sendmail problem
we have RH 9 with sendmail, apache and php, In php we use it to send email, like welcome email and etc.

Our emails are autmatically relayed to our mail server, from our Main Network(we are just a department), i'll name the mail server as
mailserver.domain.com, but looking at my sendmail.mc ( mailserver.domain.com doesn't exist) and my experience before a fresh installation can automatically use the mailsever.domain.com as a relay server(maybe im just too noob)

problem now, is that the mailserver.domain.com is block when I telnet to it at port 25 It cannot pass through, the admin says that we should use the other mail server that is we are connected now, so their is the new mail server I named it newmailserver.domain.com, I was able to telnet it and send password.

Now my problem is how to make that new mail server be used by sendmail, I did try to modify sendmail.mc and uncomment the smart host, and added the new mail server.

Now Im having another weird things on my maillog

Quote:
version=TLSv1/SSLv3, verify=FAIL, cipher=DHE-RSA-AES256-SHA, bits=256/256

relay=newmailserver.domain.com. [***.**.170.16], dsn=5.6.0, stat=Data format error
Any clue what should I do next? (ahem my story is a little long one)

etrn

System Administration Commands				 etrn(8)

NAME

     etrn - start mail queue run

SYNOPSIS

     etrn [-v] server-host [client-hosts]

DESCRIPTION

     SMTP's  ETRN  command  allows  an	SMTP client and server to
     interact, giving the server an opportunity to start the pro
     cessing  of  its  queues for messages to go to a given host.
     This is meant to be used in start-up conditions, as well  as
     for mail nodes that have transient connections to their ser
     vice providers.

     The etrn utility initiates an SMTP  session  with	the  host
     server-host  and sends one or more ETRN commands as follows:
     If no client-hosts are specified, etrn looks up  every  host
     name  for	which  sendmail(1M)  accepts  email and, for each
     name, sends an ETRN command with that name as the	argument.
     If  any  client-hosts are specified, etrn uses each of these
     as arguments for successive ETRN commands.

OPTIONS

     The following option is supported:

     -v    The normal mode of operation for etrn is to do all  of
	   its	work  silently.   The -v option makes it verbose,
	   which causes etrn to display  its  conversations  with
	   the remote SMTP server.

ENVIRONMENT

     No environment variables are used.

FILES

     /etc/mail/sendmail.cf	      sendmail configuration file

SEE ALSO

     sendmail(1M), RFC 1985.

CAVEATS

     Not all SMTP servers support ETRN.

CREDITS

     Leveraged from David Muir Sharnoff's expn.pl script.  Chris
     tian von Roques added support for args and fixed a couple of
     bugs.

AVAILABILITY

     The  latest  version  of  etrn  is  available in the contrib
     directory of the sendmail distribution through anonymous ftp
     at ftp://ftp.sendmail.org/ucb/src/sendmail/.
