Is it OK to autocorrect users when they have mistyped parts of their email address?

When logging in, users might mistype parts of their email address. For example, name@company.con instead of .com, Yaho instead of yahoo, etc.

The main rationale is that by autocorrecting user input we could avoid unnecessary error messages that are either due to misspellings or other common typing errors.

So my question or rather questions are:

1. Is there a list of common typo errors associated with typing an email address?


2. Are there any access security implications?

Answer

I would recommend against an auto-correct as domain name extensions are about to change drastically, to the point where an email ending with "sitename.anything" will be valid.

Consider an inline check, which means it doesn't cause the frustration of the usual ENTRY > SUBMIT > ERROR MESSAGE > RE-ENTRY > SUBMIT

name@company.co
[!] Did you mean .com?

Asking for a quick confirmation before submission saves time for both the user and the system.
