net-mail/isync-1.3.0 has been in tree since October 2017. For what concerns me, it includes new configuration option "SubFolders". Below is upstream changelog since 1.1.0 (current stable). Thanks in advance. [1.3.0] Network timeout handling has been added. Support for proper Maildir++ and a Maildir sub-folder naming style without extra dots have been added. Support for TLS client certificates was added. Support for recovering from baseless UID validity changes was added. The get-cert script was renamed to mbsync-get-cert. [1.2.0] The 'isync' compatibility wrapper is now deprecated. An IMAP Path/NAMESPACE rooted in INBOX won't be handled specially any more. This means that some Patterns may need adjustment. The default output is a lot less verbose now. The meanings of the -V and -D options changed significantly. The SSL/TLS configuration has been re-designed. SSL is now explicitly enabled or disabled - "use SSL if available" is gone. Notice: Tunnels are assumed to be secure and thus default to no SSL. Support for SASL (flexible authentication) has been added. Support for Windows file systems has been added. Support for compressed data transfer has been added. Folder deletions can be propagated now.
