Sendmail daemon is inactive, but still i can send emails
Hi,
I did setup sendmail on one of AIX LPARs. Its working as expected. But, would like to clarify something with you all.
I stopped the sendmail daemon on AIX LPAR, now it is inactive(&commented it on /etc/rc.tcpip ). But still, am able to send the emails even after stopping daemon.
As per my understanding;
in order to "send" mail, the mail server is not required to accept connections on port 25 or any other port. Listening mail server is used for receiving mail.
is that correct ?
if yes, so i can disable the sendmail daemon on aix forever right ?
another question is
i see some error/entry in mail logs all the time.but, I do not see this error after stopping the sendmail daemon.
Code:
"
Jan 1 10:10:10 AIXLPAR mail:info sendmail[1234567]: xxxxxx4: to=myuser.name@domain.com, ctladdr=root (0/0), delay=10:10:39, xdelay=00:02:15, mailer=esmtp, pri=35000, relay=domain.com., dsn=4.0.0, stat=Deferred: Name server: domain.com.: host name lookup failure"
Please let me know, if this error can be ignored.
