[9fans] Odd issue with mail...

[Marina Brown]

Hi All:

I'm trying to get mail set up on plan9 and i am running into some odd 
problems.

I can telnet net!my-gateway-server!smtp and get the smtp prompt. in 
/lib/ndb/local
i have smtp=my-gateway-server, but when i try to send mail i find error 
messages
in /mail/queue saying 'smtp: dns: dns failure (net!$smtp).

The name of my outgoing server is a CNAME if that, perhaps is an issue.

this is what I have in my /lib/ndb/local:

ipnet=localnet ip=192.168.0.0 ipmask=255.255.255.0
	smtp=smtp.gmail.com

and you need to copy /mail/lib/rewrite.gateway to /mail/lib/rewrite

All done. Still i can telnet to the gateway, port 25 but get a dns error 
sending mail.

The exact error is:

smtp glenda net!smtp marina@surferz.net

i copied the rewrite.gatway to rewrite
and i have smtp=smtp.east.cox.net
in /lib/ndb/local/.

ok, this is what I have in the last line of /mail/lib/rewrite:

# send all mail to the gateway or mail server, $smtp,  for delivery
([^!]*)!(.*) 		| 		"/mail/lib/qmail '\s' 'net!smtp.gmail.com'" "'\2@\1'"

net!$smtp, perhaps?

Try:

	ndb/ipquery sys $sysname smtp

This will print smtp=my-gateway-server
If this is wrong or fails perhaps you edited /lib/ndb/local
and didn't refresh cs with:

	echo -n refresh >/net/cs


Also, there is still a problem in the dns client cache which has not
been tracked down yet, try doing a lookup of you destination's
IP address before sending the email:

	ndb/dnsquery my-gateway-server

If this is successfull you can add a line as to /mail/lib/rewrite
as a workaround:

	echo my-gateway-address | ndb/dnsquery > /dev/null
