[Mtools] Mtools mailing list address change

[Alain Knaff]

Due to some hard disk issue at tux.org, and also for simplification 
purposes, the address of the mtools mailing list has been changed.

The new list address is now:    address@hidden
The archives URL is:            http://mtools.linux.lu/pipermail/mtools/

The subscriber list has already been imported into the new host, so no 
specific action is needed on your part in order to keep your subscription.

You only need to remember to use the new address 
(address@hidden) when posting to the list.

Sorry for the inconvenience,

Alain
