Hi,
My ISP is blocking outside SMTP connection except their own SMTP relay with
authentication, so
I've in /etc/transport
* smtp:smtp.domain.com:587 with SASL configuration to authenticate
I recently activated the IPV6 configuration on my BOX and I'm able to
connect to an IPV6 Address on port 25.
So I would like to use IPV6 for default outgoing transport and in case of
trouble, I want to use my current configuration with my ISP SMTP relay and
authentication.
I tried to use fallback_transport_map = /etc/transport_fallback with the
current configuration of /etc/transport and I changed in /etc/transport the
default transport to be
* smtp-ipv6:
The smtp-ipv6 is defined in /etc/master like this
smtp-ipv6 unix - - y - - smtp
-o inet_protocols=ipv6
postfix/error[8666]: 2AEACA0093: to=<n...@domain.com>, relay=none,
delay=656, delays=654/1.2/0/0.03, dsn=4.3.0, status=deferred (unknown mail
transport error)
What is wrong in my settings. Any help will be appreciated.
