These are a bad idea.
it sounds so, but in real life i cant do it with dovecot pigenhole since it skips reporting if precedence header is found :)
They are often implemented in a bad way and spam mailing lists, and debates with multiple recipients. You've probably seen it. Five people are talking, one goes on vacation, and now every every time the remaining four add something to the debate using "reply all", they get a "I'm on vacation" from the fifth guy.
this happends if vacation scripts dont take into account of maillists
An auto-responder must only fire when the Cc: line is empty, and there is only a single recipient on the To: line. But this then fails in some circumstances, the most obvious of which is that you send a mail To: A, and Cc: B, and both A and B have gone on vacation, yet their auto-responders do nothing since each one sees that there are multiple recipients.
cc empty ?
to contains rcu now
unsafe world :-)
A vacation responder must be aware of all the threads in your inbox so that it can distinguish a new discussion that you are being pulled into, from an existing discussion, and it should track everyone to whom it has sent the vacation notice so it is never sent twice to anyone (for the same vacation event).
search for precedence haeder if found do not tell vacation
Another problem is that an auto-responder will likely reply to spam no matter how carefully crafted it is.
this why some tell there vacation scrips there known sender lists imho
but it could be unsafe if spf or dkim does not pass
It is not possible for a robot to determine with perfect certainty whether an e-mail requires action or not.
+1
Basically, when you go on vacation, there are certain important business contacts who should know you're not available, and so you proactively them know, and that's it. And as far as your personal e-mail goes, unless you're backpacking through the wilderness somewhere, check the damn thing once a day while you're in vacation!
vacation single days ?
