According to [1], Trash is a reserverd folder name. When moving a message to it, maildirsize should be update with a negative byte count.

Well, yea.. I'm ignoring that part of the Maildir++ spec. Perhaps it could be done optionally, but I'm not sure if it's still that good of an idea.

I think a better idea is to give Trash mailbox a bit of extra quota, instead of unlimited quota. Unfortunately this won't work with v1.0's quota plugin, but it is possible with my rewritten quota plugin:

http://dovecot.org/patches/1.0/quota-rewrite.diff

Quota plugin. Multiple backends are supported:

dirsize: Find and sum all the files found from mail directory

dict: Keep quota stored in dictionary (eg. SQL)

maildir: Maildir++ quota

fs: Read-only support for filesystem quota

Quota limits are set using "quota_rule" parameters, either in here or in

userdb. It's also possible to give mailbox-specific limits, for example:

quota_rule = *:storage=1048576

quota_rule2 = Trash:storage=102400

User has now 1GB quota, but when saving to Trash mailbox the user gets

additional 100MB.

Multiple quota roots are also possible, for example:

quota = dict:user::/etc/dovecot-user-quota.conf

quota2 = dict:domain:%d:/etc/dovecot-domain-quota.conf

quota_rule = *:storage=102400

quota2_rule = *:storage=1048576

Gives each user their own 100MB quota and one shared 1GB quota within

the domain.

#quota = maildir
