Hi,  
when an smime encrypted message comes in the mpa log shows some kind of id (maybe hash or serial) of the used certificate, if decryption fails in case of missing decryption certificate. I wonder if it might be also possible to get an id of the successfully used certificate if decryption was possible. Currently this is not shown for now. Is this maybe already part of another configurable log level?  
Thanks  
Philipp

Every incoming email gets a unique id (Mail-ID). This id can be used to  
group the log lines related to one email. This is particularly helpful  
if the gateway handles a large number of email in a short time-frame  
because log lines for different emails will be logged in chronological  
order. By filtering on Mail-ID, you can view only the log lines for one  
particular email.

The Mail-ID value is not related to the certificate. The gateway does  
not log the details of the certificate used for decryption. The  
certificates with which the email are encrypted are however added to  
the mail (see  
[https://www.ciphermail.com/documentation/faq/gateway.html#email-received-by-the-gateway-contain-x-djigzo-info-headers-what-are-these](https://www.ciphermail.com/documentation/faq/gateway.html#email-received-by-the-gateway-contain-x-djigzo-info-headers-what-are-these)  
for more information).

Kind regards,

Martijn Brinkers
