It could be it tried to update both mailboxes. I don't know what thunderbird does in the background when you're not actually clicking on a mailbox. The errors were visible in both maillogs (server1 and server2). But I can reproduce the problem by connecting only to server1, in that case, the errors show up in server1's log only: the current test scenario looks like: - both servers empty mail store, configuration set to mdbox - start server 1 - start server 2 - connect claws mail to server1 - connect thunderbird to server1 too - in claws mail copy a few hundred mails from a remote box to server1 - I can see the unread counter go up in thunderbird - "Remote didn't send mail" errors start popping up, but only in server1's maillog this time - mails are duplicated in one testrun I also saw the assert failure below, but again, I can't reproduce this one : Jan 31 18:10:11 doco1 dovecot: doveadm: Error: dsync-remote(user1): Panic: file dsync-mailbox-import.c: line 1080 (dsync_mailbox_import_change): assertion failed: (change->type == DSYNC_MAIL_CHANGE_TYPE_SAVE) Jan 31 18:10:11 doco1 dovecot: doveadm: Error: dsync-remote(user1): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x5ce8a) [0x7f0ac3602e8a] -> /usr/lib64/dovecot/libdovecot.so.0(default_fatal_handler+0x32) [0x7f0ac3602f72] -> /usr/lib64/dovecot/libdovecot.so.0(+0x1f55a) [0x7f0ac35c555a] -> /usr/bin/doveadm(dsync_mailbox_import_change+0x501) [0x42c631] -> /usr/bin/doveadm(dsync_brain_sync_mails+0x3a2) [0x4290a2] -> /usr/bin/doveadm(dsync_brain_run+0x169) [0x425e09] -> /usr/bin/doveadm() [0x426360] -> /usr/bin/doveadm() [0x434780] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x36) [0x7f0ac3611a16] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0xa7) [0x7f0ac3612aa7] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x7f0ac36119b8] -> /usr/bin/doveadm() [0x424114] -> /usr/bin/doveadm() [0x40fe4f] -> /usr/bin/doveadm() [0x41067d] -> /usr/bin/doveadm(doveadm_mail_try_run+0x141) [0x410ba1] -> /usr/bin/doveadm(main+0x3f1) [0x417ba1] -> /lib64/libc.so.6(__libc_start_main+0xfd) [0x7f0ac3231cdd] -> /usr/bin/doveadm() [0x40f839] -- message transmitted on 100% recycled electrons
