13 Jul 15 Sympa List Management Software Upgrade

We are experiencing blocking of outbound email from Sympa because of inadvertent passage of actual spam. The upgrade to Sympa includes enhancements for managing email which should reduce the possibility of Spam.  After implementation, we must request review by our Spam detection provider to remove the outbound block.

We have 72,533 unique users that are members of active lists (with the majority being members of more than one list) and 88 gigabytes of archives. Sympa processes approximately 100 emails per minute.

We are using this upgrade to bring our list processing practices in line with current best practices. Passwords for the web interface must be reset – after the upgrade users must perform password recovery.  We will validate list subscribers.  The method has yet to be determined.  We are developing a communication about these changes.

We estimate it will take today and tomorrow to perform the upgrade and hope to have everything back online by EOB on Wednesday or Thursday at the latest.
