We have this issue with 4 clients at the moment.

If they get sent an external email from an email address that has a dot (.) before the @ symbol, only the first part of the email address is used when trying to reply.


Client gets an e-mail from anon.ymous@xyz.com

Client hits reply and types an e-mail then hits send. They subsequently get a bounceback saying:

anon@xyz.com does not exist.

This only happens on iPhone's and does not happen on all iPhones.

Any help appreciated.
