Hello,
on my dovecot-replicator-backend I see lots of panic-messages "assertion
failed: (ctx->nested_parts_count > 0)", produced from a single user.
I
assume that this is correlated with
https://github.com/dovecot/core/commit/a668d767a710ca18ab6e7177d8e8be22a6b024fb
How can I identify the incorrect formatted message in the user's
mailbox? I want to remove it, as the error-processes drive up the
backend's load incredibly.
Will a fixed dovecot-package be out soon?
Any help is appreciated.
Best regards,
Andreas
