A simple example of sending mail using telnet. this sends mail to
[EMAIL PROTECTED] The bits you send are in braces {},
you do not type these!! Some hosts may be more fussy, they check that the
hostname you give and the IP address match, and may only accept mail from a
restricted list of hosts. sendmail configuration is a black art all by
itself.
<SNIP>
{telnet remotehost.domainname.com 25}

Subject: RE:Sending a mail using telnet 25 smtp(OT)
Hi Everyone,
This is an off topic question. But i am curious
to know the solution and so please no flames!!!
Few days back (6th july to be precise) Anton and
George S Pereira were discussing that anyone can send
mails using the telnet 25 smtp. Can someone elaborate
on this. I mean what will you do to avoid this in your
mailserver.
Waiting for your replies/flames in anticipation
;- )
Takara
