I tested a new tb folder that starts with # with dovecot and I don't see a problem. Nothing is re-fetched on tb startup. I haven't tested on Zimbra since it is in a separate box that runs a Ubuntu LTS version that zimbra only supports (at least the free version which is what I have).

I tested a new tb folder that starts with # with dovecot and I don't see a problem. Nothing is re-fetched on tb startup. I haven't tested on Zimbra since it is in a separate box that runs a Ubuntu LTS version that zimbra only supports (at least the free version which is what I have). https://tools.ietf.org/html/rfc3501#section-5.1 discourages the use of # in names (uses "should") but doesn't forbid the use (doesn't use "shall not").

Also, where are the folders that start with # in the hierarchy? Are they "leaf folders" (no sub-folders under them) or do they have sub-folders themselves? (I tested with a leaf folder Inbox/#maillist7 containing 17192 messages.)
