Email error code 550
Hi, Since Jan I am unable to send Emails to @was-luzern.ch I can receive them, but every mail I try to send is returned with this error message: Email error code 550: Emails from your address have been blocked by the administrator.
I just sent same mail via Chrome with no problem!
It seems this could be a Firefox related problem, any idea?

Does the error come from your e-provider, or from the website you are sending the message to? Try contacting your e-provider support on this.
Are you possibly using a VPN or proxy ?
