Hello there,

Here's my two pennies of wisdom:

If you want to use typolight smtp feature with gmail you must:

1. Use exactly!!! ssl://smtp.gmail.com as smtp server
2. Use port 465
3. Use full email as username e.g. username@gmail.com

I tried it with TL 2.6.1 and it works!

Beware of the limitations google enforce for the number of outgoing mails per day when you send newsletters

Google has a number of sending limits in place to prevent abuse of our system, and to help fight spam. If one of your mail accounts reaches an abuse limit, the account will be temporarily unable to send mail.

Each Standard Edition account can currently send to 500 external recipients per day. Premier and Education Edition users can send to 2000 external recipients per day. The email addresses can be distributed among the To:, Cc:, and Bcc: fields.
