Feature: #93668 - Possibility to configure Symfony mailer

See forge#93668


The install tool has now the possibility to configure the Symfony mailer with DSN. 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 documentation.

In the module Admin tools > Settings go to the card Configure Installation-Wide Options and open the dialog. Select Mail and set [MAIL][transport] to dsn.

Additionally set [MAIL][dsn] like described in the Symfony documentation.


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


If [MAIL][transport] is set to dsn all mails are sent with your configured DSN.
