I would like to automatically add a DKIM signature to all emails originating from an SME 7.3 Server.
There are hints that this may exist as a plugin (perl fragment / module) for qpsmtpd (see /usr/share/spsmtpd/plugins/dkim_sign, and domainkeys), but I have not found any documentation covering configurantion and use.
The wiki / FAQ / Server_Settings / qpsmtpd / Default Plugin Configuration makes no mention of these plugins.
Are they available? Are they currently being developed / tested for SME server use?
Is this the tool I should be trying to use, or is there an alternative?
We have problems getting emails delivered quickly to one or two business contacts who use Yahoo-related email accounts. Can we send some outgoing emails through an external ISP mail server, selected by outgoing email address to get around this problem?
