Important
dot-mail is a wrapper on top of symfony mailer
Install dotkernel/dot-mail
by executing the following Composer command:
composer require dotkernel/dot-mail
If your server has Sendmail installed, update the config/autoload/mail.local.php.dist
file by setting the transport
key like below
<?php
return [
'dot_mail' => [
'default' => [
//...
'transport' => 'sendmail',
//...
]
]
]
If you want your application to send mails on e.g. registration, contact, then edit the file config/autoload/mail.local.php
. Set the transport
, message_options
and smtp_options
keys like below.
Under message_options
key:
from
- email address from whom users will receive emails
Under smtp_options
key:
host
- the mail server's hostname or IP addressport
- the mail server's portconnection_config
- fill in theusername
andpassword
keys with the login details of the email used infrom
above- if you want to disable auto_tls set
tls
key to false
Note: all other keys can be left as is.
<?php
return [
'dot_mail' => [
'default' => [
//...
'transport' => 'esmtp'
'message_options' => [
'from' => '',
//...
],
'smtp_options' => [
'host' => '',
'port' => 25,
'connection_config' => [
'username' => '',
'password' => '',
'tls' => null,
]
]
//...
]
]
]
In config/autoload/local.php
add under contact
=> message_receivers
=> to
key string values with the emails that should receive contact messages
Note: Please add at least 1 email address in order for contact message to reach someone
Also feel free to add as many cc as you want under contact
=> message_receivers
=> cc
key
Below is an example of how to use the email in the most basic way. You can add your own code to it e.g. to get the user data from a User object or from a config file, to use a template for the body.
Note that addTo
is only one of the methods available for the Message
class returned by getMessage()
. Other useful methods that were not included in the example are addCc()
, addBcc()
, addReplyTo()
.
The returned type is boolean, but if the isValid()
method is removed, the returned type becomes MailResult
which allows the use of getMessage()
for a more detailed error message. See the Testing if an e-mail message is valid
section below.
public function sendBasicMail()
{
$this->mailService->setBody('Email body');
$this->mailService->setSubject('Email subject');
$this->mailService->getMessage()->addTo('[email protected]', 'User name');
$this->mailService->getMessage()->setEncoding('utf-8');
return $this->mailService->send()->isValid();
}
It's optional, but recommended to call the above function in a try-catch
block to display helpful error messages. The next example calls the sendBasicMail
function from within UserController
, but you can implement it in other controllers, just make sure that the controller's construct also includes the FlashMessenger
parameter $messenger
.
try {
$this->userService->sendBasicMail();
$this->messenger->addSuccess('The mail was sent successfully', 'user-login');
//more code...
} catch (Exception $exception) {
$this->messenger->addError($exception->getMessage(), 'user-login');
//more code...
}
After sending an e-mail you can check if the message was valid or not.
The $this->mailService->send()->isValid()
method call will return a boolean value.
If the returned result is true
, the e-mail was valid, otherwise the e-mail was invalid.
In case your e-mail was invalid, you can check for any errors using $this->mailService->send()->getMessage()
.
Using the below logic will let you determine if a message was valid or not and log it. You can implement your own custom error logging logic.
$result = $this->mailService->send();
if (! $result->isValid()) {
//log the error
error_log($result->getMessage());
}
Invalid e-mail messages will not be sent.
Optionally, you can keep a log of each successfully sent email. This might be useful when you need to know if/when a specific email has been sent out to a recipient.
Logs are stored in the following format:
[YYYY-MM-DD HH:MM:SS]: {"subject":"Test subject","to":["Test Account <[email protected]>"],"cc":[],"bcc":[]}.
In order to enable it, make sure that your config/autoload/mail.local.php
has the below log
configuration under the dot_mail
key:
<?php
return [
'dot_mail' => [
...
'log' => [
'sent' => getcwd() . '/log/mail/sent.log'
]
]
];
To disable it, set the value of sent
to null
.
