I've sniffed traffic between exim and lmtp In log of dovecot I have: 17:17:46 msgid=<e1qwtg6-0002o6...@pink.example.com>: G48FNNjoVU63IwAA1nFjLA: 17:17:51 msgid=<e1qwtg6-0002o6...@pink.example.com>: HI8FNNjoVU63IwAA1nFjLA: 17:17:56 msgid=<e1qwtg6-0002o6...@pink.example.com>: gY8FNNjoVU63IwAA1nFjLA: 17:18:01 msgid=<e1qwtg6-0002o6...@pink.example.com>: 5o8FNNjoVU63IwAA1nFjLA: 17:18:08 msgid=<e1qwtg6-0002o6...@pink.example.com>: S5AFNNjoVU63IwAA1nFjLA: 17:18:13 msgid=<e1qwtg6-0002o6...@pink.example.com>: sJAFNNjoVU63IwAA1nFjLA: 17:18:18 msgid=<e1qwtg6-0002o6...@pink.example.com>: FZEFNNjoVU63IwAA1nFjLA: 17:18:23 msgid=<e1qwtg6-0002o6...@pink.example.com>: epEFNNjoVU63IwAA1nFjLA: 17:18:29 msgid=<e1qwtg6-0002o6...@pink.example.com>: 35EFNNjoVU63IwAA1nFjLA: 17:18:31 msgid=<e1qwtg6-0002o6...@pink.example.com>: RJIFNNjoVU63IwAA1nFjLA: Totally 10 different lmtp ids.
