GMail has an option to post in plain ASCII text. Please use it. Now, exactly what is your question? A client is trying to send you an e-mail and it is being rejected, correct? The error message clearly tells you why that is happening. In any case, without the offending IP, there is no way for anyone to check out the validity of the error message. -- Jerry ✌ postfix-u...@seibercom.net _____________________________________________________________________ TO REPORT A PROBLEM see http://www.postfix.org/DEBUG_README.html#mail TO (UN)SUBSCRIBE see http://www.postfix.org/lists.html
