Package Exports

server-accepts-email

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 (server-accepts-email) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Other libraries

There are some other libraries that does the same thing, but I found them to have some flaws which made me write this one.

	Promise API	Follows RFC5321 ¹	Proper Errors ²
`server-accepts-email`	✅	✅	✅
`email-exists`	✅	❌	❌
`email-existence`	❌	❌	❌
`email-verify`	❌	❌	✅

¹ None of the other libraies parsed the replies to support multiline replies, but instead relied on every reply comming in a chunk, accepting all data and searching for substrings, or something similar.

² Some of the other libraries rejects, or calls callback, with something other than an Error instance.
