mail problem

[Steven E. Protter]

If that server is real then the User has been deleted.

This is a typical tactic to stop spam. I've recently been forced to remove one of my dearest aliases because it was getting 50 messages a day.

sendmail -v -q

that will try and force the queue with verbose messages.

sendmail -v -d8.99 -d38.99 address
type some text

.


This will max out your diagnostics.

looks like the host is resolving and the mail server doesn't know the user or is misconfigured.

hi,

please allow me to comment:
"rauthanms.external@infineon.com... User unknown"

can you try to send it to another valid and confirmed user on that same domain?
e.g.
sendmail -v -d8.99 -d38.99 postmaster@infineon.com

this will confirm that there is no problem with the email addresses...

regards
Yogeeraj

Waiting for your reply,

I have seen this problem before.

I have found that, even though I edit nsswitch.conf, mail doesn't get the new resolution order. SAM fixes it somehow. Someday I will look into what SAM does.

Go into SAM, Network and Communications, Name Service Switch. Select hosts, then configure the menus so that resolution occurs the way you expect it to.

[Bill Hassell]

This may be due to newer versions of sendmail that try to validate hosts--sendmail bypasses /etc/nsswitch.conf and follows the policy set in the /etc/mail/service.switch file. Set the two values to:

hosts files dns
aliases files

sendmail is getting fairly convoluted about hostname resolution and mail delivery.

And then there are the MX records (or not) in your DNS server. When sendmail gives up on a hostname, see how it will figure out where to send the mail for a given destination:

nslookup -type=mx infineon.com
