I am looking for a way or tools to reduce identity theft on my Cyrus
imap server.
For example , scripts to geo localise ip requests , detect and reject
bad connexions ?
Is it possible to authorize few devices for a user and reject other
devices ?
Which tools do you use on your Cyrus imap servers to protect them ?
fail2ban and fail2ban-repeater

ipset-blacklist https://github.com/trick77/ipset-blacklist (great for
banning whole countries)
password policies
Plus the usual: SPF, clam, spamassassin, greylisting, etc
Spam check outgoing mail too.
