Bad News here

It's common practice to block mail servers from private internet connections with dynamically assigned IP addresses. You'll have a lot of rejections for valid mails. Nothing you can do about it. Fighting Spam means making it hard for spammers to send emails - at the same time making it hard for everybody to send emails.

And don't even try to send mails without a proper set up mail server(rdns, SMTP-Banner, Relay-Restriction,...). Connection will be dropped, faster than your mailer can say HELO.

IMO is using a smarthost one of the easier alternatives here.

Email::Send::SMTP(3pm)					User Contributed Perl Documentation				    Email::Send::SMTP(3pm)

NAME
Email::Send::SMTP - Send Messages using SMTP SYNOPSIS
use Email::Send; my $mailer = Email::Send->new({mailer => 'SMTP'}); $mailer->mailer_args([Host => 'smtp.example.com:465', ssl => 1]) if $USE_SSL; $mailer->send($message); DESCRIPTION
This mailer for "Email::Send" uses "Net::SMTP" to send a message with an SMTP server. The first invocation of "send" requires an SMTP server arguments. Subsequent calls will remember the the first setting until it is reset. Any arguments passed to "send" will be passed to "Net::SMTP->new()", with some exceptions. "username" and "password", if passed, are used to invoke "Net::SMTP->auth()" for SASL authentication support. "ssl", if set to true, turns on SSL support by using "Net::SMTP::SSL". SMTP can fail for a number of reasons. All return values from this package are true or false. If false, sending has failed. If true, send succeeded. The return values are "Return::Value" objects, however, and contain more information on just what went wrong. Here is an example of dealing with failure. my $return = send SMTP => $message, 'localhost'; die "$return" if ! $return; The stringified version of the return value will have the text of the error. In a conditional, a failure will evaluate to false. Here's an example of dealing with success. It is the case that some email addresses may not succeed but others will. In this case, the return value's "bad" property is set to a list of bad addresses. my $return = send SMTP => $message, 'localhost'; if ( $return ) { my @bad = @{ $return->prop('bad') }; warn "Failed to send to: " . join ', ', @bad if @bad; } For more information on these return values, see Return::Value. ENVELOPE GENERATION The envelope sender and recipients are, by default, generated by looking at the From, To, Cc, and Bcc headers. This behavior can be modified by replacing the "get_env_sender" and "get_env_recipients" methods, both of which receive the Email::Simple object and their only parameter, and return email addresses.
