Using SMTP Pro and Ebizmarts’ MailChimp extension in Magento

September 18, 2011 in Magento, SMTP Pro Magento Extension with 7 Comments

This is just a quick blog post that will hopefully help people facing the clash in Magento between my SMTPPro email extension and Ebizmarts’ MailChimp extension.

The clash occurs only in one class Mage_Core_Model_Email_Template which we both override to extend the default Magento email sending capability.

Because it only makes sense to use either SMTPPro or MailChimp as your ESP if you want to use SMTP Pro you can safely disable the MailChimp core class override and then SMTPPro will send the store emails using whichever method you have configured.

To remove the core override edit code/local/Ebizmarts/Mailchimp/etc/config.xml and remove the following XML:

<core>
    <rewrite>
        <email_template>Ebizmarts_Mailchimp_Model_Email_Template</email_template>
    </rewrite>
</core>

When/Why is this safe to do?

You can do this when you are not using the MailChimp STS capability and want to use SMTPPro to send your emails. If you don’t want to send via SMTPPro, just uninstall it to resolve the conflict.

You can see in the first lines of the override class Ebizmarts_Mailchimp_Model_Email_Template why this is safe:

if(!Mage::helper('mailchimp')->isStsActivated()){
    return parent::send($email, $name, $variables);
}

This means that if you are not using STS, then the whole override is basically a noop.

One caution I have for you though, once you modify an extension, you have to remember to apply the same patch each time you upgrade it, otherwise the clash will creep back in!

Update: I missed some emails notifying me of comments, I missed this fairly important one from Ebizmarts with basically this fix in it… On a related note, if I didn’t reply to your comment for the last few weeks, that’s why.

SMTP Pro with Magento: A sort-of user guide.

June 30, 2011 in Google Apps Email Magento Extension, Magento, SMTP Pro Magento Extension with 61 Comments

This blog post is about the SMTP Pro extension. It is my attempt at full explanations to some very good questions/feedback from Chris Last in his comment on an earlier post. I decided that I should give thorough explanations to the questions and they probably belong in a blog post rather than a reply comment. Hopefully it’ll form a mini user-guide, I’ll try to update it as such over time.

There are too many sections in Config->Advanced->System for me to make complete sense of:

Mail Sending Settings – do these have any effect?
Disable Email Communications No
Host localhost
Port (25) 25
Set Return-Path no

1) The Mail Sending Settings are the built in Magento ones, they don’t work very well for custom SMTP servers and you can safely ignore them. One thing to note though. I do adhere to their disable configuration in my extension. So if you disable all emails using the core config here, all emails do stop even if sending via SMTP Pro.

Magento 1.5.0.1 and SMTPPro 1.4.2 Now Working – Free Gmail/SMTP, ahoy!

March 7, 2011 in Google Apps Email Magento Extension, SMTP Pro Magento Extension with 13 Comments

There have been several reports of my SMTP Pro email extension failing on Magento 1.5. I hadn’t tested or recommended installing it on Magento 1.5 and wasn’t going to for a little while. You could say I’m not really an early adopter when it comes to Magento versions.

However, the ever helpful Rhonda (@rondata) from Magento got in touch with me late last week to report there may have been a packaging problem with my extension that has made it unable to be used on the new Magento Connect. So I thought if I was going to repackage it, I may as well also fix it up for Magento 1.5 – and so here is SMTPPro version 1.4.2.

As always you can download the package manually here (or via Magento Connect) to check it out before you install it manually.

I have tested the extension on Magento 1.4.2 and 1.5.0.1, also tested a Magento Connect install on 1.5.0.1. Everything seems to be in order. The change in 1.5 was a move to array based email addresses and names in the Email_Template class.

I still feel like it’s shoddy OO that I have to override an entire method and duplicate all the logic in it just to swap in my SMTP transport configuration. For those that care, I did try some techniques to avoid it, but the default transport is explicitly set by the core code if a return path is set, which invalidates anything I can do in a subclass – short of temporarily hijacking the return path configuration, which I may resort to doing in the next release.

In the process of testing a Magnto Connect install I did see a very cool feature in the latest Magento, and I may just have missed it in the earlier releases as I seldom use Magento Connect anymore.

Upload a Package directly

Installing a package directly from within the downloader module will surely make the day of many commercial extension developers – at least until they can sell extensions directly on Magento Connect*.

Anyway, that’s about it – the new version supports 1.5, and can be downloaded/installed on Magento Connect. Go enjoy some free SMTP/Google Apps/Gmail email sending! Please let me know if you have any problems or spot any bugs.

* Speaking of which, I wonder what % Magento will take… Apple set a pretty high benchmark at 30%. Magento doesn’t quite have the same kung-fu grip on distribution though so maybe it’ll be lower.

Latest version of SMTP Pro Finally Uploaded to Magento Connect

July 25, 2010 in Google Apps Email Magento Extension, Magento, SMTP Pro Magento Extension with 45 Comments

Geez it’s been a long time coming thanks to Invalid package.xml format errors and duplicate maintainers and goodness-knows-what else. You can finally get the latest version of SMTP Pro – 1.3.4 – even though it’s identical to 1.3. (thank Magento Connect…).

For those who want to install the Magento extension manually (and if you are engineering Magento you probably should) – you can get version 1.3.4 of SMTP Pro here.

If you read my last post on the improvements, you’ll know that it has some great new features for sending, and logging email in Magento using either SMTP or Gmail/Google Apps. So please give it a try and let me know what you think.

New SMTP Pro Magento Email extension released

June 4, 2010 in Google Apps Email Magento Extension, Magento, SMTP Pro Magento Extension with 72 Comments

I’ve had a chance to make a couple of improvements to my SMTP Pro email extension for Magento. Both changes are not exactly life altering, one adds extra error detection to the self-test, and the other fixes a header problem with the self-test (reported by Phil). More details follow about the changes, if you want to get the extension, download SMTP Pro on Magento Connect. (Updated: finally on Magento Connect!)

I now send a real live contact form message as part of the testing – and ensure that when the email sends, my extension code is actually being called. I’ve had a lot of people reporting problems with emails not sending lately, only to find it’s because some other extension is interfering with my email sending. This tweak to the self test will help identify those issues.

This is implemented as a static variable on the self test controller, that is set before sending the test email and then altered by the email observer (if it is called as expected):

// Now we test that the actual core overrides are occuring as expected.
// We trigger the password forgot email, as though a user had done so.
 
self::$CONTACTFORM_SENT = false;
$this->_sendTestContactFormEmail();
 
// If everything worked as expected, the observer will have set this value to true.
if (self::$CONTACTFORM_SENT) {
	$msg = $msg . "<br/> Contact Form test email used SMTPPro to send correctly.";
} else {
	$success = false;
	$msg = $msg . "<br/> Contact Form test email did not use SMTPPro to send.";
}

and the code in the observer that alters this variable:

// For the self test, if we're sending the contact form notify the self test class
if($event->getTemplate() == "contacts_email_email_template") {
        include_once "app/code/community/Aschroder/SMTPPro/controllers/IndexController.php";
        Aschroder_SMTPPro_IndexController::$CONTACTFORM_SENT = true;
}

The other change was trivial, adding a ->setFrom() call when sending the test email. Thanks to Phil for pointing that out.

Lastly, Eric requested a useful feature which I will add, but I haven’t had time to put that in to this release, next time!

Let me know any feedback you have on the changes, or if you’re having trouble sending emails in Magento – feedback welcome.
