Hello Jan,
JP> I try it for two days later... Can you help me what's wrong?
JP> mynetworks = 127.0.0.1, mysql:/etc/postfix/pbsp.cf smtpd_sender_restrictions
JP> = permit_mynetworks, permit_tls_all_clientcerts
OK, the next step is to find out WHY Postfix is refusing to relay.
This is best done with either the log, or (my preference) telling
postfix to send a message to postmaster for policy violations. I use
the following in main.cf:
# what to tell postmaster about
notify_classes= resource
software
policy
protocol
2bounce
bounce
The policy and protocol parameters will generate a message similar to
this when relaying is denied:

The important thing in this is what IP Postfix saw when the message
was presented to it. If it is 127.0.0.1, then stunnel is working, but
Postfix is not obeying $mynetworks.
If, however, it's coming from the "real" IP of the customer, then
they're not sending using stunnel, so the pbsp table is not correct.
In this case, they should either make sure their client is using
stunnel for both send and receive, OR switch to non-stunnel
connections for POP3/IMAP4 (probably not a desirable thing!).
