Mails Bouncing Back With Error Number 450

Oct 8, 2009

I am facing a problem with my mails. I have hosted a new domain on my server and that domain is getting a lot of bounce messages with the following error message:

Message is waiting at <Mail server name> for delivery to <recipients SMTP>.

Message delivery has been delayed to the following recipients:
Recipient: [SMTP:<recepients email id>]
Reason: Remote SMTP Server Returned: 450 <Senders email id>: Sender address rejected: Domain not found

Also when I try to check the DNS settings of that domain from network-tools.com I get the error message as:

Retrieving DNS records for <domain name>...

DNS servers
nameserver1 [xxx.xxx.xxx.xxx]
nameserver2 [xxx.xxx.xxx.xxx]
Query for DNS records for <Domian name> failed: Timed out

The hosting server is configured on the following softwares:
Plesk 8.4 control panel
Bind DNS
Mail Enable Mail server

Hotmail And Yahoo Users Not Receiving Mails From My Site

Dec 7, 2007

Gmail users are fine.

Two days ago, Yahoo and hotmail users were receiving emails in the Junk folder. I thought this was due to the Reverse DNS settings not being set. So, I contacted Rus from cheapVPS and asked him to enable the Reverse DNS setting after I entered it in the Hyper VM panel, and he kindly did it.

Unfortunately, since the Reverse DNS setting was entered, Yahoo and Hotmail users stopped receiving mails from my site. Gmail users never faced any problem.
the logs (from maillog) are as follows:

VB Forums On VPS Hosts

Jun 18, 2009

I run a small vb forum that is quickly expanding beyond the shared hosting plan we currently have with GoDaddy. So far we have been looking at VPS as a solution that would allow us to grow as we grow.

I hope I'm allowed to ask this, but I am looking for examples of vb forums that have about 100 concurrently logged in members and examples of vb forums with 200 members concurrently logged in and are running on either KnownHost or WiredTree (or an alternative service).

Please provide a link to your forum, the name of the host, and the VPS package you currently have. Finally, please let me know if you are utilizing Litespeed.

I'm hoping this will become a great resource for growing community owners looking to take the next step.

Hosting Forums

Jun 22, 2008

Over the past 4 years I have had 5 different hosting companies. I run a small forum (400 to 1k page vies per day) and is a nuke forum. It usually runs flawlessly on the new host for 7 to 9 months and then the db bogs down and I switch to a new host and install the complete db again to the days postings and it runs gr8 yet again.

Im no expert but Im no newb either. I have worked for 2 hosting companies (Hostgator & Applied Innovations) and I have my Bachelors in IT. I know enough to be dangerous! Is there anyone who can tell me if there is a host that I can put my little forums on that doesnt charge an arm and a leg and is reliable enough to stay with.

I have seen all the reviews all over the place, but from working at hostgator I know they have their level 2 support people logging in to these types of forums as different people and posting great reviews every day, I dont think they have stopped doing that.

Is there any one who has been with their hosting co for years and have a site like mine that can say that they recommend it?

Emails Seem To Be Bouncing Back

Feb 25, 2009

The issue is that a lot of my emails seem to be bouncing back at the moment with the subject 'Subject: Warning: could not send message for past 1 day'

Could anyone explain why this might be the case? I've had a look online and the only thing I can think it might be is that my email address has been gray listed. To solve this it was recommended to use a SPF Record.

I did not really want to start messing around with my DNS before I could get some confirmation that this is the case. Though if there is another explaination please can you let m know.

The emails that I have sent have all had pdf's attached to them.

HowTo - Bouncing Of Dedicated

Jun 13, 2007

I'm on CentOS 4.4, webmin, LAMP, OpenSSH and ProFTPD server.

But what I'm wondering is how to look at my off network backup space.

I can only access my backup space through the DC network/my own server. So I need some kind of way to bounce a GUI ftp connection off the server - which would allow me to look at the files...

I know I can use rsync for backing up and restoring. But the way I understand rsync I need to know exactly what I am to move, as it operates on an exact command.

Are There Issues With Mod_Security And Forums

Aug 13, 2008

I am running Apache 2.2 on CentOS. I really want to install mod_security to lock things down. But I saw where there were some issues with mod_security and forums. I plan on having a forum live on my site shortly. I found this bit of info:

If you install mod security on the server, some forums will not work properly as this will compare each pattern which is posted against the rule set and will block it if found matching.

Is anyone using mod_security with a forum currently?

Can I Host My Forums On Different Server

Aug 29, 2008

I want to know that my main site smsbucket.com and smsbucket.com/forums are both hosted on same server.

But in future when my forum will grow I will need to switch host because my current hosting provider doesn't provide big disk space so in future can I just host /forums on different server? and keep smsbucket.com on my current server?

Server Bouncing Emails To Hotmail, MSN And Others

Aug 6, 2007

I have one of our servers that is bouncing all sent emails to hotmail, MSN and some others. The emails often come back saying they are bounced as SPAM.

There were SPAM issues on this particular server at one point, but have since been corrected one we tightened it up.

Now, how can I fix this? Can I change the servers hostname? Are they rejecting by hostname, or by IP?

And do I need to just contact each provider and try to get off their blacklist?

Preventing Users From Connecting To Other Users Database

Mar 25, 2009

On my server, users can connect to any database as long as they have the database user and password. This makes it easier to hack any database on the server.
What I want to do is to make the users can only connect to their own databases and not other's.

I tried changing the localhost ip address but it didn't work ( I assume I didn't do it the right way)

Staminus Communications Hosting Botnet Forums

Nov 7, 2009

Staminus Communications has been hosting a botnet forum, which distributes bots, worms, trojans, illegal clickers, and tons more, 95% of the site is illegal, and is forbidden by Staminus's provider yet they could care less as long as they get there money, I sent an abuse letter August 17th 2009, they even admitted things were illegal on the site, I pointed out several like the Google Adsense clicker bot which is highly illegal and which is nothing close to the other content hosted and/or linked to.

They are hosting unkn0wn.ws they refuse to remove the site or make them remove the illegal content which is most of the forum, which now forces me to send a letter to there provider and the cybercrime which I am now doing.

Now I guess they do not care about what they host, only if the person pays, so I guess I'm just going to expose it here for everyone to notice, because it's just going to get there data center raided over time by hosting illegal content and not removing it.

Let's see what you guys think, or what the admins have to say when they read this post.

What do you guys think when a provider does nothing about illegal content do you think it's the employee's that are at fault or the customer?

Forums Outgrowing Shared Hosting Plan Already

Jan 7, 2009

I have spent several hours on this forum over the past few days doing some research and have officially confused myself. I am a volunteer with a nonprofit organization and our online forums (running on vbulletin) are maxing out the database SQL connections several times per day. The host has a max_user_connections limit of 15 but doesn't have an intermediary step from shared hosting to dedicated hosting. Dedicated hosting is cost-prohibitive and the rest of our site has more than enough room to grow on our current hosting plan (including traffic bandwidth, disk space, etc).

We are planning to register a new domain name for the forums and move them off to another hosting provider. I donate the hosting fees to the organization and I don't have much of a budget to work with ($20/mo or so ideally). I am looking for recommendations for a hosting provider that will support a somewhat busy forum (usually only between 30-50 users online at once but anywhere between 1,000 and 2,500 pageviews per day) and also allow a stepped growth plan (instead of from shared straight to dedicated.)

I've seen Hawk Host, Siteground and URLJet mentioned frequently on posts here and over at vBulletin but I don't want to just jump into a new host and face a similar problem in the future.

Forwarding Email Account Dropping Emails Without Bouncing Them

Jun 20, 2009

I own my domain [url] and have a reseller plan on a shared host [url]I have the DNS on godaddy pointed to the nameservers of reyox and on the Cpanel of my domain at reyox I have a forwarding account [url]set to forward to my gmail account.

To the best of my knowledge this has worked flawlessly for years but recently I have been starting to not receive emails from people. I found out when I wasn't getting replies I had been expecting and when I inquired or called the people instead they told me that hey replied... it's been happening over and over again lately.

When I asked my host last week they replied: "We did clear up some mail issues last night, some issues with the queue processing."

However after that it kept happening and now I am at a loss.

I don't know what's wrong nor how to troubleshoot it... It happened with people that are on all sorts of domains (gmail, aol, personal domains etc) and it happens sporadically...
It's really frustrating because I don't know what else I am not getting considering that every other day I find out about an expected email I didn't get.

The werid thing is that none of the senders whose emails got lost reported that they received a bounce issue...

how I can address this in terms of troubleshooting it and finding a solution?

Is there some sort of email monitoring services like there are site uptime monitoring services?

Lunarpages Service Is Poor And They Censor All Criticism On Their Forums

Nov 24, 2006

I'll second what is said about Lunarpages. They are an absmal McHost whose priority is to lure in as many customers as possible without bothering about the quality of their service. I challenge anybody to ring their telephone support line and see if somebody picks it up. I have tried to call ten times in the last six months and never been able to get through once, despite hanging on for ages.

Just today my entire website was down because Lunarpages moved it to a new server (without asking me) and screwed up. The website, Azam.biz has over 17,000 references to it in Google and is critical to my business. I sat drowing in sweat for hours. I couldn't get hold of anybody at Lunarpages by telephone or live chat and the one support response I received ws addressing an unrelated issue.

Worse thing of the lot is Lunarpages censors criticism them on their forums more so than any webhost I have ever know. Every time I post a comment about downtime or not being able to get hold of anybody on the telephone, they delete the post saying it is "incorrect". I have never met a company with such a Stalinesque censorship policy.

I have feared posting anything negative about Lunarpages on other forums because I've been worried about them closing down my account. But, after having suffered so much stress because of them today, I don't care any more.

I am going to back up by entire site now, because I'm worried they will close down my account after reading this. They are not the type of company to take on board criticism and use it to improve their offerings; their obsession is to stifle any criticism.

I am now suffering pain in my heart for the first time in my life because of how badly Lunarpages have treated me today. Their arrogance shows no bounds - they are smug, full of hype and don't give a damn about ruining customers' businesses.

Plesk 11.x / Linux :: Mailbox Disabled - Email Accepted And Not Bouncing

Jul 4, 2014

I have Plesk 11.5.30 Update #47, Centos OS 6.5 x64, MTA Qmail 1.03

Today I encountered a estrange thing, a disabled mailbox was accepting mail but not bouncing it.

In the panel the "user@tld.com" mailbox is disabled, if a email is sent to that address Qmail accepts it:

Jul 4 17:51:35 mx3 qmail-queue-handlers[27432]: Handlers Filter before-queue for qmail started ...
Jul 4 17:51:36 mx3 qmail-queue-handlers[27432]: from=root@mx3
Jul 4 17:51:36 mx3 qmail-queue-handlers[27432]: to=user@tld.com
Jul 4 17:51:36 mx3 qmail-queue-handlers[27432]: handlers_stderr: SKIP

[Code] ....

No mail is bounced, nothing, the message is not in the mailbox.

Tested in several accounts the result is the same, even in a new created account.

Bought Private Domain Name Server (DNS) To Prevent Hotmail Bouncing...am I Wrong?

May 12, 2009

While I am used to reselling and domain registration stuff, I am totally new to DNS stuff..I tried many searches and readings without hope.
that's why I need your help.

We have a problem that makes both incoming and outgoing emails from our website's email server not going or received, without any failure message or error message on both sides: the sender and receiver.

We talked to our webhosting company- they do not own, but host on a dedicated provided by Iweb in Canada - and they told us a quick solution for this:

To buy a private IP address, therefore our websites with them will not get blocked as spammy IP, setting us away from the dozens of sites they have on the same server IP (as domaintools reverse IP reported: xx other sites hosted on this server).

The company I work for agreed on this solution immediately as we are loosing customers for this problem.

They charged us 8$ a month for this "private ip".

We had the same problem for another day after their solution, when I checked domaintools, I found our websites are still on the same IP of the company. I called them, and the Admin there told me: it's a hidden CNAME setting that is not shown to public because it's "private" and the delay happenned because we had to contact Hotmail staff and wait for their reply to include it in their safe list, but others as Gmail and Yahoo do not require contacting them and will go through automatically."

My question is:

- What is Private IP/ Private DNS?
- Why and how it is used to prevent false blocking/bouncing?
- Does that mean they had to sell it to every domain, while their IP is not on blacklists (I checked it).
- Is Private IP just an internal setting or it has to be bought from a large ISP
like regular/public IPs? and if just some settings, is this price fair? we pay 120$ annually for hosting one site with them.
- They told us they put our other two sites on theis same new private IP. How can this be possible?
- I cannot understand: Hotmail can prevent our emails from reaching inboxes, but can it also prevent its users emails from reaching us?? Is this issue a Private-IP related??
- What do you think the real problem is, and what advice(s) should I follow to have our emails going and coming smoothly in the future?

Note: We don't send unsolicited emails ever. We only have a 1500-member mailinglist that we send a newsletter to, once every few months.

Our daily email traffic is about 10 to 20 messages in and out.
