Having enabled shared mailboxes - is there a way to provide access to all users' mailboxes by a given user? Instead of having to manually provide ACL rights to every mailbox of every user? -- Daniel

And I'won't give up one of my most effective Anti-Spam measures, because an ISP ist slow in adding a reverse DNS. Yes, there is as risk of false positives, if you try to block spam (though in this case, it is no false positive at all), but what is the alternative? Stop blocking Spam? I don't think so.

Regardless of how efficient you spam filters are, if they produce false positives, then they're not usable at all. If you disagree, then nere is a 100% guaranteed way to stop ALL your spam: /etc/init.d/postfix stop Regards, Giles

Yes I know some ISP dont care and shrug their shoulders, I tell the people who complain to postmaster address to find an ISP who can set up their networks and cares about their users! My employer does not pay me to sit here and update the whitelist files every 15 minutes because of some ISP who doesn't care about their users sending mail, and at my last employer a couple of years ago, we did the sums, 92% of spam stopped by rejecting no dns hosts! even here I still see it mx-in1 ~$ cat maillog | grep -c "cannot find your hostname" 5328 mx-in2 ~$ cat maillog | grep -c "cannot find your hostname" 7041 in only 20 hours since logs rolled!!! enjoy your spam :->

[Dovecot] Unknown setting: dbox_attachment_dir
Hi, I am trying to set up Dovecot with sdbox and sis (single instance
storage of attachments), however I get the following error when attempting
to start dovecot:

I'd appreciate help on getting this up and running. This is a virtual (for
the time being) server, running Centos, and Dovecot 2.
