	Mail transfer agent - Wikipedia, the free encyclopedia
		A mail transfer agent or MTA (also called a mail server, or a mail exchange server in the context of the Domain Name System) is a computer program or software agent which transfers electronic mail messages from one computer to another.
		It receives messages from another MTA (relaying), a mail submission agent (MSA) that itself got the mail from a mail user agent (MUA) or directly from an MUA, thus acting as an MSA itself.
		The delivery of email to a user's mailbox typically takes place via a mail delivery agent (MDA); many MTAs have basic MDA functionality built in, but a dedicated MDA like procmail can provide more sophistication.

	Mandragor & Apinc - Free Documentation Base (Site not responding. Last check: 2007-09-18)
		For mail submission and delivery of short messages EMSD is up to 5 times more efficient than SMTP both in terms of the number of packets transmitted and in terms of number of bytes transmitted.
		More than one mail submission and delivery protocols which address requirements specific to a particular user's environment are likely to be developed.
		The Submission Verify operation succeeded, meaning that the UA received the request, and responded with a message stating that it wants the message to be sent.

	Zvon - RFC 2524 [Neda's Efficient Mail Submission and Delivery (EMSD) Protocol Specification Version 1.3] - ...
		Mail in the Internet was not a well-planned enterprise, but instead arose in more of an "organic" way.
		For the purposes of this specification, mail submission is the process of putting mail into the mail transfer system (MTS).
		For the purposes of this specification, mail delivery is the process of the MTS putting mail into a user's final mail-box.

		Message Submission Agent (MSA) A process which conforms to this specification, which acts as a submission server to accept messages from MUAs, and either delivers them or acts as an SMTP client to relay them to an MTA.
		The address in MAIL FROM appears to have insufficient submission rights, or is invalid, or is not authorized with the authentication used; the address in a RCPT TO command is inconsistent with the permissions given to the user; the message data is rejected based on the submitting user.
		Enforce Submission Rights The MSA MAY issue an error response to the MAIL FROM command if the address in MAIL FROM appears to have insufficient submission rights, or is not authorized with the authentication used (if the session has been authenticated).

	Procmail disclaimer
		Mail Transfer Agent - the program which manages inter-system message delivery (and which also determines which type of delivery should be used, even for messages determined to be for local delivery).
		Mail Submission Agent - in newer versions of Sendmail, messages delivered to the mail system from the local host are queued through this process, which in turn passes them to the MTA.
		Mail Delivery Agent - often assumed to be synonymous with LDA, but actually, this may refer to one of several delivery agents, including the Program delivery and file delivery.

	Identified Internet Mail
		This MTA or MSA would typically have a private key that is authorized to send mail for anyone in the domain.
		In order to retain the current semantics and visibility of the From header, verifying mail agents SHOULD take steps to ensure that the Sender address is prominently visible to the user if it is used to verify the message and is different from the From address.
		A variation on this attack is that if a very large amount of mail were to be sent using spoofed addresses from a given domain, the key registration servers for that domain could be overwhelmed with requests.

		Mail Delivery Agent (MDA): the component of an MTA which is responsible for the final delivery of a message to a local mailbox on disk.

	rfc3888
		Originating Mail Submission Agent (MSA) The Mail Submission Agent accepts a message from a User Agent, adds or modifies it as required for Internet standards and/or site policy, and injects the message into the network.
		The MSA may be the initial MTA or may hand off the message to an MTA.
		Intermediate Message Transfer Agent (MTA) An Intermediate MTA is an MTA that accepts a message for transfer somewhere else.

	Mail Architecture
		Mailing list maintenance and bounce functionality loading is relatively light, and as a result, would most likely be the last machine to require scaling.
		The mail relays would then pass messages to a series of store/forward machines, which accept and deliver mail locally for legitimate users and forward mail on for customers who choose to retrieve their mail from some other server.
		The methodology utilized to address scaling of services as it pertains to mail storage in the past was to use the POP3 proxy functionality and forward the request to the appropriate machine by using some sort of a database updated by the provisioning process.

		I typically provide this on my mail servers via inetd/stunnel as a way to get around providers who block port 25 to stop spammers.
		The new "right" way is to use the MSA (Mail Submission Agent?) on port 587, and most modern MTA's support it out of the box.
		MSA is an attempt to separate client-to-server SMTP from server-to-server SMTP.

	Kasoft Central: SMTP is not secure
		A Mail Submission Agent (MSA) is a program running on a mail server which acts to inject new mails into the mail system arriving from MUAs.
		A Mail Transfer Agent (MTA) is a program running on a mail server which acts to relay mails to another MTA or store e-mails on behalf of local users of the system on which the MTA is running.
		Using the ESMTP submission port [RFC2554] is not sufficient, as this does not require submitters to use the port.

	RE: [draft-ietf-opes-smtp-use-cases-01]
		Please let's stick with the wording we agreed on earlier: There are two agents: OPES processor and callout server.
		In that email server an MSA (mail submission agent) is waiting for your email and uses a MTA (mail transfer agent) within the same server to forward this email to other domains.
		In the destination email server there is then a MDA (mail delivery agent) that may put the email in the recipient's mailbox.

	Internet Mail Architecture
		When not part of a mailbox address, a domain name is used in Internet mail to refer to a node that took action upon the message, such as providing the administrative scope for a message identifier, or performing transfer processing.
		When resending a message, the submission agent may record a Received header field, to indicate the transition from original posting to resubmission.
		However its discussion of the roles and responsibilities for different mail service modules, and the information they create, highlights the considerable security considerations that must be present when implementing any component of the Internet mail service.

		In other words, instead of having a single MTA that also doubles as a Mail Submission Agent (MSA), separate the functions into two services--let the MTA listen for server-to-server connections on port 25, and have the MSA listen for client submissions on port 587.
		If a lot of genuine mail is being flagged with BAYES_99, it usually means that either the database has become corrupt or that extensive learning mistakes have occurred.

		In high-traffic situations, the job of handling messages from MUAs (including parsing mail addresses, qualifying hostnames, formatting headers, etc.) is enough that for the MTA to do this in addition to actually sending the mail proves to be too much.

		The Identified Internet Mail (IIM) specification was submitted to the IETF as an Internet draft in July 2004 and is under review.

		Alternatively, a mail user agent (MUA), software used by the message writer or reader, or mail submission agent, a type of MTA that authenticates the message sender, can sign the message.
