Send Mail with Mailtrap and Cloud9 IDE


#1

Hi
I would like to send a test mail via Mailtrap.
Unfortunately, I always get an error message, although I have adopted the configuration as in mailtrapp. io.
The mistake is:
PHP Warning: stream_socket_client(): unable to connect to smtp.mailtrap.io:465 (Connection timed out) in /home/ubuntu/workspace/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/StreamBuffer.php on line 267
Swift_TransportException with message 'Connection could not be established with host smtp.mailtrap.io [Connection timed out #110]

My settings in the. env are:
MAIL_DRIVER=smtp
MAIL_HOST=smtp.mailtrap.io
MAIL_PORT=25
MAIL_USERNAME=unpublished
MAIL_PASSWORD=unpublished
MAIL_ENCRYPTION=

Is this possible with C9 or is there something blocked?
Thanks for your help
