*** GMail and Validation-Mails *** There seems to be an issue that Gmail is not accepting mails from my server. The reason is that I am currently rebuilding my server infrastructure and the MX-entries are not correctly set. I have activated the accounts using a Gmail-address manually. If you do not receive the validation mail, drop me a note to k.e.klingner@gmail.com.
