Randomly fails to return from try_to_sendmail call.

[geekdad1]

I have a perl script run from a web form that create 1 to n emails. I was hoping Email::Sender would be more efficient than calling sendmail directly. However I have a problem in that the email sometimes go and other times they fail to return and the script times out.

here is a partial program sample:
use Email::Sender::Simple qw(try_to_sendmail);
use Email::Simple;
use Email::Simple::Creator;
use Data::Dumper;
use CGI;
$q = new CGI;
...
my $to = """ . $user{user_name} . "" <$user{email}>";
print "sending to $to\n";
my $msg = Email::Simple->create(
header => [
To => $to,
From => '[email protected]',
Subject => 'Login for PharmaNet',
],
body => $body,
);
print Dumper($msg);
my $res = eval {
try_to_sendmail($msg);
};
print "sent $res\n";

Here is the output from a failed attempt:
sending to "Emergency, Demo Account" [email protected]
$VAR1 = bless( {
'body' => 'You have requested a password reset
on 2016/05/04 10:56:05.

It should get to the sent $res statement but it doesn't

There is nothing in the webserver logs to suggest there is a problem, other than it will quit once the timeout occurs.
I just downloaded the most recent version through CPAN.
I'm running an Apache web server and a pretty standard sendmail.

Is there something obvious I'm missing?
