Subject: [exim] Supported password hash schemes
Hello,

What password hash schemes does Exim 4.82 on Ubuntu 14.04 support? I
found the crypteq string expansion [1] that only mentions md5 and sha1
schemes and an unspecified platform-handoff (crypt). crypt16 is probably
irrelevant. Also, it mentions optional {...} prefixes but not the common
$1$, $6$ etc. prefixes. Are they alone also recognised?

How can I crypt passwords for exim to understand them? I'm looking for
the most secure method, preferably one out of bcrypt or sha512crypt.
