I set up a Gmail account for sending via Method, but it requires PORT 465 for SSL. Can I set up method to send via that port when I put in the information?
Currently SSL setup is not supported in Method. You can use your own SMTP Server or you can sign up for SMTP2GO by visiting http://www.smtp2go.com/ for a nominal fee of $2 per month.
Just to give you a heads up, supporting SSL in Method is something that we would like to accomplish in the near future. It is already on our list for future updates. It will be posted on our blogs once it becomes available.
