Hi, no im not using any black listing. I am also using spamassasin but no black list there either.
I am no expert at postfix but looks like after the connection is made the negotiation fails, is there any commands to make postfix more friendly to other protocols maybye?
I noticed it happens more on emails with attachements, could it be the mtu? I am on adsl 2 with maximum 1492. I used to have trouble uploading files to the FTP that I am also running from outside the network but recently this problem went away. I am really lost here
