I'm trying to diagnose a really strange situation where certain emails,
when submitted to the mailbox by Postfix, are not considered to be unseen
by Dovecot.
During testing, I've shut down anything else on the server that might want
to access the mailbox. I submit the email to the local postfix instance
which then says it has delivered it to the mailbox:
Dec 23 09:51:35 ip-10-35-194-108 postfix/smtpd[3283]: connect from
localhost[127.0.0.1]
Dec 23 09:51:35 ip-10-35-194-108 postfix/smtpd[3283]: 5A0BF40261:
client=localhost[127.0.0.1]
Dec 23 09:51:35 ip-10-35-194-108 postfix/cleanup[3286]: 5A0BF40261:
message-id=<20191223095135.5A0BF40261 at servicedesk.linaro.org>
Dec 23 09:51:35 ip-10-35-194-108 postfix/smtpd[3283]: disconnect from
localhost[127.0.0.1] ehlo=1 mail=1 rcpt=1 data=1 quit=1 commands=5
Dec 23 09:51:35 ip-10-35-194-108 postfix/qmgr[1660]: 5A0BF40261: from=<
philip.colmer at linaro.org>, size=702, nrcpt=1 (queue active)
Dec 23 09:51:35 ip-10-35-194-108 postfix/local[3287]: 5A0BF40261:
to=<local-it-support at localhost>, relay=local, delay=0.06,
delays=0.04/0.02/0/0, dsn=2.0.0, status=sent (delivered to mailbox)
Dec 23 09:51:35 ip-10-35-194-108 postfix/qmgr[1660]: 5A0BF40261: removed
I then use this command to query the state of the mailbox:
sudo doveadm mailbox status -u local-it-support all INBOX
and get this response:
INBOX messages=142 recent=0 uidnext=5596 uidvalidity=1455577845 unseen=0
highestmodseq=1163 vsize=11315688 guid=2a997739f55ac2560d180000e171d23e
firstsaved=1577094051
What can be happening that means that Dovecot doesn't treat a newly
delivered message as unseen?

ssl_cert = </etc/dovecot/private/dovecot.pem

}
Note that we are not using SSL because Dovecot is only accessible locally
within the server.
Thank you for any suggestions or comments.

In this case how do you expect dovecot to detect the new mai and update indexesl? change your configuration to use some more optimized mailbox format and configure postfix to deliver over dovecot-lda or lmtp.
