Hi I new on IredMail, and I migrating from Qmailtoaster, we have around 80k mailboxes, and 130 domains aprox, I'm choosing to buy the pro version for this reason, I have no problem on the migration progress so far, but I have a problem, I need to  balance outgoing emails via multiple IP addresses for reputation problems, I found a solution with postfix`s TCP_TABLES and a perl script
Example Link but whenwhen i check my installation, I get the following

[root@mail1 ~]# postconf -m
btree
cidr
environ
hash
ldap
mysql
nis
pcre
pgsql
proxy
regexp
static
unix

So basically I have not TCP Table support, someone has already done this, or has any idea how to do it?

From now, thank for any feedback.
