 Hi @asaifm and welcome to Trac!

 Updating this to use lower-case comparisons (Just throw it through
 strtolower() IMHO) seems reasonable, however.. a plugin altering the user
 email address to lower case does seem unexpected and potentially a bigger
 bug than this is.

 Just as a note, `user at example.com` and `USER at example.com` could
 ''technically'' be different users, as the email standard delegates that
 to the mail servers, however in reality no mail servers that I'm aware of
 have case sensitive handling..
