User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:94.0) Gecko/20100101 Firefox/94.0

Steps to reproduce:

When I revive an mail signet via s/mime using outlook, then the mail is marked as altered. But when I save the mail as an eml and check it via "openssl smime -verify ..." then the mail is shown as ok:
openssl smime -verify -in 2.eml -out /dev/null
Verification successful

When the mail was send via outlook and it was signet and encrypted, Thundebrid can decrypt it correct, but also show the warning about the altered s/mime message.

Actual results:

The received mail is marked as alerted. (See picture)

Expected results:

That Thunderbird also accept the message as correct signet.
