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
Because their Discourse profile has the e-mail address as firstname.lastname@example.org 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?
