postfix mx backup for my costumer and smtp for my costumer
 

Hi ,

I have set up a postfix server for my costumers .

It acts as mx and smtp gateway .

the smtp gateway works , but mx backup said : relay access denied .

I rented a dedicated server for it so i have just only one public_ip

my main.cf

inet_interfaces = all
lmtp_pix_workaround_delay_time = 10s
lmtp_pix_workaround_threshold_time = 500s
local_recipient_maps =
local_transport = error:local mail delivery is disabled
mydestination =
myhostname = smtp.x.com
mynetworks = localhost.localdomain 127.0.0.0/8 my_ip_static_dedicated_server static_ip_from_mycostumer static_ip_from_mycostumer2 static_ip_from_mycostumer2
myorigin = c.com
smtp_pix_workaround_delay_time = 10s
smtp_pix_workaround_threshold_time = 500s
smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination, permit_mx_backup
transport_maps = hash:/etc/postfix/transport

My transport file

customer1.com smtp:mx.customer1.com
customer2.com smtp:mx2.customer2.com
...

My master.cf

Have you got any ideas ?

THanks :)


Ps: I know, i must set up sasl for gateway smtp but it's the next step :Pengy:

i think you should add domain names to mydestination = directive (separate by spaces) and restart postfix.

ex: mydestination = abc.com def.com
