EV - Failed External Filter
I have an issue whereby around 3 times daily a number of messages are placed in the failed external filter folder over a period of approx 3 mins. There does not appear to be any common thread with the messages, and they are not messages which should be discarded.
I have only one rule in the filter which is to HARD DELETE messages from specific senders (approx 15 senders in the list).
I get a number of errors in the logs, and a sample of these is attached.
If I drop the messages back into the inbox, then they process correctly.
All messages are from the journal.
I have seen a number of threads regarding this but none seem to apply.
Any pointers appreciated.
