A perl question!
This is really just out of curiousity as I know the solution. We have a section
of code that has been working fine using MIME::Lite that reads as follows:
$msg = MIME::Lite->new(
From =>SMTP_FROM_ADDRESS,
To =>$email_list,
Subject =>$subject,
Type =>'TEXT',
Data =>$message_lines
);
if($file_name)
{
my($name,$path,$suffix) = fileparse($file_name);
### Attach a part:
$msg->attach(Type =>'spreadsheet/xls',
Path =>$file_name,
Filename =>$name
);
}
## Configure Mime to send via SMTP
MIME::Lite->send('smtp', SMTP_HOST, Timeout=>60);
if (! $msg->send())
{
print STDERR "Unable to send email:$!\n";
}
Someone on the $email_list left the company, their email address became defunct
and the above section of code failed. Taking them out of the distribution list
made the code work again.
My question is: how/why did MIME::Lite know to fail?
My preconception is the email would be sent to an email queue that, at some
point in the future, would attempt to get the email to the target address - at
which point an email would be sent back reporting the failure. Immediate
failure suggests the target address was either checked interactively or was
cached somewhere as being defunct.
I am also wondering if it is even desirable for the above code to fail.
Thoughts/explanations?
Chris
