I use one IMAP accounts for an group of users which direct the interface with customers (something like office@[fqdn])
and I want to use vacation to auto reply to customers starting every working day at 20 00 and cut off this at 7 am
I tried to found any comment about a script to solve this from console but I wasn't able to find any posts or anything in manuals
if I'll find one in console to put it in chrontab it's a joke
any hint is welcomed
