email
Use this tag for questions involving code to send or receive email messages. Posting to ask why the emails you send are marked as spam is off-topic for Stack Overflow. Questions about configuration of mail servers belong on Server Fault.

Electronic mail, commonly called email or e-mail, is a method of exchanging digital messages from a sender to one or more recipients.

Modern email operates across the Internet or other computer networks. Some early email systems required that the sender and the recipient both be online at the same time - a system currently known as Instant messaging. Today's email systems are based on a store-and-forward model. Email servers accept, forward, deliver and store messages. Neither the users nor their computers are required to be online simultaneously; they need connect only briefly, typically to an email server, for as long as it takes to send or receive messages.

Email architecture is rich and varied; you should probably indicate whether your question concerns email-address manipulation, email composition (rfc822, mime, email-headers, html-email, etc.), message submission and transport (smtp, x400), or a particular mailbox storage and access protocol (pop3, imap) or perhaps a particular email-client. There is a large number of additional tags you can use.

Programmers coming from modern protocols such as JSON and HTTP will be surprised to learn about the many layers of standards that they have to work with in order to be able to use 8-bit data, multimedia, Unicode, internationalization, tagged content, etc. The MIME standards in particular should be at least vaguely familiar.
