Gmail has blacklisted our domain

meshoxford used Ask the Experts™
Hi experts,

Gmail has blacklisted us because we had an email that was compromised but the problem has been resolved. We had this issue with almost every ISP or mail service... all of them have been resolved except gmail.

I have followed the link below but after giving them my mail server IP it just says to wait a short period of time but it has been 5 business days without any spam being sent.... is there anything else I can do? Or do I just need to wait a few weeks because that is google's policy?

Heres the bounceback email

IP address is blocked not the domain.

From your source server multiple mails are being sent.

you need to find out what is sending emails out first because there's no point requesting de-listing if you gonna get listed again.

then after you have found culprit >>

will help you de-list off gmail.
Make sure that your email server is not an open relay for spammers to use:

You might have an open relay.  The link I previously posted is not working at the moment.

I plugged your IP address into, and you had failures.


Yes our email servier is blocked...

change the ip address, call your service provider

but first find the problem and fix it. in the meantime, you can use online webmail


sorry I did not see some of the responses... I just checked and it shows that we are not an open relay.

Although on I did have failures. The email account that was spamming has been deleted. So we know the problem is fixed. I have checked out mail queue and there is no more spam going out or attempting to go out.

I will see if they can change our MS IP.

@ innocentdevil... I will try you link next.



Ive followed everything that has been posted prior... gmail just wont whitelist us... I need to talk to someone at google on the phone... I do not know what else to do.
google is VERY slow at doing things

if you need immediate relief, the only way is to change your IP
I doubt Google will white list you.  If you were on a white list and then your email server started spamming, it would not look good for Google.  Changing your IP address should only be a last-resort measure.  Give it time.  You could also have your email send through an external relay - if you had another site you could set up an SMTP server to accept email only from your blacklisted IP address, then forward your email to the Internet.

Similarly to forwarding through one of your own external relays, you could subscribe to email filtering services such as Forefront Online Protection for Exchange, where all your email gets sent to their servers before hitting their ultimate destinations.  Also, your inbound email is filtered for spam before hitting your network.  Rarely do these reputable companies get blacklisted, and when they do the problem is quickly corrected.


Thanks a lot! this was the information that I was looking for.
