Yes, I will report back if it shows up again. Thank you, again!

Well, now it worked without any issues. Synced 2.1 GB and all folders without any errors at all. I first tried a few dummy folders, I created and put some mails in them. That worked also fine. After that, I tried all.... The weird thing is, that the same config produced the error yesterday and besides cleaning up the mail folder, I did nothing else. No idea how that happend... sorry! :-(

I will test that on both systems and report back.

In the initial report, I wrote version 1.3.5, because of the Arch package version, but the program itself is actually 1.3.3.

Thank you for your fast reply! I would paste the full logs, but I want to x out or cut down the personal stuff first. Maybe the following is enough (if not, please say so!) Reading configuration file /home/xxx/.mbsyncrc Channel Posteo Opening master store PosteoIMAP... M: [ 1] Enter connect_store Resolving posteo.de... ok Connecting to posteo.de (185.67.36.xxx:993)...
