Email address / addpop / What is a valid username?

[kamm]

When using addpop what constitutes a valid username ([email protected])

Minimum, maximum characters?
Characters allowed?

Is this documented anywhere?

Thanks, but that doesn't have the information I'm seeking.

I'm trying to find out what cpanel considers a valid username for an email address.

Minimum, maximum characters?
Characters allowed?
and something I just remembered...
Reserved words?

I'm not aware of any restrictions on the username part of the email account.

OK - thanks.

I think I'll just limit it to this:

/^[a-zA-Z0-9\.]+$/

...should be good enough for most purposes and no doubt addpop will fail if it's not.

OK - thanks.

I think I'll just limit it to this:

/^[a-zA-Z0-9\.]+$/

...should be good enough for most purposes and no doubt addpop will fail if it's not.

Actually, I found out that the following expression specifically gives the needed validation:

/^(?!.*(\.)\1)[a-zA-Z0-9_\-]+([a-zA-Z0-9_\.\-]+[a-zA-Z0-9_\-])?$/
