Detect image rendering in email - html-email

I know that services like SendGrid already have built-in plugins for this. But I want to build my own, custom, module for this.
Reason why I am doing this is my application uses several different smtp servers specified by user.
Is it even feasible to create one module for different smtp servers?

Absolutely! It's relatively simple too, at the most basic level you do the following:
Assign every email you send a unique id, in the email place a reference to a script on your server with the unique id. (e.g. <img src="https://example.com/img?id=1 >)
When /img?id=N is called have your code log the id and then serve the image.
A more concrete example in PHP would look something like:
Mail Sender:
$img = '<img src="https://example.com/img.php?id=' . generate_email_id() . '">';
mail("test#example.com", "This is a test.", "Hello! I hope this test works!" . $img);
img.php:
log_email_by_id($_GET['id']);
header("Content-type: image/jpeg");
readfile("pixel.jpg");

Intercept all Joomla outgoing emails & reroute them to a specified address

I'm working on a new Joomla site and am working on testing outgoing email. I'd like to be able to intercept all outgoing emails and reroute them to an address I specify. It is very useful in development when you have a copy of a live site with thousands of users, so email does not go to real users from the copy site.
It would be great to do this with a extension but have been unable to find one to do some. I'm also open to getting this done on the server side if necessary.
I found a Drupal module that does exactly what I'd like to do except it's obviously for Drupal and note Joomla.
https://drupal.org/project/reroute_email
On Joomla-Level you could create a system plugin that loads up own, monkey-patched JMail class.
I'm not sure if you would be able to extend the original JMail because of namespace conflict, so maybe you'd have copy it over and alter the addRecipient method:
public function addRecipient($recipient, $name = '')
{
$this->add('custom#email.com', 'custom name', 'AddAddress');
return $this;
}

load magento email template

I'm using my own code to send out SMS's to the customers at the same time as the emails go out. I do this by getting the email template code with
$code = $this->getTemplateCode();
and then trying to load the corresponding SMS template with
$sms = $this->loadByCode('sms_'.$code)->getTemplateText();
I then check if $sms is empty before proceeding to send the text, meaning that I can add or remove connected SMS templates at will. The problem I'm having is that I sometimes, when there is no connected "sms_*" template, I get the full email sent out as the SMS instead of no text being sent.
I've debugged the code by sending out the template it tries to load as the actual SMS, and received "sms_creditmemo", but when I instead load it with the method above and do a var_dump($sms); exit;it shows me that it loaded the template "creditmemo_invoice" which is the email template I use instead of "creditmemo" when the payment method is detected. I make sure to use the original template string in $code (used to load SMS template) no matter the payment method.
Now my question would be how this can even be possible, does the loadByCode take best matching template or is there some other more serious bug I've missed, maybe there's better ways to load in the templates and make correct checks to see if they even exist?
I solved this by checking if the correct email template gets loaded with
if ($this->loadByCode($template)->getTemplateCode() == $template)

Force.com email service

I have created an email service in force.com.Can anyone help me out of how to use thta in apex classes.say,i wanna send mail when user registration is successful??
Many Thanks,
Sandhya Krishnan
I assume you want to send an email directly from Apex code, either in a Trigger or from a page controller ... ? If so, this page can get you started:
http://www.forcetree.com/2009/07/sending-email-from-your-apex-class.html
Clearly you don't want to hard-code your email template into your classes, so make sure to read at least through the part that shows how to look up the template dynamically. That should be enough to get you on your way.

How to send form contents anonymously via email

How do you send the content of a website form to an email address without disclosing the email address to the user.
Thanks!
PS: If at all possible, I would like this to be in HTML JavaScript Ok, anything I guess.
Not possible. You can however put a "fake" from header in the mail. You'll only risk it to end up in the junk folder.
HTML doesn't provide any functionality to send mails. You'll really need to do this in the server side. How exactly to do this depends on the server side programming language in question. In PHP for example, you have the mail() function. In Java you have the JavaMail API. And so on.
Regardless of the language used, you'll need a SMTP server as well. It's the one responsible for actually sending the mail. You can use the one from your ISP or a public email provider (Gmail, Yahoo, etc), but you'll be forced to use your account name in the from header. You can also register a domain with a mailbox and just register something like noreply#example.com and use this to send mails from.
Update: JavaScript can't send mails as well. Like HTML it's a client side language. You'll need to do it with a server side language. All JavaScript can do is to dump the entire page content back to the server side. jQuery may be useful in this:
$.post('/your-server-side-script-url', { body: $('body').html(); });
with (PHP targeted example)
$to = 'to#example.com';
$subject = 'Page contents';
$body = $_POST['body']
$headers = prepare_mail_headers();
mail($to, $subject, $body, $headers);
Update 2: if you actually want to hide the to header in the mail, then you'll need to use the bcc (Blind Carbon Copy) instead. This way the recipient addres(ses) will be undisclosed. Only the from, to, cc stays visible.
If you mean doing so on a client side, using mailto: link - you can not.
If you mean any way, yes - you submit the form contents back to your server, and have your back end script send the email.
You can do the form in HTML, but the posting will need to be done in a script. Even if you don't expose the email address, the script can be used to spam that email address. This is why you see captcha being used in such cases.
There are scripts available for most languages. Check to make sure their are no known security problems for the scripts. The original Matt's script in perl had problems, and the Perl community created a more secure version.

How to send an email from a webpage/webform?

What techniques are available for sending an email via a webpage or a form on a webpage?
I've got some background idea that you POST the form data to a script but I've don't really know what a cgi script is (I'd love to learn if this is the suggested method!) or what the current practice is.
This is just to provide some way for users to contact the operators. The in-page form seems like it would be easier on the user than ask them to open their mail client. I was also concerned about bots harvesting the contact email address (in the case of mailto: links).
When you submit a form, the data in that form gets sent to the server-side script. For example, in PHP you access that data with the $_POST array, the <input name=""> becomes the arrays index.. For example..
// <form action="mailer.php">[..]<input name="subject" [..]><input name="content" [..]></form>
echo("The subject is: ". $_POST['subject']);
echo("The content is:" . $_POST['content']);
At the most basic level, all you have to do is use your programming languages built in mail function. Again, in PHP this is simple mail():
mail($to, $subject, $message);
You would just set $to to your email address (Do not allow the user to set this, or they are able to send mail as "you", to anyone - "spam"..), $subject and $message would be set form $_POST[]
Before you go any have a HTML file that goes to a script with mail("me#example.com", $_POST['subject'], $_POST['content']);, think what would happen if someone reloaded that page 200 times.. You must have some kind of security in it, probably a captcha, and/or rate-limiting.
One thing, that has bugged me before - remember a "contact us form" is not a replacement for giving an actual email address! For example, my mail client keeps a copy of all mail I send, and I can attach files, and it's much nicer writing in a familiar mail client than a form <textarea> (especially when the I accidently hit "back" and the form decides to clear itself)!
For most unix/bsd/linux systems, most languages provide a programmatic wrapper around the Mail command.
If you are using the ASP.NET 2.0, you can use the System.Net.Mail namespace.
More information here
todays languages for web development usually have libraries for sending e-mail. it depends which language you use, but you'd find it in your language's docs. it's pretty simple, the library inside your language usually encapsulates and provides 'smtp client' behavior which you use. you provide mail message with sender and recipient, and the data for connecting to your SMTP server.
or, you sometimes may use the SMTP capabilities on the machine where your web server is, if those are available. i'm not sure whether it gets worse for the e-mail at the recipient server because your server might not be recognized as mail server for the domain... someone with more experience might comment on that.
Well, here's what not to do:
Please spam me, kthx
It is a better code pattern to have users submit a form, sanitize the input and format it however you see fit, and then pass the data to a mail function in your language of choice.
Sending mail should be done server-side - the specifics change according to your server-side language, your operating system, and what access your server has to an SMTP server.
If you're looking for a lightweight way to add a contact form to a blog or public website, try Wufoo - you can add a contact form that will send you email very easily (up to 3 forms for free). I am not affiliated with them, I just think they're cool.
