Hi,

I dont know why dsync requires o+rx in working dir, at least it could give 
better error message when working dir has o-rwx.

# cd
# mkdir test
# cd test
# dsync -D -v -u 'info at example.org' -o 'mail_privileged_group=mail' -o 
'mail_location=mbox:/email/info at example.org/mail:INBOX=/var/mail/info at example.org' 
mirror 'maildir:~/Maildir'
dsync(info at example.org): Info: Sport: only in source
dsync(info at example.org): Info: INBOX: only in source

# cd
# mkdir test
# chmod o-rwx test
# cd test
# dsync -D -v -u 'info at example.org' -o 'mail_privileged_group=mail' -o 
'mail_location=mbox:/email/info at example.org/mail:INBOX=/var/mail/info at example.org' 
mirror 'maildir:~/Maildir'
