      Been very happy as a Zimbra user. Straightforward to use for sure.

          Lol now Scott seems to be advocating for self hosted email.

          I agree with you, what an u-turn @scottalanmiller !

                All the Zimbra Servers we have are either hosted locally or cloud based.

                    What's the other option?

                      @scottalanmiller It is a Chilean hosting company, that doesn't host Zimbra for email.

                              Comcast Webmail is also using Zimbra.

                                Not the best endorsement.

                                  Just following up. We've been using Zimbra now for quite some time more. It's been another year. The product has improved slightly, we've had a few hiccups in patching and cert management (their system is ridiculous, but it is scripted by now.) We have improved SPAM handling dramatically. We went through an IP black list and added MailGun to handle our outgoing email reliability which has been great.

                                  Overall, another year and extremely happy with being on Zimbra.

                                    Where you on a shared IP? If not, why were you having blacklist problems?

                                      No, not a shared IP. That's not how Microsoft and Spamhaus do blacklisting. It has nothing to do with abuse from your IP. They block indiscriminantly.

                                        My Open Source solution of choice is Mailcow. But I am looking for a good relay for cPanel and I am considering the obvious: MailChannels. But open to options.
                                        MailGun Pay as you go looks interesting but I have read that some users have experienced some intermittent relay denials. I am guessing that they are on the free tier.
                                        Are you on the Pay as you Go plan or other? Any problem whatsoever?

                                          I'm not sure the name of the plan, but we pay per email sent. Which comes out to something silly like $3 a month.
