Can’t resist jumping in here :)
Yes, can’ agree more – run the mail systems yourself. Sendmail is still very popular and widely adopted, however totally agree on personal preference of Postfix. It’s part of being an ISP in my opinion .. DNS, Mail, Authentication etc are no different than managing the network. RBL’s – I checked around our operation to see how often this comes up… we probably handle about 15-20 requests a week (pretty small) and find that half of them are bogus anyways.

Just the same as you should have the technical acumen to administer BIND and create your own zone files for your domain, it's necessary to know how to deal with email. There are things you may need to do with a combination of your email system and custom aliases/redirects and your in-house ticketing system and monitoring that are incompatible with most third party email services. I agree with your points on #2 and #3, my email setup (postfix + dovecot with plugins for openDKIM, SPF verification and spamassassin) is not hosted on an incredibly redundant platform, yet it's still met better than five nines availability for the last several years. I have full flexibility on what platform it runs on and can in an emergency move it to another set of machines or another hypervisor. I own the hardware that it runs on and have root on the hypervisor that it runs on. #5 is trivially easy to deal with as I do not provide email services for customers (whose machines may be compromised/passwords stolen), and do not run an open relay. I need a "team" to stay off blacklists? If I need to pay more than 5 minutes/week attention to RBLs for my smtpd and IP space something has gone terribly wrong. #9 - sendmail? seriously? save us from sendmail, there's a reason why >35% of the recently deployed debian and/or centos/RHEL based smtpd on the net use postfix or a more modern smtpd. #10 - if I wanted to offer hosted email it would get its own email server and a web based email access system running on a LAMP server like roundcube or rainloop.

Sendmail has been used by a metric asston of ISPs - potentially serving several billion customers over the years. It is very well tested and supported. [10] As a small to medium ISP, if you INSIST on offering hosted mail to customers and don't like Sendmail, consider Zimbra. Zimbra will offer you support and features very similar to Exchange with a much lower cost. Your end user devices won't know there is a difference. Somebody is going to come up with certain experiences they've had running Exchange, or Qmail, or $whatever. That's fine, you experience and opinions are no less relevant. Now I'm going to bow out, and maybe watch the carnage unfold after I finish making this new ansible/Juniper playbook :) On Wed, Jun 1, 2016 at 1:13 PM, Dennis Burgess <dmburg...@linktechs.net <mailto:dmburg...@linktechs.net> > wrote: > 1.. exchange is easy. > 2. why works great! > > > > > www.linktechs.net <http://www.linktechs.net> – 314-735-0270 x103 – > dmburg...@linktechs.net <mailto:dmburg...@linktechs.net> > > -----Original Message----- > From: Af [mailto:af-boun...@afmug.com <mailto:af-boun...@afmug.com> ] On > Behalf Of Josh Reynolds > Sent: Wednesday, June 1, 2016 12:52 PM > To: af@afmug.com <mailto:af@afmug.com> > Subject: Re: [AFMUG] Urgently need Exchange DB Guru > > [1] Good luck with getting it fixed > > [2] Get the fuck off exchange > > On Wed, Jun 1, 2016 at 12:38 PM, Gino Villarini <ginovi...@gmail.com > <mailto:ginovi...@gmail.com> > wrote: >> thanks! >> >> On Wed, Jun 1, 2016 at 1:35 PM, That One Guy /sarcasm >> <thatoneguyst...@gmail.com <mailto:thatoneguyst...@gmail.com> > wrote: >>> >>> Keith Willis with Progent >>> >>> On Wed, Jun 1, 2016 at 12:32 PM, Gino Villarini <ginovi...@gmail.com >>> <mailto:ginovi...@gmail.com> > >>> wrote: >>>> >>>> We have a issue with our Exchange server.
