I want to set up an outgoing transactional email server for my small business. Do I need to purchase IP blocks? Given most IPs from VPS will have bad reputation.

Please respond only if you have ran an SMTP server. Not looking for heresay.

    I’ve ran postfix/dovecot for email in the past. Postfix would be the more important one as it’s the MTA. You’ll need at least one IP and a DNS registrar. That stuff isn’t so bad, the tricky part is ensuring your email doesn’t get sent straight to spam. I also configured dmarc, dkim, spf, etc to make sure my server was verifiable.

    From what you’re saying; 100k emails a month from a new mail system is gonna get you on a spam list or blacklist. If no one reports you it might not be an issue. I don’t know if ISPs limit that stuff.

    If you’re good with this stuff. You should be up and running in a day or so, but I’m curious to see how long the operation lasts. Most postfix how-to docs can get you started
