Email Validation RegEx fails for TLD >9 chars

Running MojoPortal 2600 / MSSql (more details available, but not necessary to reproduce the problem).

Trying to add a new user with the email address xxx@yyy.zzz fails, if "zzz" has more than 9 characters.

The current TLD is ".university" which has 10 characters. The system will accept any (non existant) domain if I drop any character from the word so it fits the 9-character-boundary.

From what I understood, this is due to a client-side RegEx (EmailValidator), but how can I fix this?

Re: Email Validation RegEx fails for TLD >9 chars

Hi,

You can add the following to your user.config file. After changing the user.config, you will have to "touch" the web.config to get IIS to reload both files.

By default, the 10 at the end of the value string is a 9. Increasing it to 10 should allow for TLDs of up to 10 characters. I caution you on increasing it more than you really need to because it can lead to performance issues.

<add key="CustomEmailRegex" value="^([0-9a-zA-Z](['-.\w]*[_0-9a-zA-Z])*@(([0-9a-zA-Z])+([-\w']*[0-9a-zA-Z])*\.)+[a-zA-Z]{2,10})$" />

Thank you,
Joe
