Hey Group,

So I have had limited success actually sending an email using the SETUPEMAIL / EMAIL commands.
I am able to send one using "smtp2go" but I have not been able to get my local ISP's email to work.

What type of encoding (if any) is used inside the ESPBASIC email commands?? Base64??

Is it using any encryption?? SSL vs TLS vs STARTTLS ??

the response I get back (in the serial monitor window) from my local ISP looks like this...

What kinds of success / failure have others had??

There is no encryption at all.

It just uses base 64

I have no problems in connect to my company's mail server. A standard server running apache, php, etc. Works every time.
