This is a list of Simple Mail Transfer Protocol (SMTP) response status codes. Status codes are issued by a server in response to a client's request made to the server. Unless otherwise stated, all status codes described here is part of the current SMTP standard, RFC 5321. The message phrases shown are typical, but any human-readable alternative ...
It is a way to secure SMTP at the transport layer, by wrapping SMTP inside Transport Layer Security (TLS). Conceptually, it is similar to how HTTPS wraps HTTP inside TLS. This means that the client and server speak normal SMTP at the application layer, but the connection is secured by SSL or TLS. This happens when the TCP connection is ...
SMTP proxies are specialized mail servers that, similar to other types of proxy servers, pass simple mail transfer protocol (SMTP) sessions through to other SMTP servers without using the store-and-forward approach of a mail transfer agent (MTA). When an SMTP proxy accepts a connection, it initiates another SMTP session to a destination SMTP ...
To allow the server to send external emails, an MTA such as Sendmail, Postfix, or Exim is required. Mail is read either through direct access ( shell login) or mailbox protocols like POP and IMAP . Unix-based MTA software largely acts to enhance or replace the respective system's native MTA.

Fully capable SMTP servers maintain queues of messages for retrying ...
