I somehow ended up with multiple messages in the same mailbox with the same GUID. All of the messages are identical (AFAICT) but getting multiple responses for doveadm fetch for a particular guid is screwing up one of my applications.
When I searched for the offending guid in dovecot-uidlist I found this:
4927 :1632837493.M663171P23208.vm1.rngh.net,S=3942258,W=3993573 4928 G1632837493.M663171P23208.vm1.rngh.net,S=3942258,W=3993573 :1632880292.M915983P1968.vm1.rngh.net,S=3942258,W=3993573 4929 G1632837493.M663171P23208.vm1.rngh.net,S=3942258,W=3993573 :1632880303.M863130P547.vm1.rngh.net,S=3942258,W=3993573 4930 G1632837493.M663171P23208.vm1.rngh.net,S=3942258,W=3993573 :1632880303.M863131P547.vm1.rngh.net,S=3942258,W=3993573
I tried to figure this out by looking at:
https://doc.dovecot.org/admin_manual/mailbox_formats/maildir/
but this case doesn’t seem to be covered there. Can someone please help me figure out what might have happened to produce this situation? Is there a way to recover from it?
Thanks, rg
