I'm writing a script to do email filtering, and I have some questions:
1.> These are all valid email address:
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED] <- this is valid, but not standard
The problem is that last one with DOMAIN.CC format. Not having a TLD is NOT
TYPICAL for UK domains (there are only 7?), but are there other non-US
countries using a similar format? This is what I am expecting for
international emails, and others will presently fail:
USER_NAME[_W_DOTS*]@CNAMES*.DOMAIN.TLD.CC[:PORT?], an extreme being like
this:
[EMAIL PROTECTED]:8021, where 'TLD' is required
if 'CC' is present.
Is this a problem?
2.> Do email addresses ever have port numbers appended, like this:
[EMAIL PROTECTED]:24
?
3.> Are there any US domains that don't look like this:
CNAMES*.DOMAIN.TLD[:PORT?]
Let me know,
Grant M.
