one of our clients receives encrypted emails with a single small text attachment, send by

The problem is, that after decryption, the attachment seems to have disappeared. Since
the attachment only contains one or two lines of text, it isn't helpful to compare the
size of the email before and after decryption.
Do you have the MIME source of a message after decryption? or is it
Are there any error messages in the MPA log?
Which loggers do I have to switch to debug to see,
what happens to the attachment?
Since there is a large number of other emails with attachments, which are decrypted
correctly, I doubt that it is a Djigzo problem. But at least we have to proof it.
The first thing to find out how you can detect which mails should be
watched for. One option would be to add a matcher/mailet to config.xml
which matches for a specific recipient and then send a copy of the email
to some other address before and after decryption.
You might also do this in Postfix I think with recipient_bcc_maps
Then if you have the message source before and after decryption we can
further analyse it
