Email Error .. my ip public blocked
-
I think Scott is over selling this here - but then again he's a complete fan of hosted email.
While Blacklisting can and does happen to those that are self hosted - it's really not that common unless you have other issues - like someone on your network starts sending our spam on the same IP that your email server is registered for, or you're using a dymanic IP with no PTR as Scott mentioned.If possible get yourself a static IP that is ONLY used for email and most of those problems will go away.

Like hosting your own email server

The problems with self hosting are cumulative. I know of no one hosting their own email system that isn't regularly hit with blacklists. Of course, I've dealt with no business willing to do this in over a decade, the issues were so intense that the idea has finally fizzled out and no longer exists in the business world in the west. Those that want the "feel" of self hosting email do so by running Exchange in house but having a mailbagger running in the hosted space as the real email server (MXLogic, Postini and similar services.) They are the actual email servers and so the email is hosted, the mailboxes are the only part that are local (which are post-email services, excuse the pun.)
When you self host you are dealing with lots of issues that while not absolutely necessary, generally occur:
- Lack of knowledge of email systems (or else they would be hosted) leading to more issues below
- Lack of PTR and other important security records that need understood and maintained
- Lack of patching, system updates and other issues that can lead to being out of date with standards (or breaches)
- Dynamic IP addresses or using address pools that are blacklisted. Entire ISPs are blacklisted so this is very possible.
- Being in a country that is often blacklisted! Very little to be done about that one.
- Bad user behaviour.
- Malicious competitors who report you and get you blacklisted. This isn't always a technical issue.
- Accidentally having an open relay either on your email server or possibly even on another server.

Yes, we've found it to be very nice for having quick, effective conversations. It's so easy to respond quickly and see what other people are doing. Other sites I have found the same conversation can take all day that only takes a few minutes here. You can bring up the response windows quickly, type quickly, no site delays. And other people see what you post almost instantly.
At other sites it takes me easily ten times as long to post a response and then since I never see anyone else respond I have to wait for an email to come to me to tell me that someone responded and often that takes 30 minutes or so from the time that they post something until the email sends! So getting help on other systems can take forever. Here it is like a flowing conversation.

Here is a tool that you should be using regularly:
http://mxtoolbox.com/blacklists.aspx
Put in your email server details there and it will check the major blacklists to see who is blacklisting you. When your email is healthy, no one should be blacklisting you.

My employer has been hosting their own email since 1999, when they got email. I took over support of those system in 2001. Since that time they've been on a black list exactly one time.
Maybe you can count me as someone you know now?

You send directly from your own email system and don't have a front end hosted somewhere like Postini or MXLogic?

Yes I send direct from my own machine and No I don't have a front end like Postini. But I do use AppRiver to receive all of my email to filter out spam and virus...

Your SMTP doesn't connect to AppRiver? Isn't that included in the service?

wht is AppRiver ??

AppRiver is a competitor with MXLogic and Postini. They have a nice service. They handle sending and receiving your email so that your Exchange server does not need to talk to others directly. When they receive email they handle spam filtering and antivirus so that you do not have to. And they receive email and store it for you even if you are not online.
They can also handle sending email for you. So you send to them and then they send to others so that they handle making sure that they are not blacklisted.

good to know that, and you pay per user or only one time payment no matter how much user you have ??

Last that I knew, AppRiver was per user. I have not used one of these services in a while because we use Office 365 here which includes that type of service automatically.
-
noted .. will bring this up to next meeting
-
Just for some reference...
Generally having a service like MXLogic, Postini, AppRiver or similar is going to be about $2/user/month.
Having Office 365 which gives you all of that plus your entire Exchange server, storage, backup and support is just $4/user/month.
So typically you will find that having the first service doesn't make sense as much as having Office 365, Google Apps or Rackspace Email because they are just so cost effective.
Prices are in USD. You'll need to check the cost in your local currency.

No it's not included - that's an additional fee - or at least it was 10 years ago when we signed up. At this time I'm not sure what it would gain us by sending email out though them? again we've only been on a blacklist once in since 2001.

That's just crazy. I can't believe you've never faced blacklisting. It used to happen so capriciously.
