Re: ot: how to t/s TBird problems ?
Even more easy, start by examining the mail headers to see where the mail was blocked.

Re: ot: how to t/s TBird problems ?
Hi! This is very unlikely to be a dovecot issue itself. There is nothing inside dovecot that would horde your emails for 2 hours before "delivering" them. You should - Enable mail_log plugin. This will tell you when mails are delivered, when deleted etc, see https://doc.dovecot.org/configuration_manual/plugins/mail_event_logging/ - Examine your logs - Check `doveadm fetch 'date.received date.sent date.saved' mailbox INBOX '*'` ( this will print you the last email in INBOX, note the quotes) Aki > On 23/10/2022 16:49 EEST Chris Wensink > wrote: > > > Over the last several months we have seen what seems like large delays in > email delivery as well, we get emails at 11AM that are time stamped at 9:10. > I thought it was a networking issue, but I can’t be sure.

Re: ot: how to t/s TBird problems ?
Over the last several months we have seen what seems like large delays in email delivery as well, we get emails at 11AM that are time stamped at 9:10. I thought it was a networking issue, but I can’t be sure. I wish I knew more about coding, to look under the hood to examine things further.

Joseph, thank you very much for the follow up! you won't believe it, literally minutes before your email I got this email from the 'problem user' (below) thank you to all who responded! - I guess if TB debug log was enabled (as was suggested)- maybe the issue would become apparent from TB debug log ? - I guess i should encourage POP users to switch to IMAP anyhow ? got this from problem user: --- Mozilla Thunderbird released an update which I just installed. Problem solved. I guess Tbird had a problem that the new release addressed. I'm sorry for the inconvenience. I'm mystified why my issue was only with one account. Perhaps it was something to do with the size of the database. --- yesterday it was --- I'm still experiencing a 40 second delay to retrieve emails for xxx I have changed the pop port to 110 for the server but that did not work at all. I have reinstalled my email client TBird but no change, anyway all the other accounts on TBird are working ok but they are MAPI not POP. Voytek

Hi Jeff, On Sat, Oct 22, 2022 at 09:05:42AM -0400, Jeff Koch wrote: > We had the same problem starting around October 14th - 'unsupported > encryption type' - we were running Dovecot 2.2.32.

I have to reinstall the whole machine. The explained behavior is a bit odd, because if the user replace the hostname of the IMAP/POP server by the IP address of the server at the settings, then client notices him that the certificate is non-valid (because of the FQDN), but after it works... Thanks, a.
