This morning I noticed e-mail out of sequence.

I looked in /var/log/mail.log and postfix seems to have handled them correctly, recording the same things for them as any other e-mail, and in sensible sequence with the surrounding timestamps.

But in my e-mail client (Thunderbird) some were delayed when viewed as I always do by "Order Received".

These are the examples I noticed, when compared to surrounding messages:

• 1 delayed ~3-hours, then 4-hours after that…
• 7 delayed ~16-hours, followed immediately by…
• 2 delayed over 5-hours.

Other notes:

• Thunderbird was not running at the time that these came in (that computer was asleep).
• I am running dsync between two servers and both servers show the same details in Thunderbird (so syncing seems working).
• I don't notice any dovecot errors in the log in the vicinity of when the delayed e-mails were processed by postfix, nor when the surrounding e-mails were processed by postfix.
• There were no reboots during this period.
• I do see some other little timestamp "errors", but these seem to be mailing list messages getting an internal timestamp a couple minutes before the message got delivered to my server (I also will see spam with completely false timestamps, but that it not what is going on here).

Does Dovecot sometimes not notice new mail?

Thanks,
