trouble sending email with mail::mailer

[badperson]

Hi,
I'm trying to write a script that will send an email, but I'm getting an error:


use strict;
use Mail::Mailer;

my $mail = Mail::Mailer->new("sendmail");
$mail->open({
From => 'my@address.com',
To => 'my@address.com',
Subject => 'test email',
}) or die "can't open $!\n";


returns this:

No mailer type specified (and no default available), thus can not find executable program. at test-email.pl line 4


by altering the code like so:

my $mail = Mail::Mailer->new qw(mail);

I get

Can't locate Mail/Mailer/mail.pm in @INC (@INC contains: /bunch/of/paths/for/@INC

what is the correct way to configure this for ubuntu?

You must not have a Message Transfer Agent (http://en.wikipedia.org/wiki/Message_transfer_agent) installed. Your "sendmail" example generates that error if it cannot find a sendmail executable. Install one of the available MTAs, like the postfix package. http://packages.ubuntu.com/lucid/postfix

thanks for the reply.
I installed sendmail, and my script now sends email, although the script runs very slowly. I think this is because sendmail doesn't like sending email to/from the localhost?

my mail.log file has entries such as:

do you know how to configure sendmail to work faster, or is postfix a better solution?

Do you have a fully qualified domain name for your system? I think it's trying to figure that out for the minute's delay. Try adding "jason-desktop.example.com" as an additional name to the "jason-desktop" entry in /etc/hosts. Or try postfix.

how do you connect postfix to mail::mailer?
I'm getting this when trying to use the default MTA:


No real MTA found, using 'testfile' at /usr/share/perl5/Mail/Mailer.pm line 107.

tried restarting postfix...no dice.
