mailq

is mail queuing and not geting on the box.

sendmail -v -q

process the mail queue.

ps -ef | grep sendmail

Is the daemon running?
/etc/rc.config.d/mailservs

Is the SENDMAIL_SERVER=0 or 1

1 means start sendmail.

To manually start the daemon.

/sbin/init.d/sendmail start

Diagnostics:

sendmail -v -d8.99 -d38.99 someone@some.net
type some text

.

good diagnostics.

Permissions are not correct in the /var/spool/mqueue folder.

Also, probably problems in /var/mail

the mqueue folder needs to be owned by bin and the owner needs write permissions on it.

drwxr-xr-x /var/spool/mqueue

That someone@someone.net needs to a real email address. Sorry I didn't make that clear.

It appears you do have good dns resolution. Once the permissions problems are resolved, mail should go through.

check the file /var/adm/syslog/mail.log for more information on this issue.

the path queue is /mail/mqueue

ls -ld /mail
drwxr-xr-x 7 smmps smmps 512 Oct 25 16:49 /mail

ls -ld /mail/mqueue
drwxr-xr-x 2 root smmps 2550272 Nov 18 16:35 /mail/mqueue

Does the inability to connect correspond at all to system load? If your system gets to (or close to I believe) 100% busy, sendmail will stop accepting connections.

If its a performance issue, the scripts I'm attaching will help you spot the issue.
