I have had server IP's blacklisted by Microsoft a few times and I have had them removed reasonably quickly. I noticed that after entering and joining anti spam related services that they recommend it was faster and easier.
I recommend that you ensure that you can reply Yes to the below questions (except the last one) in the web form where you ask for ...
Hotmail, which is operated under Outlook.com now, is provided by Microsoft. You can request they remove your IP address by completing the form here (this may require signing up for Outlook.com first).
It will take a few days for them to investigate the report, and if your IP address was not associated with sending Spam, you'll receive an email back from ...

Checking RHSBL & LHSBL Blacklists
I'd recommend Blacklist Alert, Ultratools and Mxtoolbox which checks both RHSBL and LHSBL across various networks such as RFC-Ignorant, Anonwhois, dnsbl, spamhaus and dozens more.
Also worth checking out what trust and review sites say about the domain i.e these:
Norton Safe Web

I also had my website blocked by Websense, with the reason that is was categorized as "gambling". It's not a gambling site, but it does have social media widgets such as Facebook comments, share buttons, etc... and is built on WordPress.
I signed up for Websense to use the URL lookup tool but also got the: Sorry, you are unauthorized to access this page ...
This is a very old spam list. Read more about it here:
I would say the list is a valid spam list and you should manually request to get off the list after you fixed the problems that made you get on the list.
Go to the below URL and search on for your domain.
This will check a bunch of blacklists and it will tell you if your domain is listed. there is also advise on how to get removed.
You might be listed with more than just Microsoft.
Typically an organization like Spamhaus.org will maintain those kinds of lists. If you find out which organization blacklisted you, they are usually pretty good about getting you removed if you contact them.
You are/your server is not requesting any images. Your visitors are requesting them, via their browser, using their IP.
Therefore there will be no massiv download of images from your IP.
The only thing that could lead to blocking of your domain could be the referer. Each time a browser send a request to a server, in this case if it access
If you are using the free versions or lower plans of an e-mail provider, there is a chance that your e-mails will go to SPAM. This is because the IP used by the provider to send your e-mails have been shared with other free users who might have been marked by many people as Spam and that reputation is carry forwarded to you because of the same IP.
To tackle ...
The message you're seeing is in regards to The Spamhaus Project, which compiles and distributes lists of IP's and domains associated with email spam so that email servers can filter them out.
Unlike content-matching tools like SpamAssassin, which uses a variety of spam-detection techniques (including analyzing the content of the message), filtering based ...
Websense guidelines are here: http://www.websense.com/content/support/library/shared/sec_labs/social_web13/social_web.pdf
Read the above. If you have a wordpress.com account you will likely be blocked.
I personally use IP address blacklisting. It is a tool that is often effective at stopping abuse.
There is certainly a risk that IP addresses are shared. All AOL customers appear to come from a small set of IP addresses. Many office buildings use a single IP address for all workers in that building.
You should be able to look at your server logs to ...
The CBL blacklist is not an e-mail blacklist per se. It is used to indicate that a system is compromised, however, I fault the methodologies of how systems are detected and placed onto this blacklist. All that is required is legitimate functioning and a single access to the wrong place.
How this works is often really simple. Any IP/port access to a known ...
You have far less to worry about than you think. But there are things to look for.
All blacklists are based upon domainname.tld and/or IP address at it's base. In the case that you cited, example.com will not be blacklisted because example.net or example.de has become blacklisted unless they are related by ownership, registration, or host.
If example.com ...
In regard to your automated emails failing, these spammer email addresses used for the fake registrations often bounce because they either don't exist or quickly become full, or are flagged as spammer addresses - for this reason your server will have a high rate of bounced emails. This will affect the mail reputation of your server and will in turn degrade ...
Any website, or any server that sends a huge volume of emails runs the risk of their IP or domain being added to email blacklists. Also, similar, or exact emails are higher on the risk factor, especially when it comes to 'MASS' public email addresses such as:
You can find out if your server IP or domain has been ...
In Spam blacklisting , only the IP address is blacklisted and nor content of the website / app , this is mainly an issue in shared hosting servers where a single IP address is shared among different users. If 1 users on the network is sniffed by spam spiders "Spam Detection apps/websites" then all users on the network/shared host using the same IP suffer the ...
they have fabelsources registered with them under the list of blacklists to check for bad IP addresses. When an IP is blacklisted like this, it generally means the computer with the IP in question (which I will call, the machine from now on) is a source of sending spam.
For example, a program that continuously sends ...
Generally if your email is blacklisted there are 2 things you can do each time this happens.
It's temporarily black listed and will be lifted after about 24-48 hours (depends on black list) after the last spam was reported.
you contact the blacklist site and request they remove your email from their blacklist.
It is harder to figure out what blacklist the ...
The big question is if you have permission to query the said server? If so, you should ask them to check if it is blocked.
If you are getting partial data (not empty) the your IP is definitely not blocked. It could well be something to do with the connection to or from the server.
This message looks to me like it comes from Symantic's Web Gateway. Here is a page where somebody with the same error message points the finger at Symantec. Symantec has a URL filtering categories page that lists the category your website has been misassigned:

To state the obvious you can test if office 365 is blocking your emails by creating a 30 day trial.
If your emails are being blocked then you need to address the issue why, which is how they are getting marked as spam. There are plenty of questions related to preventing email being classified as spam already on Pro Webmasters. Then you would either need to ...
I realise that this is a 2015 question and that it has probably been resolved internally already but for others who encounter the same issue in the future...
Cox does reply back even if the decision is to not unblock. Sometimes unblocking can take a while to decide, especially if there has been a large number of unblock requests made at the same time by ...
Your domain is not necessarily being accused of e-mail spam. Here are the categories from their FAQ:

I would suggest checking your domain name and the IP address of your domain ...
Google doesn't make it very clear when they will or won't block IP's or emails but Google's policy is to automate everything as much as possible. This can create some problems sometimes. Awhile back google alerts was used for spam. https://robert.accettura.com/blog/2007/06/20/google-used-for-spam/ things like this happen from time to time. When it does, ...
The solution is: Fix the vulnerability (which you did), set up SPF and DKIM for the domain (which your admin probably did already), then request to get yourself off the blacklists. After that it will work.
You can use http://mxtoolbox.com/blacklists.aspx to check which blacklist(s) an IP is on, then email the list to request removal. It still takes less ...
The problem is that your blacklisted, and Mandrill won't want to send email for what they consider to be spammers.
As far as I can see, you have 2 options.
The first, obvious solution is to get yourself removed from all the blacklists that you can. In my experience this has usually taken less than 24 hours, but that was also years ago so could be longer.
Your problem is probably that because you are on an IP blacklist the mail that you are sending Mandril is never getting to them.
If I were you, I would look into the REST mandril API. They probably have a php client, and I remember a lot of examples on their website.
Here is a simplified diagram of how to message is sent

First of all, it may be worth paying Sucuri to get them to log into your server and do a more complete check for malicious code or backdoors installed. Their free check only finds malware that is actively attempting to infect visitors and reports blacklist status. Before any other steps can be taken you need to make sure your site and server are indeed ...
