It's easier to do with a src-nat within network gear.
I understand, I just wanted to know if there is an intelligence way to bind
every ip address its own helo.
But let me tell
you that this is referred to as "snowshoeing" as it expands your IP
footprint, and is seen in the deliverability world as a slimy thing to
do.
People do it to mitigate the effects of their IP addresses being
blacklisted. But the cleaner solution is to ensure that the mail
egressing from your platform shouldn't warrent a ban.
Also some systems have too high limits, so legitimate mail is delivered with
delays...

Hi, can someone give me a hint how to randomly spread outgoing smtp traffic
over pool of ip-addresses?
As I understand it's necessary to create several transports and use
transport tables, but I do not see a way how to make lookups truly random.
smtp1 unix - - n - 100 smtp -o
smtp_helo_name=smtpout1.do -o smtp_bind_address=1.1.1.1
smtp2 unix - - n - 100 smtp -o
smtp_helo_name=smtpout2.do -o smtp_bind_address=2.2.2.2
smtp2 unix - - n - 100 smtp -o
smtp_helo_name=smtpout3.do -o smtp_bind_address=3.3.3.3
