Hello,

I see the same issue, but in addition the mails seem to be dropped (at least 
don't arrive on my Google account):

2025-10-22 08:17:56 1vBSAQ-006Ylq-0V Completed

(I annnonimized my email addresses)

The entries in rejectlog are all older and I do not get any message back from 
Google.

I am running 4.96 on a Debian 12 system.

Does anybody else see that?

Any idea or hint how to debug this is welcome.

Thanks
Rainer
