Hi I am trying to install hotwayd but when I come to the smtp bit, I get this message: 'Building hotsmtpd: no You are missing cyrus-sasl v2 required by hotsmtpd to authenticate. Hotsmtpd will not be compiled unless you install this library and re-run configure.' So I download cyrus-sasl and configure, which seems to be OK but when I make I get loads of errors: 'digestmd5.c:279: warning: pointer targets in initialization differ in signedness' What am I doing wrong?
