Hello,
A customer is using his SMTP account on SM to send copier scans both to a local SM mailbox and also to an external mailbox.
With build 8930 it was working flawlessly.
Now since we're running the latest builds (6965+) these kind of mails are stuck in Waiting to deliver. In "view recipients" it shows Error: 0 for the external recipient.
In the delivery log it shows:
[2024.08.10] 08:33:50.614 [27167614] Exception: Incomplete parameter at offset 26
Exemple of the delivery log entry.

Any idea what's going on ?
PS: We use an outgoing gateway. But still, it was working correctly with 8930 build and earlier...
Kind regards.
