Since you tried to fix your SMTP mail on April 18, it got blacklisted again. Are you guys capable to find out who sending out spam mails from your account to keep your smpt being blocked? or everyone using your smtp for sending email should look for a new hosting?

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its

host []: 550 5.7.1 The IP address was rejected by the Realtime Block List provide

p.s. I already request a delist from, as I really need to send out email to reach them.

We do apologize for the email issues. I reviewed your current email log and I couldn't find any particular notification of being blocked by the RBL. This doesn't mean that the problem is not there, but we need more information from you to really check it. Can you please provide the email address that you are sending to? We can then verify it and send the issue up to systems for immediate correction. Or it's possible that your de-listing efforts have already taken place.

If you wish to keep the information private, then please email the issue directly to our technical support team - as they can handle the issue directly without posting to our public forum.

If you have any further questions, please contact technical support available 24 hours a day / 7 days a week.

Biz117 got listed today! I moved my host... And tomorrow I start moving every one of the 22 customers that I have hosted there... I do computer consulting for small businesses and his morning I had 8 of the 22 customers who could not send mail... What a great way to start a week... Monday after Father's Day and phone ringing off the wall from unhappy customers who can't send mail, and it's nothing but putting faith in an incompetent provider. Gonna blast 'me on every blog I can. Last year the webservers got hacked... Not widespread smtp blacklisting? I used to work for an ISP and that server admin would be lookin for a new job!

Hello Bigtechhouston,

I'm sorry to hear about your email issues and that you have experienced issues with email and the hosting service to the point that you are moving hosts. It is unfortunately a fact that spam is on the rise, and that attacks on hosting services have also gone up. InMotion Hosting as a hosting company take all of these matters very seriously, and have been taking steps to help prevent email issues from affecting our customers. Our steps to secure our servers for both spam (inbound and outband) are one of the primary ongoing initiatives for the Systems team. Our email and hosting services are not perfect, but you will find that most any hosting service face the same issues. It appears that you were hosting websites with InMotion Hosting, but you where hosting using shared server level accounts. If you wanted to isolate your customers, one of the possible solutions was to upgrade hosting and get a VPS or dedicated server account where you would have complete control over the reputation of the mail server. If you were to get blacklisted at that point, it would be happening due to something within your customer's websites.

Again, I do understand that your choice of a web hosting service is a choice. I wanted to present a possible solution if you wanted try it, and also provide you a more official avenue of suggestion or comment. The use of a dedicated server is the best way to ensure that there no other possible factor for server getting blacklisted, except your own accounts.

Communication to goes directly to our managers. I know that this does not provide a solution, but if you do have some time or want to re-consider moving hosts, please consider these options.

I appreciate your response, and your VPS solution and/or moving the mail to google were both options offered by the ts rep I spoke to today. In response, I am curious as to the amount of customers actually decide to buy MORE services at a HIGHER monthly rate after experiencing issues by the fault of the provider that render the current services offered unusable. This morning I was in the process if emailing final copies of a 3 year contract for computer consulting services that I had been grooming a customer and working on getting the deal signed for 3 months after 3 telephone calls to my client and sending the message 3 times I realized that the message were being bounced because MY host was blacklisted by the clients provider. Honestly, it made me look unprofessional and almost cost me the deal.
Also, there are plenty of providers out there that don't have these issues. The fact that http was compromised last year and hundreds of sites hacked and defaced, not the widespread blacklisting leads me to believe that the boxes are not being managed and monitored properly. I can tell you that I have been building and supporting customer websites, managing customer networks, and providing IT support for 20 years. "Back in the day" errors like "relay denied" were common and were always the fault of the admin of the server. I can tell you that of the hundreds of customers I have supported and the thousands of issues I have seen blacklisted sendmail servers are not a common occurrenceare are ALWAYS the result of poor network policies and monitoring.
I have been with InMotion a long time and honestly hope to see you guys get these issues worked out but I insist that running mailservers without dealing with relaying and returned mail issues in "Internet Service Provider 101" and I have to move on... PS - I tried calling support tonight to get some things don't to move a few hosts and hung up after an hour. Good luck to you guys... I honestly do feel your pain!
