Hi Guys,

We have lots of SMTPs running on different IPs sending to many different 
destinations.

So what I need to do is, if any of this SMTP receives an email to specific 
destination, the mail must be relayed to a specific SMTP.

We work with named transports for this specific domains, so I guess that would 
be easy to do, I just don't know if postfix has this kind of support.

In my transport table I have something like this:

domain | destination
xyz.com | slow:xyz.com
abc.com | slow:xyz.com

We're having problems to deliver to specific destination because of too many 
opened connections from the same domain (its spread over lots of SMTP servers 
connection to the same destination, hitting the sending limits), so I guess if 
I just centralize this destinations in one only smtp having slow deliveries it 
might solve the problem.

Can anybody give me a tip of how to do this?

Thanks in advance.

BR,
