1626890 - Auto-forwarding incoming Messages (with Filter Rules) fail if incoming Message has been signed/encrypted by Sender

Status: UNCONFIRMED

(Thunderbird :: Filters, defect)

Description

[<NULL>]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:68.0) Gecko/20100101 Firefox/68.0

Steps to reproduce:

On a standalone computer with Thunderbird we have set up a filter rule that automatically forwards all incoming messages to a variety of recipients.

Hereby we have observed two problems:

1.) If the initial sender of the email has signed/encrypted his message, the filter rule won't get applied, so in consequence nobody will receive the incoming message.

2.) If the default mode of Thunderbird/Enigmail is set to automatically sign all outgoing messages, the mentioned filter rule won't get applied as well.

Actual results:

Observed behavior:

1.) Filter rule (forwarding message to recipients) won't get applied if sender has signed/encrypted his message. Even all PGP-keys are accepted correctly.

2.) Filter rule (forwarding message to recipients) won't get applied if Thunderbirds default behavior is set to automatically sign outgoing messages with PGP-key of the account identity.

Expected results:

Expected behavior:

Filter rule (forwarding message to recipients) will be applied, even if sender has signed/encrypted his message.

AND

Filter rule (forwarding message to recipients) will be applied, even if Thunderbird is configured to auto-sign all outgoing messages with PGP-key of the sending identity.

We have experienced this issue in Thunderbird version 68.6.0.

So it worked in version 68.5.0? If it did, what was the first version you noticed it wasn't working, or the last version you remember it was working.

Unfortunately we didn't try this in previous versions... :-(

For 68 PGP is still through Enigmail.
