Hi.



I need to send mail from a linux machine to a remote mail server. I've
managed to send an email by means of a telnet to port 25 of the mailhost,
but so far I haven't been able to properly configure sendmail, so that it
relays the emails to the mailhost.



Here is the output of the mail command:



[root@(protected) mail]# mail -v -s Test iecisa.cortegag@(protected)

Test

.

Cc:

iberia.es: Name server timeout

iecisa.cortegag@(protected) Transient parse error -- message queued for
future delivery

iecisa.cortegag@(protected) queued



It seems that the domain iberia.es can't be resolved, and the message does
not leave the local machine.



I've read some information about configuring sendmail, and have tried
adding:



define(`SMART_HOST',`mailhost')



in the /etc/mail/sendmail.mc file (mailhost is properly defined in the
/etc/hosts file). I've used the m4 macro to generate a new sendmail.cf file,
and have restarted sendmail. I keep getting the same error.



Can anybody help me?



Thanks in advance.
