Describe the bug The email address field for used for login is case sensitive.

Nginx Proxy Manager Version v2.9.15

To Reproduce Steps to reproduce the behavior:

1. Create an account with a capital letter in the user's email address, e.g. [email protected]
2. Try to log in with the email address all in lower case e.g. [email protected]
3. Login will be denied, No relevant user found

Expected behavior While email addresses are technically case sensitive (RFC 5321), providers do not usually enforce this. I believe the login handler should convert the input to lower case before comparing against the value stored in the database to

Operating System Raspberry Pi / Raspibian Buster Docker 20.10.5+dfsg1, build 55c4c88

It really depends though.. Most modern email software actually DO implement case-sensitivity in a way. As they're RFC-compliant, they must. The way they get around it is: Make your own email addresses case-insensitive and lower-cased. Incoming mail will then get turned from [email protected] => [email protected]. Treat outgoing mail as case-sensitive (send a mail with [email protected] and it'll be sent as just that).

I want to +1 this issue

Because this relates to the email login and not actually sending or receiving emails. Would this be able to be a configuration option to let the username check turn case-insensitive, even if it is changed after setup the stored emails should retain their case-sensitivity and have no effect on any other functionality or existing functionality if the default is set to how it acts now..

Man so many issues closed from stale bots... I still want this (if it has already been implemented in a newer version I would also like to know about it)
