[sqwebmail] Cache create failure / s_connect() failed: Permission denied

[Brendan Pratt]

After using sqwebmail for a few months, all of a sudden it  has stopped 
working, giving errors like :
sqwebmail: authdaemon: s_connect() failed: Permission denied
sqwebmail: maildircache: Cache create failure - cannot change to bin
in my /var/log/syslog

I've been doing some research and it seems its a permissions issue I reset 
the permissions: chown bin:bin /var/run/sqwebmail
and still get the same error.

Even after checking/resetting the permissions on every sqwebmail directory 
I could find and the same errors.

It was working fine up until last night, now it just doesn't want to play ball.
