Server :: Mail Server Blocks: Warning: Numeric Domain Name In Resource Data Of MX Record
Feb 4, 2010
My test messages from one mail server to another are getting sent to my spambucket and the only error in the logs is: warning: numeric domain name in resource data of MX record for [URL]: 74.63.64.42
There is an requirement, intranet people they may not have internet access but they want to send mail to external domain(internet),but in that intranet network one machine can have internet access. Is there any solution for this requirement.
I have a Slackware 12.1 box with mail server running on Postfix and Dovecot. My domain name is,say, [URL].. I have another domain, mail.xyz.net. I want to use both the domain for incoming. Like, someone sends mail to [URL]... otherone sends mail to user@xyz.net. Both the mail should be received.
I recently decided I wanted a web server so I installed Ubuntu and apache2 on it and it works fine. I installed forums on the site as well and it's working fine to. Problem I don't know exactly what to do with the site so I haven't purchased a domain yet (so to access the site you just type in the ip address).
I know this sounds really weird but I want to know if I can make a mail server without a domain name. I kinda want to use it for e-mail verification for the forum. I have been following this tutorial: [URL] and it seems i need a domain name. Is it possible? Also I am not using Ubuntu server, would setting up a mail server be much easier on there (or rather, does it come with a mail server?)
I m using sendmail-8.13.8-2.el5 along with MailScanner-4.79.11-1
i want to set a rule so that user1@mydomain.com can send only to anotherdomain.com domain. sending mail to any other domain will be rejected. can it be done by sendmail or MailScanner ??
I'm trying to set up an mail filter for our domain. At the moment we're using ClearOS as the filter, works OK but I still get something through and the blacklist and whitelist doesn't seem to work. I was hoping to set up a mail filter on my own, using Spamassassin and/or something else. It seems I have to buy subscription at ClearOS to make it update better or something. I might just do that, it's just tempting to find a way to do it on "my own". I tried to follow these instructions but I don't seem to go anywhere... ...I began with setting up the base server as it is shown there. I've setup quite a few Linux servers, mainly as firewall/gateway kind of things but also some DNS servers, web servers and so on.
I have one mail server and the mail filter is supposed to be on the outside to filter mail before it hits the mail server.
I have a CentOS 5.2 server with hostname support.companyname.local It's used to run Request Tracker 3.8.1. I need to be able to send email from this machine and make it look like the email came from user@companyname.com instead of user@support.companyname.local
Im trying to get postfix to filter my outgoing mail and basically drop everything that is not in my hash table.
So far I managed to get this going
Code:
Code:
Unfortunately those rules also apply to incoming messages. My goal is to disallow users on my host to change their "MAIL FROM" to anything they like and restrict them to domains I specify. I'm aware that the local part still is variable and a user of domain "foo.com" could use a email of domain "bar.com", but still some of my troubles would be solved if I get this running.
I'm using Ubuntu Server 10.04 and I can successfully relay mail generated by php scripts through an Exchange server.What I want to do is accept incoming mail from the Internet through postfix and relay it to the Exchange server but I want all mail that is not addressed to ...@mydomain.edu to be discarded.
I've got a home server running Ubuntu Server 9.04 and several machines running Ubuntu Desktop (9.04 and 8.04) and Windows (XP, Vista and 7). Now what I want to do is to create a domain and directory server similar in function to Windows Server w/ AD and join my other machines to the domain, but am not sure where to start. I already have file shares with Samba but now I want to setup a domain.
I was thinking about setting up my own mail server. Problem is my ISP will not let me have a static IP unless I upgrade to a Business class service which is just too expensive for home use. As a work around I use a DDNS service from Dlink, which is actually done via DYNDNS.com. So essentially I have mydomain.dlinkddns.com point to my Dynamic WAN IP, and it is all automatically managed by my router.
Is there a way I can haveoint to my mail server without it being a subdomain of my DDNS om)? In other words I would like to have the email someone@mymaildomain.com and not have it be dlinkddns.com or something like that. I know someone has done it, I just have never done it. Not quite sure what to google to find the answer myself either.
I am managing a Fedora dedicated server with Plesk 9 and just recently moved the email for one of the domains on the server to Google Apps for business. Unfortunately, I cannot get email messages from the website forms to deliver to addresses on this domain. For anyone familiar with Plesk, I have disabled mail in the hosting settings by un-checking the "Activate mail service on domain" checkbox and there are no accounts in the domain. (Other readings have indicated that this should be enough to allow mail to be directed to the appropriate server). My MX records correctly point to the google apps mail server.
I'm quite comfortable with command line, but I know almost nothing about the sendmail program or its alternatives and my attempts at researching how to set up this relay has been futile. I'm pretty sure I'm using sendmail and not qmail or anything else from what the red-hat style "alternatives" symlinks point to. I've also checked the /etc/mail/access, domaintable, mailertable, sendmail.cf, virtusertable, local-host-names, sendmail.cf, and submit.cf and most of these files are empty (except the .cf files), and the sendmail.cf and submit.cf make no reference to the domain in question.
Here is the output from a sendmail test that was was not received. (Private data omitted of course). sendmail -v xxx@yyy.com test email from yyy.com webserver. please ignore. xxx@yyy.com... Connecting to [127.0.0.1] via relay... 220 my.server.com ESMTP >>> EHLO my.server.com 250-my.server.com ..... Closing connection to [127.0.0.1] >>> QUIT
Performing the same test and sending an email to a non-hosted domain works fine.
I have a Server with Webmin, Usermin and Sendmail using pop3s. I have created a seft signed certificate using webmin. Exported it and imported it to the trusted root certification authorities on my client. This fixes the warning message from internet explorer when attempting making a ssl connection to webmin. When attempting to use usermin or retrieving mail I get that warning that this site's certificate is self signed. I look at the certificate and its not the same as the one I created with webmin. My question is. Is possible to have the same certificate be used by each?
Can this be done? A company is currently running a postfix mail server. They got a new server and, while the users are migrated, they need to have the messages delivered on BOTH servers.
I thought it could be easily done in postfix: deliver locally AND forward mail to new server, but all solutions I found would deliver the messages in just ONE place.
I am researching the CentOS Cluster Setup. Does anyone know of a guide on this or have a thread linked that I can look at? I want to build a small cluster and then be able to add to it as it grows. Mainly I want to have web hosts, data, and mail behind it. The DNS will probably be on there own.
I need to setup a Linux VPN server at work for resources' sharing, I currently have a server running CentOS 5.4, and tried endless tutorials on the web, but to no avail, and can't find where the logs are kept for the VPN server to check where the error is. But all my attempts to try to connect keep failing.
This message was created automatically by mail delivery software. 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:
xx@xx.com SMTP error from remote mail server after initial connection: host [URL] [ip address]: 550 Access denied...
I have a problem relate to posttfix.I want to mirgare postfix mail server to exchange 2010 mail server but I can't do it,u can help me.You can show me have to do configure postfix and exchange how to?
How do I make a local mail server that itself is a client to a WAN mail server.I want the local mail server to query new mail every 30 minutes from the WAN server.
I've setup my server by following a ton of goods, and it seems to work ok, but I need to start using my server for email in order to receive orders placed via my website. I've followed this guide - [URL] I followed the steps above, and tested the mail server via telnet, and all seemed to be ok. I tried sending an email via Squirrelmail, from cs@thinclientwarehouse.co.uk TO my working email simon@c1systems.co.uk, but the server returned with the following message:
<simon@c1systems.co.uk>: host mail.c1systems.co.uk[95.128.128.129] said: 550-Verification failed for <cs@localhost.thinclientwarehouse.co.uk> 550-The mail server could not deliver mail to cs@localhost.thinclientwarehouse.co.uk. The account or domain may not exist, they may be blacklisted, or missing the proper dns entries. 550 Sender verify failed (in reply to RCPT TO command)
I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).
I was using an email server from Icewarp, Merak Mail server V8.0.3 with a keygen for total full free use... I liked this server package... as everything is in there I need and it is controllable from a single window. Now I am planning to move to Linux... They have a Linux version, but not stable and expensive. Is there any thing almost free/less expensive (Specially they need yearly payment for upgrade of even the anti virus and anti spam)?
I need a almost same thing (except of the ftp and VoIP) like Merak (because that I really liked for ease of administration) in Linux? Like a Qmail with real strong Anti Virus and Anti Spam, with unlimited domain and user+autoresponder, mailing list, etc all but controllable from one single GUI?
I am using read() in c++ to get data from a serial port. However, if no data is available on the serial port the function blocks until dta arrives.Example code:
iam trying to sync file server data into backup server machine by command- rsync -avu path/of/data ipaddress-of-backup-server:/path/where/to/save after running it ask for root password and manually it is successful.but i want to make it automatic.for that i also tried cronjob and also generated authentication key but iam not successful in login automatically..anybody know how to authenticate root to login for storing data in backup server.
iam using centos5.2.configured qmail,vpopmail. while adding domain form vadddomain<domain.co.in> At first time domain folder get created in domains directory.and also postmaster user also get created by default.And also in mysql. Now the problem is after some times or rebooting system domain get erased automatic.also in /var/qmail/users/assign file domain name get erased.
I'm working on a thorny mod_rewrite problem. I have a mac connected to my LAN running MAMP (Mac/Apache/MySQL/PHP). I request a non-existent file:
Code: http://192.168.1.2:8888/careers/db/1.html I see this in the mod_rewrite log file:
Code: 192.168.1.102 - - [14/Nov/2009:13:46:07 --0800] [192.168.1.2/sid#807df8][rid#8ec850/initial] (2) init rewrite engine with requested uri /careers/db/1.html 192.168.1.102 - - [14/Nov/2009:13:46:07 --0800] [192.168.1.2/sid#807df8][rid#8ec850/initial] (1) pass through /careers/db/1.html Note that the requested uri is /careers/db/1.html
If I change just the file extension on my request to PHP like so:
Code: [URL]
Then the request uri is totally different now. Here's the rewrite log:
Code: 192.168.1.102 - - [14/Nov/2009:13:47:23 --0800] [192.168.1.2/sid#807df8][rid#8fc850/initial] (2) init rewrite engine with requested uri /Applications/MAMP/htdocs/careers/ 192.168.1.102 - - [14/Nov/2009:13:47:23 --0800] [192.168.1.2/sid#807df8][rid#8fc850/initial] (1) pass through /Applications/MAMP/htdocs/careers/ Note that the requested uri now has a full path which does not include the actual filename, /Applications/MAMP/htdocs/careers/
What the heck? More info. If I request [URL], I can actually access p1.php. The requested uri is /careers/db/p1.php. The problem appears to be because the filename starts with a number. I can also request [URL] and get thru to 1.php with requested uri /careers/db//1.php. Does mod_rewrite think /1 refers to a backreference or something? Why can apache handle the html file request properly and not the php file request?
I want to host 5 websites on my new virtual server so I have created 2 nameservers that point to my virtual server's IP addresses as a glue record. What confuses me is when I create a new domain on my server it gives the new domain it's own nameservers (ns1.thenewdomain.co.uk etc) do I need to change these records so they use the nameservers I created earlier? If I do? Which particular records should I change? I'm running a Unix virtual server with a Plesk control panel.
