I answered a question privately about bounces ... but I thought maybe the list members could benefit from the explanation: When the lists used to use SmartList software to manage the lists we would receive EVERY BOUNCE and count each one until the threshold was reached and the address would be unsubbed (often in as little time as one day)...under MailMan that is no longer true. If a subscriber's address starts bouncing MailMan keeps track of the bounces and counts for 5 days of bounces (doesn't matter how many bounces come through in a day--only one per day counts). After 5 days (unless you change your tools settings for bounces) the address is unsubbed and you get a copy of the FINAL bounce and unsub notice. Actually MailMan just suspends the account but RootsWeb list techies set things up so that the address is then UNSUBBED from the list. MailMan also differentiates between HARD bounces and SOFT bounces and counts them differently...HARD bounces are the ones that say the address is no longer valid (meaning it isn't likely to EVER be again) and SOFT bounces are the ones that say can't deliver at this time -- which may indicate a temporary issue that will be resolved and all will be well later on. Also unlike SmartList which only counted a single subscriber bounce at a time and after that address was removed started counting another bouncer in the batch -- one at a time until each in a row got unsubbed--MailMan counts EVERY bouncer in a batch of list mail so you can see a bunch of bad addresses all being removed at one time on a list that has seen little or no activity and suddenly comes to life.
