Thank you for the reply Christoph. I was able to retrieve the nextcloud.log and the horde_imap.log but couldn't find the smtp one, perhaps because I haven't sent an email out...

Sorry, wasn't thinking clearly. I sent an email and got the smtp log you need. [horde_smtp.log](https://github.com/nextcloud/mail/files/6658458/horde_smtp.log)

Hi and thanks very much @miaulalala for having a look. Is this something I could go in and fix up, somewhere inside the snap?

@miaulalala I don't know how the code works but I'm up for testing or anything else that may help. Thanks again.

@miaulalala I've added the function to - /var/snap/nextcloud/28088/nextcloud/extra-apps/mail/vendor/pear-pear.horde.org/Horde_Imap_Client/Horde/Imap/Client/Ids.php  The 'Error: A non-numeric value encountered etc'' has stopped in the admin loggging page, but still no messages at that point....

Thank you @miaulalala, that looks really interesting! I rechecked with 3 fresh Hanssen Nextcloud VM instances today, hoping that would get around any re-syncing issues without me taking a dive...
