Fully functional email address

[S Moonesamy <[e-mail]>]

Dear Security Area Directors,

I saw an email exchange about a complaint on the Transport Layer 
Security mailing list.  There was a request to "use a fully 
functional email address".

One of the problems which became less infrequent over the years is 
email delivery issues when I reply to some participants by email.  I 
don't know whether those participants are aware that it was not 
possible to have an email reply delivered to them because their mail 
server rejected the email (reply).  I find it easier to copy a 
mailing list instead of getting in a discussion of whether the 
sender's or receiver's email address is fully functional or not.

Regards,
S. Moonesamy
