I have found it the hard way. This is not specific to Python. It’s a general limitation of the inotify interface, and is necessary to avoid a trivial denial of service by being slow to consume events. Inotify does tell you when events have been lost, though, which allows you to resynchronize. -- Sincerely, Demi Marie Obenour (she/her/hers) OpenPGP_0xB288B55FFF9C22C1.asc Description: OpenPGP public key OpenPGP_signature Description: OpenPGP digital signature
SASL authentication question
I have configured Postfix with Cyrus-sasl to send mail with Active Directory authentication. I'm very happy with the result, my users log in with a firstname.lastname user and their Windows password. But I have a router that needs to send mails and that has only one field that is used for both the login and the sender's email address. So here is my question, I am looking for a server equivalent to this client option smtp_sasl_password_maps, to add in a file the adapted login. Do you have an idea? Samuel
Muliple mail delivery
Dear Folks, Is there any easy way to get a single instance of postfix running on a single server to deliver a piece of mail to a two different but identical mailboxes on the same server. For example to home/user/Maildir and home2/user/Maildir on a different partitiion? Want a redundant copy of all incoming mail in case drive fails. Raid is too dangerous, if FAT gets corrupted it destroys all disks in the raid. Presently I got 3 drives rsyncing from the mail drive repeatedly through out the day. It works... Thanks for tolerating my stupidity.

Aliases can take a comma-separated list of file locations, in addition to pipes, usernames, and the like. That solves what you are asking for. How would you propose to handle syncing the state of which messages have been marked read, etc? -Dan

How would you propose to handle syncing the state of which messages have been marked read, etc? NO idea, the idea thought is simply to have a continuity of mail coming in. The rsync idea may still be useful. Thanks Homer -Dan
