Hummm.. the plot thickens.....
According to strace sieveshell is happily opening several of the files in
/usr/lib/sasl2/ as read only. So.....
I'm guessing that sieveshell isn't finding the plugin it wants? I'm trying
to use pam_mysql with sieve like I use with imapd but imapd appears to be
happy.... If it would help I can send the strace output....
