Dear,

I have a question how to relay only some domain to another mail server with ssl connection, because we always reject if we send an email to that domain.

Maybe this is the scenario :

only the domain
iredmail > smtp relay server > domain destination

For oher domain
iredmail > smtp iredmail > other domain

I already try on this link http://www.iredmail.org/forum/topic334- … tion.html, but i still confious because i am newbie with postfix.

Regards

Looks like you need "sender_dependent_relayhost_maps" for outbound relay:

Re: Relay one domain only to another server

Dear,

Is the config change at /etc/postfix/main.cf ?
example :
#relayhost = $mydomain
#relayhost = [gateway.my.domain]
#relayhost = [mailserver.isp.tld]
#relayhost = uucphost
#relayhost = [an.ip.add.ress]


for relay :
relayhost = $domain_destination
relayhost = [smtp.relay]:25

What should i change again to relay just oone domain which reject by recipient?

Best thanks
