You should not use more IPs than necessary. A volume less than 10K per day per IP is too low. A volume of 1M per day per IP is on the upper end.
For a mailing list of 1M I would use a pool of 4 IPs. If you are an ESP I would create pools for groups of customers. And reserve the remaining IPs for customers that prefer dedicated IPs.
To warmup the reputation on the IPs you need to start with low volume, or split the volume using cold-virtual-mta and forward the remainder to another platform.
Make sure all prerequisites are in place: authentication, feedback loops, reputation monitoring, ...

As long as you dont change the domain itself,changing the subdomain on returnpath wont change anything in terms of reputation.

Hi, what is the best configuration to header return-path
At this moment we use the same for all ips of X.X.X.X/24 ie: Return-Path : <name@subdomain.domain.com> It's fine?? Or we should use <name@subdomain1.domain.com> ( X.X.X.1) <name@subdomain2.domain.com> ( X.X.X.2) <name@subdomainN.domain.com> ( X.X.X.N) where subdomainN.domain.com is the RNDS for the ip X.X.X.N Thanks!! |

HI, can you explain this??
If you are using PowerMTA 4.5r6 or later then you can also use mx-rollup-list feature to consolidate Microsoft related domains into one queue. This will improve resource utilization. For example, Microsoft EU and APAC : # Microsoft mx eur.olc.protection.outlook.com outlook-eur.rollup mx apc.olc.protection.outlook.com outlook-apc.rollup whereis hotmail.com Thanks!! |

In this BLOG post we discuss the implementation of a List-Unsubscribe header and share a use-case. For PMTA users we present an interesting add-on to streamline MAILTO unsubscribe requests.
