The discussion revolves around the case sensitivity of email addresses in the incoming email feature for posting topics. paully21 notes that users often use mixed-case email addresses (e.g., TomSmith@email.com), which can cause issues because the system currently requires an exact match. mcwumbly points out that case sensitivity has caused problems in other areas, referencing related discussions. downey asks if the validation can be made case-insensitive. codinghorror confirms that @neil will address the issue. sam adds that a database-level fix is also desired. neil confirms that email case sensitivity has been removed, resolving the issue.
Because their Discourse profile has the e-mail address as 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?
