I have been given the task to install Mailman3 for a large organization, where the list will send emails to 80-100K users.
First, you probably want to be asking on the mailman3 list- https://lists.mailman3.org/mailman3/lists/mailman-us...@mailman3.org/ (this list is mostly mailman2) and read some of the docs at https://docs.mailman3.org/en/latest/
1. How to do the hardware sizing and what should be hardware/VM configuration? 2. Should we install an email server ( Postfix) on the same server? 3. Can we use an external SMTP server like GMAIL/Office365 to route emails, is there any guide to configuring this?
Yes, maybe, it depends.... how many total lists? how many messages per day per list? to how many recipients? how big are the messages? how fast do they need to be delivered? Are the messages "personalized"? (Sending one non-personalized message once a day to 100k people is vastly different from sending 50 personalized messages to 50 lists, etc.)
Oh, and how much bandwidth is available to the server? In the best of times (and if my math is right), a 1gb/s 'net connection might only send 2k messages/second if they're small and the far-end servers are willing. (That is a complete WAG, but illustrative.)
4. How to avoid blacklisting of mailing list IPs?
Don't send spam, get the DKIM and SPF records right, avoid sending from IP addresses that are already in blacklists :).
