Julien's questions

Using Postfix and custom transports I can manage delivery speeds depending on the recipient's domain. (For example, I send max one message per second to *@hotmail.com)

I also use similar rules to block bad destinations (htmail.com is blocked right away, avoiding many loops in the queue).

However, I'd like to temporarily suspend mail delivery to a destination for 24 or 48 hours (mails to *@gmail.com suspended, everything else delivered). Messages would queue up during this time, and would be delivered only when I want by changing the config.

Does anyone know how to do that ?

Thanks

I recently switched from Apache 2.2 prefork to Apache 2.2 worker, but I have no idea what would be a great MPM config to start with. On prefork, I used :
MaxClients 256
StartServers 190
MinSpareServers 160
MaxSpareServers 220

I'd like to be able to accept at least as much simultaneous requests (190)

Thanks !

PS: Server environment: Debian 5.0, 2x 3.00 Ghz, 4 GB RAM, dedicated to Apache.

Do I need to stop or limit services (Apache, MySQL, ...) during software RAID 1 reconstruction on Linux ?
Is there a risk of corrupting or losing data ?

I am using Linux MD devices (with mdadm) on Debian 5.

Thanks
