Re: Sending Bulk Mail - Own SMTP mail server on VPS vs 3rd Party Mail Service

I've had good service from Linode as a hosting provider. SPF, DKIM and DMARC took me quite a while to configure, attributable mostly to lack of experience. I need to revisit my spam problem, yet again. The current solution is still CRM114, which is keeping most of the spam at bay, but introducing too many false positives. I've tried rspamd in the past, as well as SpamAssassin, with worse results than CRM114 is currently giving. I've also successfully used Mailman on the server, but for a very low traffic mailing list.
