Hi, imapc does a lot of UID FETCH $UID (BODY.PEEK[]), which is nice, because it works even with the dumbest IMAP server, altough it really kills performance, especially on high latency lines. I wonder: if IMAP servers can effectively handle boundless fetches (like a list with all wanted UIDs, or simply 1:* if all are needed), do you see this as a good addition to develop? This could be a

Hi everyone, Can someone explain me why dsync need read-write access to source box when pulling data (dsync -R backup)? I am working on migration from Dovecot 1.x with maildir to latest Dovecot 2.2.15 with mdbox and found that there is no way to do this from ro filesystem (got "failed: Read-only file system" on access to /dovecot.index.log).
