Hi, I recently started having delivery problems with list messages to Hotmail subscribers. The problem seems to have started on or around June 10. I checked the syslog file and was seeing occasional (452 too many recipients for delivery) errors. I changed SMTP_MAX_RCPTS to 5 and SMTP_MAX_SESSIONS_PER_CONNECTION to 5 as well. That seems to have cleared up the '452' errors. All messages handed off to Hotmail users in the last 24 hours or so have (250 <[EMAIL PROTECTED]> Queued mail for delivery) successful return codes (as far as I see). Yet, none of the list subscribers are receiving messages. If I send a test message to some of the subscribers directly (not via Mailman), they get it.
Beyond telling people to dump Hotmail, does anyone have any "best practices" they can share for getting Mailman messages delivered to Hotmail subscribers successfully? I have already read FAQ 3.42 on the new FAQ wiki (thanks, Barry and Co). And, I have already read - http://postmaster.live.com/Guidelines.aspx , and my co-admin and I are looking into implementing SenderId/SPF keys for the domain DNS records. Any other advice for Hotmail?
