Hello guys.. In my setup im using MailDir format (centos5, postfix, dovecot), then my goal is to setup mailbox size limit, but sad to say MailDir is not capable to handle my requirement (i dont know if this is true), now i found an article saying that MailDir++ can support mailbox limit... my problem is how can i "convert?" maildir to maildir++ format? Please help me .... linux beginner here..... thanks alot.
If by limiting size you mean setting quota's them dovecot can do that with the normal maildir format, there are several drivers to configure that. Information on that is found here http://wiki.dovecot.org/Quota
