E-mail domain blacklisted

You need to check if your email domain allows relaying (this will cause issues) and if users (or just you) on your email domain has a virus that is sending out spam. You need to be certain your emails to clients are professional as badly formed marketing emails will appear to be spam.

Check all these things out and be sure you have cleaned everything up and then apply to the sites that have blacklisted you to be removed. This is harder rather than easier.

John is absolutely right. This is the right way to fix this issue permanently.

Oh, thanks John Jyiesla,

There are only 2 users on the email domain however, I will ask my host provider if there is any relaying?

Could this issue have risen due to the type host provider too?

Thanks all...

Could this issue have risen due to the type host provider too?

Yes. The host provider could have purchased / acquired IP ranges for their business that had been previously blacklisted. Such happened to me some years back and the Host provider corrected the issue.

Also make sure your marketing emails are well formed and have WORKING unsubscribe mechanisms.

Yes, we got caught when we got an email virus inside out network. I squashed it quickly, but apparently we sent out enough infected emails that a couple of the RBL listers blacklisted us.  It just so happened that one of the companies we do business with a lot subscribe to one of those lists.  I had to contact each list - I think we were on three - and ask that our name be removed.  They did so, but I was warned that they would check in 30 days to make sure we still were't doing the bad things. Your ISP may be able to help, but most likely you'll have to contact the list owners.

Thanks John,

Do you think having SPF system enabled would help bypass the issue or may be I should just change my host provider?

SPF might help and so it is worth a try. I would try this before changing providers, but do not rule out changing providers.

SPF records will not stop spammers. The SPF (Sender Policy Framework) allows other mail servers on the internet to send mail on your behalf using your domain. They can only send not receive. You would only add mail servers to your SPF record that you trust.

Hi Will,

I did a quick check on mxtoolbox.com and it shows everything as OK but checking on Blacklistalert.org is where I am getting the above error list.

I am a little bit confused as to what to do because my Host Provider are not able to help.

I guess it's time to change provider then.

When you talk to your hosting provider make sure that they have your reverse IP pointing to your mail.domain.com. If this is not done you can expect to be blacklisted.

A good test would be to do the following..
- open a command prompt
- type: nslookup <press enter>
- type: set type=MX <press enter>
- type: domain.com
*this will provide you with the MX records that are associated with the domain.com you referenced
Usually something like mail1.domain.com and mail2.domain.com etc

Keep the command prompt open.
Once you have this info do the following...
- type: set type=ptr
- type: <ip of your MX record> <press enter>

When you do this the IP should match up with mail.domain.com. If it does not then you have a reverse DNS mismatch and this would be the reason why you are getting spam blocked.

Will.
