I as trying ot make a simple script for a friend and it needs the ability to E-mail. I didn't to have to make him install the smtp server module so I decided to do the SMTP primitively. I can't figure out why the end of message dot is not working. This script was built for Activestate PERL. Does anyone know why it fails? It works from the a terminal connection to port 25. I can't figure it out.

#!/usr/bin/perl -w
use IO::SOCKET::INET;

##CALL IP FROM SYSTEM##
$ipconfig=`ipconfig`;
$ipconfig=~/(.*IP.*\: )(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})/;


##CHECK IF CURRENT IP IS SAME AS LAST IP##
open(LAST,">last_ip_info.txt") or die "couldn't open last status file.
+  reason:$!\n";
@last=<LAST>;
close(LAST);
#if($last[0]eq$2)
    #{
    #    print 'current IP is the same as last IP';
    #}
    #else
    #{
        &mail_ip($2);
    #}
    

##PRINT OUT CURRENT IP##
#print "IP\:"."$2".":IP\n";
open(LAST,">last_ip_info.txt") or die "couldn'topen last status file$!
+\n";
print LAST "$2\n";
close(LAST);

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
