Riposte solution
NOMODSEQ means the server does not support tracking modifications for this mailbox. As a result, you cannot use mod-sequence based sync (QRESYNC) on it. Riposte will detect this and avoid modseq-dependent operations. It might have to revert to full sync checks for changes. No direct fix—it's a server limitation; just be aware that incremental sync might be less efficient for this mailbox.
