sendmail configuration

[grob115]

Am having difficulties in using sendmail to send a test mail to Hotmail via SpamArrest.

smtp<dot>spamarrest<dot>xxx uses port 587. Added the following two lines to sendmail.mc

define(`RELAY_MAILER_ARGS', `TCP $h 587')dfl
define(`ESMTP_MAILER_ARGS', `TCP $h 587')dfl

I then run "make", and "service sendmail restart", then got the following when I attempted to send mail.

Jun 20 02:36:54 devsvr sendmail[3298]: o5JIasDR003298: from=root, size=232, class=0, nrcpts=1, msgid=<201006191836<dot>o5JIasDR003298<at>devsvr<dot>xxx>, relay=root<at>localhost

This is from /var/spool/mail/root upon sending the mail.

----- The following addresses had permanent fatal errors -----
<xxxx<at>hotmail<dot>xxx>

Anyone has a clue of what I need to do? I'm lost!

You can try to add your domain in to /etc/mail/relay-domains file. if it doesn't exist. you can create it.

Based on your suggestions, I found this site (the best explanation so far on sendmail).
www<dot>linux homenetworking<dot com>/wiki/index<dot php>/Quick_HOWTO_:_Ch21_:_Configuring_Linux_Mail_Server s]Quick HOWTO : Ch21 : Configuring Linux Mail Servers - Linux Home Networking

However, despite having set all these resolv.conf, and hosts files, it still doesn't work. It does, however, stop putting a mail in my /var/spool/mail/root saying relay access denied.

The /var/log/maillog prints out that it is simply timing out with smtp.spamarrest.com. Then when I typed "mailq" I see each of the mail I tried to sent without success. Not sure what's wrong.

I tried to "telnet smtp.spamarrest.com 587" and it returns a message saying ESMTP so it works.
