May  2 04:06:15 lon.mail.net exim[17905]: 2012-07-03 07:06:15 1SPPtO-0004en-PS <= me@ours.co.uk H=smtpout.mail.com [22.5.10.4] I=[6.5.14.4]:25 P=esmtp S=13333 id=6aeca3b79b8892d6105dab131c76f066@localhost.localdomain T="Half price offer"

I want to grab the IP address ( 22.5.10.4 without the square brackets ) the email address ( me@ours.co.uk which always follows <= )

so far I have the ip address but with the square brackets using :

my ($srvrip) = $remainder =~ m/H=.+?(\[.+?\])/;

How can I extract the email address ?

I have a lot of lines in the log files so need this to be as efficient as possible and am also restricted to perl 5.8.4

Hope you can help
