[exim] Use of ipv4 and ipv6 for sending mails to specific do…

Hi list,

Situation:

we want to send emails to some domains only via IPv4 and to other domains via ipv4 and ipv6.

I tried to use the "interface"-value in the transport-section, but it didn't work.

I set an ip for the inferace-value by hand. The value was ignored and the Server used the default-IP for sending the email.

Config-Snippet:

transport_others:
driver = smtp
connect_timeout = 1m
tls_require_ciphers = ECDH+aRSA+AES128:DH+aRSA+AES128:ECDH+aRSA+AES256:DH+aRSA+AES256:RSA+AES128:RSA+AES256:RSA+3DES:RSA+RC4:!MD5
interface = IP-Address
helo_data = ${lookup dnsdb{ptr=$sending_ip_address}{$value}{$primary_hostname}}


So even if I set the interface to a single IPv4 Address the server uses the default ipv6 Address for sending the email.

Using dns_ipv4_lookup is not an option because I only would like to send via ipv4 to some specific domains.

Hope anybody can help me.

Best regards,

Thomas
