There is nothing unusual about the message numbers: to essentially guarantee a unique number, Qmail uses the inode address (inode number) of the file as the message number.
Your inodes are being used and released as normal, and there are blocks the get reused over and over Dan From: Chris [mailto:boh...@gmail.com] Sent: Thursday, January 11, 2018 9:22 PM To: qmailtoaster-list@qmailtoaster.com Subject: [qmailtoaster] Odd msg numbers in /var/log/qmail/send/current While tracing a message today, I noticed something weird. A strange distribution of message numbers. running this command: grep 'end msg' /var/log/qmail/send/current | awk '{print $4}' | sort | uniq -c | sort -n I got this result, which indicates that I'm not getting an even distribution of msg numbers. I know this isn't a case of some messages getting stuck in the queue and having repeated delivery attempts, because I checked for that. Anyone else notice this before? 1 1169605 1 485974 1 485993 1 485994 1 518835 1 598620 1 598621 1 598622 1 598623 1 871911 2 871910 3 522872 3 598618 3 598619 4 598617 5 518834 5 598612 5 598615 6 485973 7 485972 7 485991 7 598614 8 485971 10 485970 11 598608 12 485990 12 598611 13 485968 13 598600 14 518833 14 598613 15 485989 16 598606 16 598610 17 403440 17 485969 17 485988 21 598609 33 518832 41 485987 47 485965 51 485975 53 485983 54 485967 55 485986 59 485977 60 485966 61 485985 87 598607 107 522877 163 160176 168 485978 171 485976 188 485984 240 485981 255 485979 268 598599 280 485982 290 526373 406 485980 559 536520 627 485963 770 160177 1356 485964
