I've had problem with the VPS getting blacklisted alot lately.
Anyway, I think the problems resolved now and we've not been blacklisted for over 2 days, yet there still seems to be alot of e-mail servers rejecting mails from the server due to blacklisting.
I run a server and have ONLY problems if i am sending mails to domains hosted by google ...
OSUbuntu 12.04.5 LTS
Plesk version12.0.18 Update #24, last updated at Nov 20, 2014 06:32 AM
Here a little bit about my configuration:
a) I have set a Reverse DNS (xyz.mydomain1.com) - My hostname!
b) i run 4 domains on this server (mydomain1, mydomain2, mydomain3, mydomain4)
c) my DNS settings are made by myself in my Domain Provider account
d) i also set SPF records and i use Domain Keys
Everything works like a charm but following now the outputs with my problems:
Here is my postconf -n output:
Code:
root@shamu:/etc/postfix# postconf -n
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases, hash:/var/spool/postfix/plesk/aliases
append_dot_mydomain = no
[Code] ....
Now I sending a email from my domain2.tld and google rejects this email ...
We will shortly moving from our Shared to Dedicated hosting (First time). The main reason being the outgoing mails..
We need to send around 60k emails to our members/week (newsletter).
Our hosting company allowed only 200 mails per hour.. thus getting sick of this .. we decided to get our own server.
Now i have read many threads saying that they get blacklisted and their account being suspended..
How do i ensure that i don't land up being BLACKLISTED?
I ordered a server on Sagonet, a company specializing in renting dedicated servers. Well, after paying 125 euros, I receive a server with dns almost totally blacklisted in my country, Italy. I ask those of Sagonet of risolvermi the problem but they are slow and rude and say that I hosted illegal content on my server. Too bad that my server has only a forum half-empty and no illegal content and they want from me other $60 for control my sites, blackmailing me. So I paid for a service, without being able to take advantage and they . Be careful to Sagonet, a disservice, because people rude and incompetent.
View 14 Replies View RelatedI found out today hostgator.com is black listed and so is the ip they have given me for my domain. I have allways been a happy hostgator.com customer but when your domain is blacklisted because of your hosting company thats not good. It also prevents some people from being able to send you e-mail.
When I talked with HG support today they suggested a dedicated IP but no promises. So thats not a positive indicator as well.
I have the baby croc plan with them and would like something simular with another hosting company that I can be for sure is not on a black list. I have had no compliants with them over last 2 years I have used them but this is something that will make me leave them if there is nothing they can do to solve it which appears to be the case after speaking with HGs support.
My server seems to be caught under this listing, even though my IP address is not meantioned anywhere in the listing (nor have i been sending out any spam) The blacklist if of a netblock of 4096 ip address in which 2 of which belong to my server.

My question is really what do i do now?
Should I contact my provider or do I have to contact the spamhaus directly?
Searching G, I find these for running checks on blacklisted ips:
http://whatismyipaddress.com/staticp...ss-blacklisted
http://www.mxtoolbox.com/blacklists.aspx
Which both seem to be for blacklisted email servers. But what about checking if the ip has been blacklisted for other reasons ( business practices, reports of complaint, adult sites, etc)
What is a decent check?
This is for checking on newly assigned dedicated ip's ( or other) before applying them to domains on a new account.
we got a server blacklisted because there was a script sending spam emails, ofcourse we got that removed and taken more measures, the problem is that many lists still have our ips blacklisted (4 days after the solution was given).
is there some kind of script or any service/website that can check my server's ips for being in any spam list and notify me everyday ?
We have a few customers who have multiple C classes with us and we are wondering how most of you monitor for blacklisting.
We currently randomly pick a few IPS and check them once a month but this is not very thorough. We were wondering if there is a program out there that can check say a /20 automatically once a month or atleast something we can initiate an automated check once a month with?
I'm having a problem with a client (X) which doesn't receive emails from one of his clients(Y). After few days of talking with Y hosting company I wasn't able to solve the broblem, but told from them to check if their IP is blocked in my server (which I'm sure it isn't).
My first question is where to check for blacklisted IP which blocks email, and not HTTP request ...
Is there a different place than /etc/apf/deny_hosts.rules .. is there a file in exim configuration ?
I have a linux server with WHM 11.24.2.
----
The error that Y client receives when sending mail to X is:
Server Response: '550 5.0.0 <mail@mail.com>... User unknown', Port:
25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79
I'm very sure that if Y's IP was blocked he shouldn't receive that error.
What I belive is that there are some DNS problems, because X client was hosted on the same company as Y, now few years ago, and I belive that when moving X to my server, the other hosting company didn't deleted all DNS records .. and that's why Y clients get the error user unknown. Is it correct what I'm suppose ?
We are starting to send our newsletter out to people who subscribe to it. We are using the same server our website is on, so we have the same ip address. We don't spam or anything like that, but what if someone wants to report you. Do you get blacklisted right away or does it take multiple reportings? Does it mess up your search engine ranking?
View 2 Replies View RelatedOne of our customers has reporting not being able to access any sites hosted on our server. He is using a cable connection with a static IP number . He is able to access all other web sites on the Internet, he just can't access the ones hosted on our network.
Do you have any ideas on why this could be occuring, or if there is something on the server which could have blacklisted his static IP, preventing him access.
All emails sent from my server go direct to Bulk or Spam folder,how can i remove blacklisted status?
View 6 Replies View Relatedthe smtp server have ptr/a records setup, smtp auth enabled, isn't on any blacklist and never was. when sending mails to certain recipients mail returns with 554 error stating the ip is blacklisted. the referencing ip is dynamic ip used by sender, not the server itself. i inspected the headers and server ip is listed in one of the from fields, the client ip is listed under another from fields.
how do i prevent this error from happening? i don't want to relay my smtp server which is perfectly fine to isp smtp server. why isn't the receiving smtp checking the last from field which is server's ip but instead bounce the message because the client is on dynamic ip?
if you have any solution, please share, regardless of the mta you're using. i'll make the appropriate changes in my configuration. i'm thinking it's not my fault but receiving smtp fault because i can send using the same configuration to some other recipients who have spamhaus checking enabled and everything works fine because the server checks on the my server ip and not on the client's ip.

I turned off Sender Verification while Sender Verification Callouts was already unticked, yet I still get the same error even with this in the ACL config:

I have contacted hotmail asking why automated emails such as registration verification are being blocked and they said that my server's IP was on a blacklist for spam. I never spam and I do not think a bot has phished using my server's IP. Anyway, if I were to switch server IPs would that solve the problem?
View 5 Replies View RelatedThis is in regard to ongoing stress I've had over this server from DN...
Keep in mind this is a NEW server order; my first with this company.
I was assigned IPs that appear to be on multiple spam block lists. The "biggest" problems are mail being dumped to bulk by yahoo and dumped to bulk or completely black holed by hotmail. It was also blocked by comcast, mail.ru, and anyone who uses SORBS (those are the only ones I KNOW about so far). This helps reinforce the suspicion that bulk mail was being delivered from the IPs at some point.
I Contacted support at 9PM on the 13th and was referred to abuse. Only after complaining again on the 17th, was I told they requested removal from ONE of the blacklists and they would "look into" the others. I replied saying I wanted new IPs or I would request a refund and that I did not feel the service I recently purchased was actually delivered.
Now here is the part that is giving me the feeling this will not end well for me; I no longer see the abuse department ticket when I log into their ticket system.
What If I ordered the server to use as a mail server? Am I out of line for finding a new server unable to deliver mail to the hotmail/yahoo inbox unacceptable?
Telling my customers to wait and maybe someday their mail will be delivered to the major free mail services is not the kind of reputation I want to have. Its feels like I was sold a problem someone else created and am expected to wait an unspecified amount of time to see if it can be resolved. I do not feel its fair to be left hanging while waiting for white listing attempts on IPs I did not soil in the first place.
I really hate bulk mailers and spammers. : /
Scenario:
Client has a nice website with a "contact us" online form. The form itself is secure (no injection attacks etc) and simply collects some data from the site-user, and emails that data to the site owners email address.
This email is sent using php "FROM" the siteusers email address (eg: random@gmail.com etc), so that when it arrives with the site owner, they can simply hit reply etc.
However - the site owners email is protected by "FrontBridge" (aka Microsoft), and suddenly they stop receiving such form-mail.
Response from FrontBridge is
"If the IP that is sending these emails does not have the domain names that it is sending on behalf of registered to it, it can not send to our domain as it will be picked up and flagged as spam. " They then indicate that too much of this so called "spam" will result in a blacklisting - which is what seems to have now happenned.
Pretty unfair I'd have thought, and probably how MOST web based form2email scripts are setup.
We have a dedicated server running WHM/cPanel. Last week this server (which is in a data center, outside our office) started rejecting SMTP connections from computers outside our office, but allowing connections from our office. We do not have a firewall in place. The message returned from Thunderbird when attempting to connect from outside our office via SMTP was a generic "10060" error.
I did notice that if you go into the config on Thunderbird on a computer outside our office and set it to connect using SSL, it then works just fine. I'm finding this baffling and the logs that I see aren't showing any odd activity or providing a reason for the refusal of the connection.
I also don't understand why it accepts connections from our office, as I would have never changed anything to make it accept only from our office, as we connect from home and other locations as well.
I have DenyHosts to ban an IP after 5 failed ssh logins, and send me an e-mail when it happens. Ordinarily I average around 3 banned hosts a week.
I've gotten ten today. Four of them happened with a couple minutes of each other.
I'm just wondering if this is widespread, as if something new was just unleashed? Or is it just dumb (un)luck? I'm not really concerned; every account has a strong password.
I'm merely curious about whether or not other people have seen a surge in brute-force attempts?
(This machine is just hosting a couple of my sites, which get almost no hits... It's not as if people are specifically targeting me. It's just them guessing "alice" and "bob" type usernames.)
I have a customer who is trying to send email to an email direction but it bounces back with an error like this:
SMTP error from remote mail server after RCPT TO:<bancaweb@credicoop.com.ar>:
host sas.credicoop.com.ar [200.47.24.10]: 450 4.7.1 Client host rejected:
cannot find your hostname, [64.76.xxx.xxx]: retry timeout exceeded
I know it has something about a reversal dns but how do i fix it?
Have a new VPS, changed DNS and all is resolving fine. Check MX recods and again all is well. I can SEND email fine, and it is delivered, but ALL email sent to my VPS with LiquidWed is being rejected.
I checked the mail statistics page in WHM and sure enough there are nearly 300 rejected messages including benign stuff like gmail and monster.com (I had to do an arin lookup to see whom the IP's belonged to)
Any suggestions on how I can fix? I searched before starting the thread and found:

But the OP in that thread said the advice didn't work.
After upgrading to Plesk 12, I switched on email sending limit to 50 emails per hour per account and also changed mail config to start using domain names in SMTP and less than 12 hours later became blacklisted by CBL - hotmail and live rely on this blacklist - ; the argument was we were sending bots and malware. This server has been under ASL since over a year now and we are positive its clean; still we did a full scan and nothing came up and none of the mail accounts were even close to sending 50 emails per hour. Being sure we were not sending spam nor malware contacted CBL and got whitelisted ..... for less than 24 hours. This happened three days in a row until we switched back to the previous mail settings where domains are not used in SMTP greeting and since then, we haven't had any trouble with CBL. how can we prevent being blacklisted while using domain names in SMTP greetings?
