The email are probably still in the MPA outgoing queue
(or in the MPA
error queue if there was a problem delivering the email). The MPA
outgoing queue is the queue of email which are being sent back from the
encryption engine. Normally they are sent to Postfix on localhost:10026
but with your changes they are being sent to localhost:10025. LMTP is
AFAIK not compatible with SMTP (minor differences but enough to not be
compatible I think). If MPP uses the LMTP protocol, try to change it to
use the SMTP protocol.
thanks for your suggestions.
But before I try to change MPP, I will change the way emails are handled:
There is a linux gateway in front of the email server and I will install Djigzo there.
The only disadvantage is, that I have to setup a cronjob to copy the fetchmailrc from the
server to the gateway because our client changes the email accounts quite often.
But that's easier than messing around with MPP.
