Emails Blocked From ISP

Oct 13, 2009

I have recently switched to GreenGeeks, great company and great support, but I am having a huge problem that all my clients and I are having problems with. No one can send emails to ATT, Verizon, Earthlink, Comcast, Etc. because they bounce back as being blocked. I have contacted them to unblock the IP and they do, but then a few days pass and it's blocked again. WTH? I've contacted GreenGeeks and they are aware of the problem but I really need to move on with this problem, does anyone know of any solution to do?

Emails Getting Blocked By Comcast/Trend Micro

Apr 15, 2009

I've recently gotten a new dedicated server and am in a bit of a bind because all emails to Comcast are blocked. I have verified that the IP is not on any RBL I can find but it does appear on the Trend Micro DUL list. This is a list that appears to not be maintained but which the wingnuts at Comcast are using. Emails to the maintainer of the list or to Comcast are auto-responded to and promptly ignored.

I'm at wits end (admittedly, not a long journey) with this. As a small provider I guess I just don't count but it is annoying as hell that there is no way to get these folks to listen. Every legitimate RBL on the planet has someone to help with issues but Trend Micro appears to not. And Comcast doesn't care about their customers getting legitimate email. Actually, I guess they just don't care period.

Has anyone else experienced this and, if so, were you able to figure out what magical incantation it takes to get through to a human who cares?

Plesk 12.x / Linux :: See And Release Emails Blocked By Outgoing Mail Control

Jan 10, 2015

Is it possible to see what e-mails are blocked/prohibited by Plesk Outgoing mail control? Currently i've set a limit of 20 mails on each mailbox. Yesterday I received an e-mail that there were messages blocked. For me personally it would be good to see what the receivers email adresses are and optionally what the content of the e-mail was. This way I can find out if it was really spam or not.

If the e-mails weren't spam, is there a possibility to release and send them?

Thousands Of Emails Being Sent Via Sendmail To Ne.jp Emails

Sep 4, 2007

Since Jan 07, one of our servers has been sending thousands of emails to ne.jp hosts.

Eg from logs:

Code:

We're absolutely unable to track or find out who is sending it or how to stop this.

So I'm wondering if it is possible to prevent sendmail from sending to:

lsean.ezweb.ne.jp, OR
docomo.ne.jp, OR
softbank.ne.jp

IP Blocked

Jan 20, 2008

All of a sudden my sites are not visible to me hosted in the same cirtex hosting account. I have verified that it wasn't spyware messing with my local computer and can view the site via a proxy. They use cpanel and there is no block visible, but there has to be something somehwere. I told them to restart and that did make the site visible until I checked in the morning, Where would a block be if this is it and is there a chance this was done by a hacker?

Blocked By MSN

Jul 19, 2007

I am blocked by MSN. All email messages directed to any @hotmail.com address is rejected, here a typical message:

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

name@hotmail.com
SMTP error from remote mail server after MAIL FROM:<user@mydomain.com> SIZE=1802:

I have never spammed nor sent similar content as that listed above.

My host provider says they are contacting MSN for an explantion, but time is running and I need to find a solution to this, because I have some customers (hosted in my server) which need to answer to @hotmailers prospects on their product/services.

IP Not Being Blocked Properly

Jun 28, 2009

I need to block a specific IP:
93.6.224.242

It adds fine when I do:
iptables -A INPUT -s 93.6.224.242 -j DROP

However, the IP is still accessing files and pages on the site according to Apache:

When I ban other IP's they are blocked from accessing anything on the server (e.g. it wouldn't even reach Apache level because of firewall), but this IP just isn't banning properly.

SYNFLOOD Blocked

Feb 20, 2008

Recently switched firewalls from APF and CSF, and so far couldn't be happier! But I do have some questions on SYNFLOOD_RATE within CSF.

Currently have a setting for "40/s" and I am still getting many messages in /var/log/messages with *SYNFLOOD Blocked*.

If I enable Synflood checking, the load on the server increases, but the bandwidth usage decreases. But I'm wondering if 'good' visitors are getting turned away?

Is the setting meaning block above 40/s per IP?

Or simply block above 40/s?

Also, does the firewall simply drop the packets above 40?

And is the IP Blocked?

Port 110 Blocked

Nov 16, 2008

They started blocking my Port 25, so I made an iptables entry on my server to redirect posrt 26 to port 25 so I could set my outgoing mail for my server (from Outlook) to port 26. But one day later teh bastards are blocking my port 26 too! Guess they just don't want ANY outbound mail send from anything but their servers! If I had any other option, I'd dump Comcast in a heartbeat!

Blocked URLs

May 4, 2008

I'm testing scripts on new server now, and server has 2 problems.

1. I can not enter domain name as "get" parameter. For example, if I'm requesting URL like domain.com/file.php?url=[url] - it does not work. If I'm requesting URL like domain.com/file.php?url=[url](please note it has INVALID extension for TLD) - it works!

2. fsockopen and file_get_contents does not work. I added these settings into php.ini:

allow_url_fopen = On
allow_url_include = On

...and nothing works. I get just blank pages when using these functions.

Server is running cpanel + apache 2.2 + php 5 + APF firewall

IP Blocked By Spamhaus

Aug 12, 2007

I've just got a fully manage VPS, unfortunately the newly aquired IP was listed in PBL (policy Block List)by spamhaus which is a nonspam source. I've got the ip de-listed but apparently some servers are still rejecting emails coming from this IP. It have been almost 48 hrs. Question is:

1) How can the IP got listed when it's never been use? How can we check IP is indeed a 'fresh' or pr-owned by spammers?

2) What is the possibility of the IP being blacklisted by these servers forever? How long does it normally take for it to be totally in the clear?

3) What are the preventive measures that can avoid IP being listed?

4) Is configuring Reverse DNS PTR a standard procedure in server set-up and could missing that config be the main reason the IP got tagged?

Email Getting Blocked

Feb 22, 2007

I have a leased server that I use cpanel and webhost manager to manage. I've just set up the server in the past week and put our website on it and created all the email accounts. The emails are all working fine now, but we have another website on someone elses server that has sends an email (using php) and the emails aren't going through.

They went through just fine before I moved our site and email accounts over, and I've checked in cpanel to see if I had any spam filters turned on and I don't. I've also tried sending email manually using thunderbird and outlook, both work fine. Also, on our server, i've been able to send email through php.

Anyone know of a setting that I might be missing in my webhost manager?

Jun 5, 2007

I am often blocked by my own server.

So I can access my site through anonymouser.com but I cannot access my site directly. Changing my IP (using ASDL) will solve the problem.

A techie told me that it happened because of failed login attempt.

However, I had not made any failed login attempt?

Then it happened again today.

Why is this happening?

Though I didn't make eronous login attempt, I did try to check whether my sites are on or not a lot.
