BOUNCES
There are two kind of bounces:
Each GA Mailing List administrator receives corresponding Mailing List bounces.
These two kind of bounces are handled in the following way:
Please note that there is always a human being behind, and that mistakes happen.
Delivery-Reports from distant sites.
Majordomo Manual indicates clearly why Delivery-Reports from distant sites cannot be handled in automated way, and provides some tools (Perl scripts) for unsubscription /subscription of wrong e-mail addresses detected manually.
Bounced messages come in so many different formats that it's hard to completely automate subscriptions to the "bounces" list. (In fact, in some cases, the addressee of the bounced mail won't even be shown in the message!) If the list owner's system can run a Perl script, the "bounces" script makes the job easy. The script works differently than "approve". The script doesn't read a message from a file or standard input. Instead, it reads its command line arguments: % bounce listname user@xyz.com That command would unsubscribe the address user@xyz.com from the "listname" list and add them to the "bounces" list. An owner who can't run the "bounce" script can send mail to Majordomo with two commands like these: approve passwdA unsubscribe listname user@xyz.com approve passwdB subscribe bounces user@xyz.com (931005 listname) The first command unsubscribes the user from the current list. The second one subscribes the user to the "bounces" list, with a comment that shows the date and the name of the list they used to belong to.
Procedures for Delivery-Reports from distant sites to DNSO Listadmin:
Those messages which are Delivery-Reports from distant sites are considered for MANUAL search for wrong addresses.
After MANUAL scan, all wrong addresses are MANUALLY recorded in a weekly file, say weeklybounces.N, where N is a week number.
The file weeklybounces.N is compared to weeklybounces.N-1, and all addresses which are in both files will be removed from ALL GA lists using the majordomo "bounce script", described in the Manual quoted above.
An automated reminder is sent every day to e-mail addresses moved to bounces list, expecting that some of them will became valid.
