'sendmail'

smtp

Sends messages over the (standardized) Simple Message Transfer Protocol. It can deal with encryption and authentication. Most flexible option, requires a mail server and configurations in transport_smtp_* settings below. Works the same on Windows, Unix and MacOS.

sendmail

Sends messages by communicating with a locally installed MTA - such as sendmail. See setting transport_sendmail_command bellow.

dsn

Sends messages with the Symfony mailer, see Symfony mailer documentation. Configure this mailer with the [MAIL][dsn] setting.

mbox

This doesnt send any mail out, but instead will write every outgoing mail to a file adhering to the RFC 4155 mbox format, which is a simple text file where the mails are concatenated. Useful for debugging the mail sending process and on development machines which cannot send mails to the outside. Configure the file to write to in the transport_mbox_file setting below

classname

Custom class which implements \Symfony\Component\Mailer\Transport\TransportInterface. The constructor receives all settings from the MAIL section to make it possible to add custom settings.

type

Default

'localhost:25'

only with transport=smtp serverport of mailserver to connect to. port defaults to "25".

type

Default

''

Some smtp-relay-servers require the domain to be set from which the sender is sending an email. By default, the EsmtpTransport from Symfony will use the current domain/IP of the host or container. This will be sufficient for most servers, but some servers require that a valid domain is passed. If this isn't done, sending emails via such servers will fail.

Setting a valid SMTP domain can be achieved by setting transport_smtp_domain in the LocalConfiguration.php. This will set the given domain to the EsmtpTransport agent and send the correct EHLO-command to the relay-server.

Configuration Example for GSuite:

return [
    //....
    'MAIL' => [
        'defaultMailFromAddress' => 'webserver@example.org',
        'defaultMailFromName' => 'SYSTEMMAIL',
        'transport' => 'smtp',
        'transport_sendmail_command' => ' -t -i ',
        'transport_smtp_domain' => 'example.org',
        'transport_smtp_encrypt' => '',
        'transport_smtp_password' => '',
        'transport_smtp_server' => 'smtp-relay.gmail.com:587',
        'transport_smtp_username' => '',
    ],
    //....
];

type

bool

Default

false

only with transport=smtp Connects to the server using SSL/TLS (disables STARTTLS which is used by default if supported by the server). Must not be enabled when connecting to port 587, as servers will use STARTTLS (inner encryption) via SMTP instead of SMTPS. It will automatically be enabled if port is 465.

type

only with transport=smtp If your SMTP server requires authentication, enter your username here.

type

type

text

Default

''

only with transport=smtp Sets the minimum number of seconds required between two messages, before the server is pinged. If the transport wants to send a message and the time since the last message exceeds the specified threshold, the transport will ping the server first (NOOP command) to check if the connection is still alive. Otherwise the message will be sent without pinging the server first.

type

Default

''

only with transport=sendmail The command to call to send a mail locally.

type

Symfony provides different mail transports like SMTP, sendmail or many 3rd party email providers like AWS SES, Gmail, MailChimp, Mailgun and more. You can find all supported providers in the Symfony mailer documentation.

Set [MAIL][dsn] to the configuration value described in the Symfony mailer documentation (see above).

Examples:

• $GLOBALS['TYPO3_CONF_VARS']['MAIL']['dsn'] = "smtp://user:pass@smtp.example.org:25"
• $GLOBALS['TYPO3_CONF_VARS']['MAIL']['dsn'] = "sendmail://default"
