Don't know what you're doing exactly, but it sounds that the script wants the name of a machine running sendmail. Safest bet is to run sendmail or postfix and to point the script at localhost.

i want to run sendmail with the machine that the script is running on here is a piece of my script:
-------------------------------
my $mail_relay = "localhost";
my $mail_from = "ron.srnka\@winner-net.com";
my $mail_to = "ron.srnka\@winner-net.com";

my $smtp = Net::SMTP->new($mail_relay, Hello => "helo there") or die ("errrr");
--------------------------------
instead of localhost i have tried :
www.winner-net.com
www.winner-net.uk.com
winner-net.com
winner-net.uk.com

these are meaning less to you but anyway, it always dies when Net::SMTP->new is run...

So check if you've got sendmail or postfix up and running on that machine. Try telnetting into port 25 and getting a reply.

Hmm. Running out of clues here. Anything in the logfiles? If you use this to send to a local user, does it arrive?

Just wondering.

log files! i never knew i am learning a damn lot from you thanks a lot anyway here are the results of your input/suggestions:

if i send to a local user it does get delivered:
and generates the following log(i dont think this is the whole transaction):

Aug 20 18:16:37 WINNERNET-01 sendmail[7241]: h7KHF4807152: to=maint@localhost, ctladdr=maint@localhost (501/501), delay=00:00:14, xdelay=00:00:00, mailer=local, pri=30009, dsn=2.0.0, stat=Sent



when i use the script if generates some entries in the log file here is a few piesce:

Aug 20 18:19:45 WINNERNET-01 sendmail[6672]: h7JEKun05151: to=ron.srnka@winner-net.com, ctladdr=apache (48/48), delay=1+02:58:49, xdelay=00:00:00, mailer=esmtp, pri=300049, relay=thsmtpb1.byworkwise.com., dsn=4.0.0, stat=Deferred: Connection timed out with thsmtpb1.byworkwise.com.

AND

Aug 20 18:19:45 WINNERNET-01 sendmail[6672]: h7JEKun05151: to=ron.srnka@winner-net.com, ctladdr=apache (48/48), delay=1+02:58:49, xdelay=00:00:00, mailer=esmtp, pri=300049, relay=thsmtpb1.byworkwise.com., dsn=4.0.0, stat=Deferred: Connection timed out with thsmtpb1.byworkwise.com.

it looks like it is using something else to do the relay?
but i do not understand why it keeps on timing out.

i am leaving work now(I am in South Africa it is 7pm now)
so i will check any responses first thing in the morning

Thanx

Here is the whole log entry of an attempt to send:

the first part starts the process and the 2nd is the timeout 10 minutes later

Aug 20 18:20:23 WINNERNET-01 sendmail[7483]: h7KHKN807483: from=<ron.srnka@winner-net.com>, size=90, class=0, nrcpts=1, msgid=<200308201720.h7KHKN807483@WINNERNET-01>, proto=ESMTP, daemon=MTA, relay=localhost.localdomain [127.0.0.1]Aug 20 18:30:23 WINNERNET-01 sendmail[7485]: h7KHKN807483: to=<ronsrnka@hotmail.com>, delay=00:10:00, xdelay=00:10:00, mailer=esmtp, pri=30090, relay=mx4.hotmail.com.

Don't worry too much about that relay word. It does seem however that your sendmail is unsuccessful in talking to any outside mailserver. That does not increase its usefulness.

Could it be you have outgoing connections on port 25 blocked by any chance? (perhaps your company has blocked it on the firewall, I don't know. In that case, use the company mail server as a relay host instead. You never know :-)) Have you used sendmail on this machine successfully before (to send mail to the world, that is.)

cheerio,

René
