I have a question about SMTP support with the Microchip PIC32. We had a complete application ready to go with HTTP, SNMP and SMTP services and a custom bootloader but now many email servers are requiring TLS support which the Microchip MLA libraries do not have as far as I know.

I understand that wolfSSL has TLS support but it's unclear how we would use it for SMTP with our current application based on the Microchip MLA.

Can we add wolfSSL to our current application and get SMTP working with TLS or must we upgrade to Microchip Harmony which, I believe, has support for wolfSSL and, I assume, SMTP with TLS.

Help!
