std.net.isemailValidates an email address according to RFCs 5321, 5322 and others. Authors:
Boost Software License 1.0 Version:
3.0.13 - Version 3.0 of the original PHP implementation: http://www.dominicsayers.com/isemail Standards:
- RFC 5321
- RFC 5322
- Check that an email address conforms to RFCs 5321, 5322 and others.
As of Version 3.0, we are now distinguishing clearly between a Mailbox as defined
by RFC 5321 and an addr-spec as defined by RFC 5322. Depending on the context,
either can be regarded as a valid email address. The RFC 5321 Mailbox specification
is more restrictive (comments, white space and obsolete forms are not allowed).
The DNS check is currently not implemented. Parameters:
an EmailStatus, indicating the status of the email address.
- Enum for indicating if the isEmail function should perform a DNS check or not.
- Does not perform DNS checking
- Performs DNS checking
- This struct represents the status of an email address
- Indicates if the email address is valid or not.
- The local part of the email address, that is, the part before the @ sign.
- The domain part of the email address, that is, the part after the @ sign.
- The email status code
- Returns a describing string of the status code
- Returns a textual representation of the email status
- Returns a describing string of the given status code
- An email status code, indicating if an email address is valid or not.
If it is invalid it also indicates why.
- Address is valid
- Address is valid but a DNS check was not successful
- Address is valid for SMTP but has unusual elements
- Address is valid within the message but cannot be used unmodified for the envelope
- Address contains deprecated elements but may still be valid in restricted contexts
- The address is only valid according to the broad definition of RFC 5322. It is otherwise invalid
- All finer grained error checking is turned on. Address containing errors or warnings is considered invalid. A specific email status code will be returned indicating the error/warning of the address.
- Address is either considered valid or not, no finer grained error checking is performed. Returned email status code will be either Error or Valid.
- Address containing warnings is considered valid, that is, any status code below 16 is considered valid.
