MMDF (equals), [citation needed] RFC 5321 also warns that "a host that expects to receive mail SHOULD avoid defining mailboxes where the Local-part requires (or uses) the Quoted-string form". A local part is either a Dot-string or a Quoted-string; it cannot be a combination. The IETF's EAI Working group published RFC 6530 "Overview and Framework for Internationalized Email", which enabled non-ASCII characters to be used in both the local-parts and domain of an email address. Thus many mail servers use incorrectly other techniques and check the mailbox existence against relevant systems such as the Domain Name System for the domain or using callback verification to check if the mailbox exists. e.g., that the mail system in the domain example.com treat John.Smith as equivalent to john.smith; some mail systems even treat them as equivalent to johnsmith. Significant demand for such addresses is expected in China, Japan, Russia, and other markets that have large user bases in a non-Latin-based writing system. The maximum total length of the local-part of an email address is 64 octets.

[23][24] Postfix and Exim allow configuring an arbitrary separator from the legal character set. Another way to prevent getting this page in the future is to use Privacy Pass.

Although the standard requires the local part to be case-sensitive,[1] Conversely, a single email address may be the alias to a distribution list to many mailboxes. DataMail launches internationalized email support for 8 Indian languages using the XgenPlus email platform in India. Some companies offer services to validate an email address, often using an Application programming interface, but there is no guarantee that it will provide accurate results. Email aliases, electronic mailing lists, sub-addressing, and catch-all addresses, the latter being mailboxes that receive messages regardless of the local part, are common patterns for achieving a variety of delivery goals.

Suivre @Adresse_Ip. Interpretation of the local part of an email address is dependent on the conventions and policies implemented in the mail server. The local part of an email address has no significance for intermediate mail relay systems other than the final mailbox host. Of note for e-mail are example, invalid, example.com, example.net, and example.org. In mail systems compliant with RFC 6531 and RFC 6532 an email address may be encoded as UTF-8, both a local-part as well as a domain name. While early messaging systems used a variety of formats for addressing, today, email addresses follow a set of specific rules originally standardized by the Internet Engineering Task Force (IETF) in the 1980s, and updated by RFC 5322 and RFC 6854.
