In dovecot, what syntax to use if I have a space in mysql password?

I'm trying to configure Dovecot to access mysql, but it's not working because there is a space in the mysql password. driver = mysql connect = "host=localhost dbname=postfix user=postfix password=blah bluh blih" When I'm trying to access a mailbox from Thunderbird / Evoution, I'm getting this error : Jan 05 14:41:11 mx1 dovecot: auth: Fatal: mysql: Missing value in connect string: bluh I can't find the proper syntax to make it work. Has someone an idea ?
