The mailing list for listmasters using Sympa

[Thomas Barth <address@concealed>]

Hi,
I have configured two hostname, two different IPs for one server, and
two instances of postfix are running. How can I instruct sympa to use
the second instance of postfix for outgoing emails? It still uses the
first instance, incoming emails are handled by the second instance.

export MAIL_CONFIG=/etc/postfix2/ 

is set but not used. The second instance is also included in the first
instance as alternate_config_directories. Someone from the postfix group
told me that is the sending program's job to select the right MTA
instance. Any idea?
