Relaying Denied. IP Name Lookup Failed [xx.xxx.xx.xxx]
Nov 17, 2006
My VPS Config:
centos with webmin
mail program sendmail
Its a newly configured VPS have a problem with smtp realying through outlook and other smtp programs. When i use smtp on outlook it give following error:
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'xxxxx@yahoo.com'. Subject 'Outlook', Account: 'Testing', Server: 'xxxx.com', Protocol: SMTP, Server Response: '550 5.7.1 <xxxxx@yahoo.com>... Relaying denied. IP name possibly forged [xx.xxx.xx.xxx]', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79
I want to make outgoing authentication activate instead of allowing some iprange or domain for relaying through /etc/mail/access.
I can't figure out how to be able to send mails using sendmail. I've a dovecot/sendmail installation and I can recieve mails OK but when I try to send mail I get the error message "Relaying denied. Proper authentication required."
Example from maillog: Oct 2 18:10:08 localhost sendmail[2196]: l92GA4UC002196: ruleset=check_rcpt, arg1=<xxxxx@gmail.com>, relay=rl-nvt-kaxx.xxxxxx.xxx [000.000.000.000] ....

We have a little issue with the API, when we want to add an subscription, then we became "Error: Permission denied. (1006)" - but the subscription was added. The status Icon of the Subscription is a "!" and they say (tooltip), that the Plan wasn't correctly synchronized, but we don't use a Plan for this. The Reseller has all rights, there are now limits.
I don't know when we had this problem the first time, but i know that if had worked in Plesk 12 correctly - i think the problem came up with the last 4 - 6 MU.
We actually have Plesk 12.0.18 Update #16 and running it on Debian 6.0.9.
Recently we had to rollback the Plesk database and Plesk version files to their pre-upgrade state, and rerun the upgrade procedure as it is described in the knowledge base [URL] ..... The update process then worked smoothly and we are now using the newest version 12.0.18 on CentOS 6 with the newest microupdates 1200150615.10.
But right after this update procedure we are not able to access some domains with the filemanager anymore. The browser shows the following error message:
Internal error: filemng: opendir failed: Permission denied System error 13: Permission denied Message filemng: opendir failed: Permission denied System error 13: Permission denied File Agent.php Line 243 Type PleskUtilExceptio
The logfile: /usr/local/psa/admin/logs/panel.log is a bit more detailed
[URL] ....
What I did so far was the following:
1.) I checked out the knowledge base, specifically this entry was worth looking at. But /usr/local/psa/bin/repair --restore-vhosts-permissions didn't solve the problem. 2.) I found a similar problem in the discussion board but the approaches they took weren't successful in my case.
Due to the fact that the file manager worked before the rollback of the database and the major upgrade, I think there might be a connection.
From my point of view the permission settings should be right. Other domains using exactly the same permissions and they are working fine.

I have set up my Virtual Private Server and uploaded all my site's files to /var/www folder. Before that, there was an old simple 'index.html' file
Code: <html> <head> <title>INDEX</title> </head> <body> <h1>IT WORKS!!!!</h1> </body> </html> and when I typed the address www.mydomain.com it displayed correctly. Then I deleted this html and uploaded my files through FTP and now the browser says :
Code: Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0
Fatal error: Unknown: Failed opening required '/var/www/index.php' (include_path='.:/usr/share/php:/usr/share/pear') in Unknown on line 0
One of my clients has a couple of servers from me.
In the course of my work, I've setup various people to send mail via one of these servers, using SMTP on port 587.
Can I see on the server who has been using it to send via port 587? I didn't keep a record, the server is closing down and I'd like to let as many people as possible know that they need to change their SMTP settings .. there are only 50 or so I think.
I have a domain that used to have a huge members list with thousands of email addresses. Now that I enabled its web site, the server attempts to relay email meant for those harvested addresses. Also, spam relayers picked up that the DNS is live and try to use the domain to deliver spam What can I do with the MX records in order to dump all email without the server handling it? Currently all email is set to :blackhole:
I've got a domain name ("problemdomain.com") on my server (CentOS 4, WHM/cPanel) that has been set up with Postini for quite some time. All has been working & routing correctly. I recently changed to a new server with a new IP address. I transferred the account so that the DNS is setup identically on the new server. The only thing that changed is the main server IP, and the IP addresses that ns1.myserver.com and ns2.myserver.com resolve to. That propagation went through today and should be well set in.
Now, whenever you send an email to someone on this domain, it gets bounced back with the following:
This is an automatically generated Delivery Status Notification
Delivery to the following recipient failed permanently:
mail@problemdomain.com
Technical details of permanent failure: PERM_FAILURE: SMTP Error (state 13): 550-exprod8mx214.postini.com (psmtp.com) [64.18.3.114] is currently not 550-permitted to relay through this server. Perhaps you have not logged into 550-the pop/imap server in the last 30 minutes or do not have SMTP 550 Authentication turned on in your email client.
The way I have the DNS setup on the server for the MX records is as follows: problemdomain.com., 14400, IN MX, 100, laserskinsurgery.com.s8a1.psmtp.com. problemdomain.com., 14400, IN MX, 200, laserskinsurgery.com.s8a2.psmtp.com. problemdomain.com., 14400, IN MX, 300, laserskinsurgery.com.s8b1.psmtp.com. problemdomain.com., 14400, IN MX, 400, laserskinsurgery.com.s8b2.psmtp.com.
This DNS is exactly the way it was setup before when it was working. Any ideas what could be causing this?
I have two domains that I recently "re-animated" and they are been used as spam relays. I get almost 2 connections per second, according to the exim log.
I use ConfigServer Security & Firewall http://www.configserver.com/cp/csf.html which can block IP's that exceed a number of SMTP connections per hour. But these are thousands of IPs and proxies. Is there anything else I can do?
I facing a serious problem with my qmail and plesk 11.0.9.I found the way spammer did with my server by listening everything on port 25. Maybe he know the RCPT hosts of mine, and they send emails with random username but with domain hosted on my Plesk. (user1@mydomain.com, user2@ my domain.com, ... userxxx@mydomain.com).
qmail only check domain in RCPT if spammer input:"mail from user1@mydomain.com" - (with out ":") - no email address on my server.then server reply: 550, no mailbox here by that name. (#5.7.17)
But qmail check username and domain if spammer input:""mail from: user1@mydomain.com" - (with ":") - no email address on my server. Then server reply: 250 OK..This is really weird! I tried with all my plesk server, this bug still effected.Click to expand...
if I do a reverse lookup on my server's IP it returns a host assigned by the data center. So is this something I should even be managing too or is that always left up to the DC? I run my own DNS for the forward lookup zones.
Also just a technical question, when you do a reverse lookup, how does it know where to look to get the host? I'm not sure I fully understand how these work.
Somebody purchased a domain from a popular registrar. When you lookup the domain, it points to its own name servers (i.e. ns1.registrar.com and ns2.registrar.com), which means that it is hosted by them as well. correct?
this person is saying they bought their domain from the registrar, but they are hosted by company X. he says that he is pointing the ip address of his web site on company X to his registrar.
I want to know how serious following nameserver problem can be in reality: [url] ?
From DNS timing someone could conclude it's a slow hosting.
Can anyone explain above results "accurately" ? I still don't know what's "good" result in DNS timing: A or F?
The problem is that [url] loads slow (5-10 seconds on T1 connection), here's a speed test. I'm aware images and scripts contribute to slow site loading.
My question is: Beside removing some images from the Home page, is it any reason to change the hosting (regarding DNS tests).
Friend of mine asked me what "CURL named lookup issue resolved" means, he's got a CentOS 4 machine, with cPanel/WHM latest builds I tried recompiling apache and even cPanel at some point but no good..
I am having a problem. My server was able to ping google.com successfully before installing DirectAdmin.
However after installing DirectAdmin, I am no longer able to ping google.com anymore. I just get a host cannot be found error. This is the same with all other domains.
The /etc/resolv.conf is exactly the same, so I do not know the issue. I also have other servers using the same nameserver and are still able to ping and resolve successfully.
The main problem here is that exim no longer can send email as it cannot lookup the hostnames.
the error from exim is: R=lookuphost defer (-1): host lookup did not complete.
I have six dedicated servers on a VPR. I use one of these as the Database server and the other five connects to that server to read the Database.
When I setup my scripts for the first time I used the external IP to connect to the DB server. Everything worked perfect for these weeks:
mysql_connect('174.xxx.xxx.xx', 'user', 'pass');
Since three days ago I finally received the internal IPs of my servers and now I use the internal IP of the DB server:
mysql_connect('10.0.0.1:3306', 'user', 'pass');
When I did this last change this my database started to collapse. Queries stuck on a bottleneck every 10 minutes. Here's an example:
40468 simon 10.0.0.7:47002 pkindigo_db Query 115 Locked update `captured` set hp_left = '79', status = 'normal', att1pp = '25', att2pp = '30', att3p 40523 simon 10.0.0.2:58080 pkindigo_db Query 115 Locked update `captured` set experience = '5120', level = '16', hp_left = '58', hp = '58', status = ... (tons of locked queries before) ...
As you may see table is locked since 115 seconds for a simple update... after some hours this ends on a "#1135 - Can't create a new thread (errno 13); if you are not out of available memory, you can consult the manual for a possible OS-dependent bug" and even some of my tables finally crashing.
I think that my Database stuck because of a DNS lookup delay. When I had this problem before using the external IPs, I added skip-name-resolve and the problem was fixed. But now with the internal IPs it seems that's not enough.
I'm having tons of problems trying to get reverse lookup working on my dns server. I've scoured the net and tried lots of methods but so far none work.
Forward lookup DNS is working perfect, but reverse lookup is completely broken.

if its possible to change the reverse lookup, or at least i think thats what it is called.
I have 2 accounts on my CentOS, WHM/cPanel VPS and they are hosted on their own seperate IPs however when you do a lookup on one domain it also lists the other domain as being hosted on the server and vice-versa.
How do i change this so they appear like they are on different servers? Each one has their own nameservers which are on seperate IPs also.
My MySQL server slowed down to a crawl a few days ago, and I finally fixed it by starting it without DNS lookups via "--skip-name-resolve".
I tested domain name resolution on the MySQL machine and it was able to return IPs from domains rather quickly, so I'm at a loss as to why DNS was the problem here? I am using "192.168.1.6" as the MySQL server's IP, in case that matters?
I have a couple of questions:Why is DNS resolution so slow when in the command line it's running normally?
Why does MySQL need to do DNS lookups at all? I don't see any log files that's converting IPs to host names or vice versa.
Where am I sending e-mails from with the below settings:
(Is it mail.freesexdoor.com, www.freesexdoor.com, 64.85.161.123 or 64.85.161.124?)
My secondary question is: Is creating own reverse IP lookup to 64.85.161.124 possible and beneficial in my case? If so, what should I replace this SPF line with: freesexdoor.com. TXT "v=spf1 a mx ip4:64.85.161.123 ?all"?
I'm trying to improve freesexdoor.com's e-mail delivery ratio because hotmail and gmail deliver my PHP mailer's sent confirmation e-mails to the junk folder. I've done everything I can to improve the sent headers etc. so there's only one more possible way to improve it: (That I can think of). Freesexdoor.com is hosted on the same server as mitorahgames.com.
DirectAdmin control panel on CentOS 4.4.
My server's primary IP is: 64.85.161.123 My server's hostname is: server.mitorahgames.com
server.mitorahgames.com's Related DNS Settings: mailA64.85.161.123 server.mitorahgames.com.A64.85.161.123 server.mitorahgames.com.NSns1.mitorahgames.com. server.mitorahgames.com.NSns2.mitorahgames.com. mailMX10 123.161.85.64.in-addr.arpaPTRserver.mitorahgames.com. server.mitorahgames.com.TXT"v=spf1 a mx ip4:64.85.161.123 ?all"
freesexdoor.com's IP is: 64.85.161.124 freesexdoor.com's Related DNS Settings:
freesexdoor.com.A64.85.161.124 mailA64.85.161.124 mailMX10 freesexdoor.com.TXT"v=spf1 a mx ip4:64.85.161.123 ?all"
I'm by the way putting www.freesexdoor.com (PHP reported server name) to the Message ID: field in the e-mail headers. Would putting IP there perhaps work better? If so, which IP?
I have a windows 2000 server and I would like to configure two domain names, c.com and bnvsaj.c.com and requests to these domains should be forwarded to 192.168.0.1 and 192.168.0.2. How can I configure like this?
One of my customers uses Webmasters Tools from google , looking at what pages he have indexed by Googlebot, found that 180 pages are giving a "DNS lookup timeout" error, tried searching for help on google and the only thing that i found is " We received a timeout on DNS lookup."
DNS are ok, same as the zone file, everything is responding OK, I dont know what can be the issue.. ? any ideas ?
I regularly have DNS issues with some of my sites hosted with a specific host... At random sites, the urls done resolve and I get a DNS error. Just to find out that a few hours later it loads again without issues...
I always thought it had something to do with my ISP... My host says that there's nothing wrong with their DNS. However, I asked a few people now and it seems they're having DNS problems too sometimes when accessing the problematic urls...
