I am receiving this error every time I try to send a message. The size of the message you are trying to send exceeds a temporary size limit of the server. The message was not sent; try to reduce the message size or wait some time and try again. The server responded: 4.7.1 <[email protected]>: Recipient address rejected: [email protected] exceeded daily recipients threshold . See http://postmaster.frontiernet.net. This happened randomly and without provocation. I have talked to my mail provider and they are telling me that it is an internal error. They have checked my connection settings and everything is set up properly. The messages i am sending are just test messages with one word in them.
