Hi All,

Been using Perl for a long time, but tonight something has me beat.

I am trying to capture certain IP's from mail log lines, and this all worked well until I changed the code a bit to capture a new match. For some reason, this code here:

#!/usr/bin/perl -w

my $line = "May 25 10:44:06 postfix/smtpd[6992]: NOQUEUE: reject: RCPT
+ from 13-34-221-131.virtuals.cl[131.221.34.13]: 454 4.7.1 <eax_64@yah
+oo.com>: Relay access denied; from=<xo@ore.net> to=<eax_64@yahoo.com>
+ proto=ESMTP helo=<192.168.0.133>";


      if  ($line =~ /Relay access denied/) {
      $line =~ s/.*\]: //;
#print $line;
      $line =~ s/.*\[//;
      $line =~ s/\].*//;
      chomp($line);
print $line;
}

matches the second ']:' first, and fubars the whole logic.

I have tried researching this, but got nowhere due to the noise.

Any ideas what is going on?

Thanks,

Nick

P.S. I fixed it up another way, but I am intrigued.
