This thread was helpful for me, too, since I'm trying to make sure our Postfix settings are compliant with Yahoo!'s guidelines. Their Postmaster site says: "Yahoo! Mail accepts a maximum of 20 messages per SMTP connection. We encourage you to cap the number of messages you send to Yahoo! Mail to fall within this per-connection limit. When this limit is reached, no further messages will be accepted for delivery as our server automatically terminates the connection (without giving an error code). If you are sending messages to a significant number of Yahoo! Mail users, the suggestions below will help ensure uninterrupted delivery for your messages." So, since the default_destination_concurrency_limit = 20 on my system, do I not need to worry about setting up a custom transport for Yahoo!? Or have others on this list found that creating a transport for Yahoo! with additional custom settings has been helpful when delivering to them with Postfix? Thanks, SteveJ
