<div dir="ltr">I'll add that you should look into a transactional email partner
like sendgrid, mailgun, etc. They'll help you stay out of the
black lists by showing you what not to do, ans how to set up DKIM, etc.
for authentication of your email.
<div><br></div>
<div><br></div>
<div>I use sendgrid professionally, with one of my cusotmers that sends a lot
of email.</div>
<div><br>
<div>If your volume is under 10k emails per month, sendgrid is free, and they
have a templating feature which allows you to upload a template
(parameterizable) and let them to the mail merge on their servers, for up to
one thousand addresses per tx.</div>
<div><br></div>
<div>So instead of generating 3000 emails and pushing them through your smtp
server, you'd upload the template file, and push three 1000-name lists to to
sendgrid and let them take care of delivery. Something to think
about.</div>

emails.</div>
<div><br></div>
<div><font size="2">Hello,</font></div>
<div><font size="2"></font> </div>
<div><font size="2">You lot are all experts at Catalyst and
Perl,</font></div>
<div><font size="2">and because I'm using Perl to code a Catalyst program,
I wanted to ask you about a problem I've encountered.</font></div>
<div><font size="2"></font> </div>
<div><font size="2">The Catalyst app I'm coding is to replace a PHP
website, which presently allows an admin to manage sending out an email
to all members. The site has 3000 odd members. From what I could tell,
the PHP code was simply using the PHP mail function to send email
(although it did in my experience typically take two days for everyone
to receive an email sent with it).</font></div>
<div><font size="2">I've also been asking other Perl programmers when I've
had the chance - and the only concerns raised, were about IP
blacklisting or emails bouncing back - not about actual code
working.</font></div>
<div><font size="2"></font> </div>
<div><font size="2">So could sending 3000 emails be as simple as Matt's
old CGI form mail?</font></div>
<div><font size="2"></font> </div>
<div><font size="2">I had a look on CPAN, and found the simple looking
Email::Stuffer,</font></div>
<div><font size="2">and wrote a script, sending an email to myself,
and it worked.</font></div>
<div><font size="2">I then modified the script to pick five email
addresses from a MySQL database, and email them, and again - it
worked.</font></div>
<div><font size="2">Okay - one final change - throwing 3000 email
addresses at it.</font></div>
<div><font size="2">How does that do....?</font></div>
<div><font size="2">Starts to work - then throws up an Internal
Server Error in the browser window,</font></div>
<div><font size="2">and I find out my Fast CGI Plack Up server thingie
isn't up, nor running my Catalyst app anymore.</font></div>
<div><font size="2">I have to type plackup and my details, etc, again from
the command prompt.</font></div>
<div><font size="2">A log in to Web Host Manager (this is an apache2 VPS
with CPanel) and a check of the "View Sent Summary" shows 1020 emails
sent - 611 successful, 642 deferrals and 329
failures...curious, as that adds up to more than 1020, =S. If I click
through for more details, it shows 1582 records - some with green ticks,
and others with amber or red exclamation marks, ^_^.</font></div>
<div><font size="2">I can worry about IPs and failure rates
later....</font></div>
<div><font size="2"></font> </div>
<div><font size="2">....I just want to know why the whole FastCGI Plack
loaded Catalyst app came down half way through,</font></div>
<div><font size="2">and how I can have a Perl script process sending 3000
emails without that happening every time, =S.</font></div>
<div><font size="2"></font> </div>
<div><font size="2">Do I need to use a queue within Perl? Or does the
postfix/sendmail on the server, automatically queue everything for me?
If so - why did my code crash the Catalyst app, and not send all
the emails? >_<.</font></div>
<div><font size="2"></font> </div>
<div><font size="2">I'm guessing this is a common problem - how does a
website email all its signed up members - and so there must surely be a
common solution among Perl / Catalyst users....?</font></div>
<div><font size="2"></font> </div>
<div><font size="2">Any help, appreciated!</font></div>
<div><font size="2"></font> </div>
<div><font size="2">Yours,</font></div>
<div><font size="2">Andrew.</font></div>
