Package Exports
- smtp-address-parser
- smtp-address-parser/dist/lib/index.js
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (smtp-address-parser) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
smtp-address-parser
Parse an SMTP (RFC-5321) address.
Some notes
** Changes in version 1.1.0: **
** Domains are now checked beyond RFC-5321 syntax only **
Domain names must be fully qualified; that is with at least two labels. The top-level domain must have at least two octets.
** Length limitations are now checked **
Total length limit of an address is 986 octets; based on a 1,000 octet SMTP line length.
See https://tools.ietf.org/html/rfc1035 section 2.3.4. Size limits:
Domain names are limited to 255 octets, when encoded with a length byte before each label, and including the top-level zero length label. So, the effctive limit with interstitial dots is 253 octets.
Labels within a domain name are limited to 63 octets.
The above are limits of the DNS protocol, not any particular implementation.
RFC-5321 section 4.5.3.1. “Size Limits and Minimums” still says:
“To the maximum extent possible, implementation techniques that impose no limits on the length of these objects should be used.”
