True if user input mobile phone or email

My RFC 5322 implementation for email validation with few limitation on top level domain name

because everything else is too strict

Email clients insert the "sender wrote" line to email replies.

Verify an email is OK

Validates most email addresses. Using the range [A-Za-z0-9] at the beginning instead of \w means an address cannot begin with an underscore. This range is also used to exclude underscores from the domain (part after @).

Supports new top level domains, such as .plumbers .blackfriday

get ip identifier, queue name, email domain and status from postfix log

Groups for: Whole email user domain Matches valid emails with numbers, chars, dots and dashes, domains with extensions of 2 or 3 letters.

Very simple & basic. More forgiving, less stringent. Allows anything which looks reasonably valid. Allows one at-symbol. Requires a two part hostname (i.e. abc@localhost is not allowed)

Recherche un email

Matches email with groups for username and domain.
