Hi,

I tried to send mail with cone (1.1) via SMAP (Courier 1.0.14, Courier-IMAP 5.0.11), but noticed two problems:

a) zdkimfilter does not produce DKIM signatures. According to the log files, it instead tries to verify. Outgoing messages coming via SMTP are signed fine; this problem seems only to affect messages that are sent through SMAP.

b) The Bcc-Header is sent to all recipients (To- and Cc-Recipients can see who is in Bcc).

What could be wrong here?

I am not familiar with how zdkimfilter works, so I can't say for certain. With this kind of a configuration the E-mail (from the mail server's standpoint) originates locally, and perhaps zdkimfilter is configured to sign only mail that's received via SMTP (from a client).

Yes, according to zdkimfilter's documentation, "The signing domain can be inferred in two ways, either by SMTP authentication or by setting RELAYCLIENT."

Do I have a way of setting RELAYCLIENT for messages that originate locally?

As far as the bcc header goes, this should be suppressed in build 20201028, at http://www.courier-mta.org/download.html#cone

Thanks, but does this mean, that the message is transmitted twice now (on version for sending and another for the Sent folder)?

best regards,
Daniel
