sendmail problem

[Ronelle van Niekerk]

We can't seem to send mail to any of the users on the machine except root.

If root send a mail to the users, it gets a message back saying "User Unknown"

Any ideas?
I am sendmail illiterate.

sendmail is fun.

check the /etc/mail/aliases file for entries that would confuse sendmail.

try this diagnostic

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

.



you'll get a better idea whats wrong.

whence sendmail to get the full path in case you get a not found message.

mailq

shows mail waiting for delivery.

I bet you have a DS directive in /etc/mail/sendmail.cf

That tells the server to relay all mail, but local users are still not supposed to go outside

Hmm. I'd like to see some diagnostic posts.

Can u check and see if all your mails (that you tested ) can be seen in mailq.

Did you make any changes recently? If Yes, what changes.

Thanks guys,

we ran the sendmail -v -d8.99 -d38.99 username command and it came up with something very interesting:

seq_map_lookup(aliases, sabpmgr)
seq_map_lookup(aliases.files, sabpmgr)
impl_map_lookup(Alias0, sabpmgr)
db_map_lookup(Alias0, sabpmgr)
sabPmgr... User unknown

The username is sabPmgr.
Can sendmail handle caps in user names?
