# Subscribers getting "incorrect" error messages

 * I searched the forum, and I do see a few mentions of an issue that is similar
   to this one, but I dont’ think the same.
 * If someone subscribes as [Joe@mail.com](https://wordpress.org/support/topic/subscribers-getting-incorrect-error-messages/Joe@mail.com?output_format=md)
   and then later on tries to unsubscribe as [joe@mail.com](https://wordpress.org/support/topic/subscribers-getting-incorrect-error-messages/joe@mail.com?output_format=md)(
   with a small j instead of a capital J), he will get an error message that tells
   him the address is not on the mailing list.
 * I’m not sure about Internet standards, etc, but if we focus on the subscriber,
   this error message behavior is a ‘mistake’. To him/her, [Joe@mail.com](https://wordpress.org/support/topic/subscribers-getting-incorrect-error-messages/Joe@mail.com?output_format=md)
   = [joe@mail.com](https://wordpress.org/support/topic/subscribers-getting-incorrect-error-messages/joe@mail.com?output_format=md).
 * When the next release of subscribe2 comes out, it would be nice to see this issue
   addressed.
 * Thanks!

 * There is nothing to ‘address’, Subscribe2 complies with internet standards here.
   
   [http://www.ietf.org/rfc/rfc5321.txt](http://www.ietf.org/rfc/rfc5321.txt)
 * Focussing on the subscriber should not simply disregard these standards which
   specify that [Joe@mail.com](https://wordpress.org/support/topic/subscribers-getting-incorrect-error-messages/Joe@mail.com?output_format=md)
   is not equal to [joe@mail.com](https://wordpress.org/support/topic/subscribers-getting-incorrect-error-messages/joe@mail.com?output_format=md).
   It may well be a fringe case but what you propose may well end up with conflicts
   and one user being able to unsubscribe a different subscriber.
