Can someone tell me if I have covered all Email protocols when using an Email client and Web Mail to send and receive email?
Email client:
POP -Receiving an email;
IMAP -Receiving an email;
SMTP -Connecting to Mail Server (Sending an email);
SMTP Relay -Connecting directly to Mail Relay Server (Sending an email);
Web Mail
HTTP -Receiving / Reading emails;
SMTP -Sending an email
Many Thanks,
Thanks Max what would be a better label that would include SMTP Relay and HTTP with IMAP, POP and SMTP - interfaces perhaps? – nav – 2013-07-19T09:18:24.380
REad http://tools.ietf.org/html/rfc821 and you will see that there is no SMTP Relay protocol it's just part of the SMTP protocol. You could try to include HTTP with the others by asking for the Application layer protocols in the sending and receiving of emails via a desktop and a web client, but that would still at least include DNS
