Feature #17047
Updated by c960657 (Christian Schmidt) over 4 years ago
## Proposal
In `Net::SMTP`, add support for parameters for `MAIL FROM` and `RCPT TO`, such as [SMTPUTF8](https://tools.ietf.org/html/rfc6531) and [REQUIRETLS](https://tools.ietf.org/html/rfc8689).
I suggest extending `Net::SMTP#mailfrom` and `Net::SMTP#rcpto` so they accept an additional optional Array or Hash of parameters.
For `Net::SMTP#send_message` and `Net::SMTP#open_message_stream`, I suggest that in addition to a String email address (or arrays of Strings), these methods should accept a pair (or arrays of pairs) of `[addr, params]`, where `addr` is the String email address, and `params` is an Array or Hash of parameters.
In order for the parameters to be useful, we should expose the capabilities reported by `EHLO`, so I made `capable?` public.
