Hi! On the latest versions (2.2.28, 2.2.29.x) we get crash on dovecot config parse. Error in config parser when checking namespace mailbox name. Reason: comma in mailbox name. Worked well in versions < 2.2.22. Do not know if it was working on 2.2.23-2.2.27, skipped this versions.
Example: namespace inbox { mailbox "&BB4EQgQ,BEAEMAQyBDsENQQ9BD0ESwQ1-" { special_use = \Sent } }
