We have turned on the feature to allow our users to start a new topic using the incoming e-mail feature.
I notice that many of our users set up their e-mail clients to have upper and lower case letters in their e-mail addresses.
For example, [TomSmith@email.com](mailto:TomSmith@email.com)
Because their Discourse profile has the e-mail address as [tomsmith@email.com](mailto:tomsmith@email.com) the e-mail is rejected because it does not match the list of valid user e-mail addresses.
Is it possible to have the validation for incoming topics by e-mail be a case-insensitive match of existing e-mail addresses?

There are some other places where email case sensitivity has caused issues.

I would consider this a bug, as the effect is that people aren’t able to post via e-mail when they otherwise should be able to do so.

Yes, @neil will remove case sensitivity in emails before V1.0

@neil we also want to fix this at the db level. Make email unique, always downcase emails you store.

Email case sensitivity is removed! It solves this problem with reply-by-email and creating topics by email, among others.
