RSET clears EHLO

[ernezt]

When issuing a RSET command, mailhog will reset the SMTPMessage. This will also clear the original Helo value. Since a "real" mail server will usually keep the smtp HELO value intact, would it be worthwhile to also have that behaviour here?

smtp/protocol.go

Line 233 in 0c4e9b7

proto.Message = &data.SMTPMessage{}

I actually have a fix for this in #4 (with one additional fix in my other PR). But I think this project is abandoned (see #5).
