Major Mail Rejected Problems
Question asked by Francis Gibbons - 4/3/2016 at 7:27 PM

Hello All,
 
I am currently running Smartermail 9,x on Windows 2008 Server.
 
I have been having a lot of problems with Email being rejected that my customers are sending out on different businesses, domains and accounts. I have them sending me the rejection and they don't really provide any real detail as to why it was rejected. I checked mxtoolbox for blacklisting and I was listed on Sorbs, Protected Sky and Spamhaus this past Friday and I requested to be removed. Now when I go to mxtoolbox.com and check all my IP's they come up clean. Can someone please give me a hand as to why these emails from multiple customers are being rejected?
 
Here is a copy of the rejected email and this is pretty standard for all emails that have been rejected:

DKIM, DMARC, rDNS, Feedback loops? There's a lot to be vetted in a situation like this, and it requires an in-depth analysis of every aspect of your server, the domain configuration, the sending domain's reputation, the reputation of the FQDN of you server, the IP address from which you are sending, etc.

Hello Bruce,

I've had this mail running fine for the last 10 years. I had your general hick-ups but over all never seen this kind of problem. I don't even know where to start!

Best thing to do is open a ticket or contact a tech to vet your server and domains completely.
 
I suspect this might take a couple of hours - depending on the number of domains you host and other aspects of your server's configuration.

Maybe too late now... but do you know WHY you were on those back-list to start with ??   Was as a spammer or ????
All things being equal, as far as your "server/email settings" ... would have to be some one or something is going through your server and sending huge amounts of emails....   Increase in volume...  on a domain??
- that is where i start... I am sure you have done all of things... but I always look as to why I on their list, and then work backwards... as you say = its a pain when your back is against the wall

Yes someone compromised a word press account and spammed off of the contact us form. By time I figured it out it was to late. I think I figured it out. It appears that I am being rejected because when my customers would email out of Outlook from there local PC such as comcast then receiving servers would reject me because the comcast ip was blacklisted even tho my servers ip's are fine.

For temporarily solution, you may change your customer outbound IP to another Public IP as you can sending out the email message.
