Re: multiple relay servers

[Zsombor B]

Hi Wietse,

Postfix 3.5 supports multiple relayhosts:

Currently we are on 3.2

If these folks want to receive mail in six places, why can't they
set up DNS records like everyone else does?

I'm already over this discussion, that's why I have asked the question. :(
Big company, rigid people, dumb rules.


Thanks,

Hi All,


Customer asked us to relay their mails to a specific smtp server.

Actually they provided 6 possible destination servers.


When add them to sender_dependent_relayhost_maps postmap complains
that there are duplicate entries:

@foo.bar [mail1.whatever]:123
@foo.bar [mail2.whatever]:123
@foo.bar [mail3.whatever]:123

There can be only one table entry with the name @foo.bar. The
postmap command ignores the rest with a warning.

How can I solve this?

Postfix 3.5 supports multiple relayhosts:

transport_maps example:
    example.com relay:[mail1.example]:123, [mail2.example]:123, ...

sender_dependent_relayhost_maps example:
    @foo.bar [mail1.example]:123, [mail2.example]:123, ..

This is a fixed order (as if you had multiple records in /etc/hosts).

If these folks want to receive mail in six places, why can't they
set up DNS records like everyone else does?
