I have a server at The Planet that runs Cent OS with cPanel/WHM. It is using Exim as the mail transport.
I am having a problem with gmail.com accounts relaying mail through my server.
I would like to have only domains that I host be allowed to send mail through my server. How can I accomplish this?
How to dump all relaying email?
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:
Is there any sense to upgrade to cent os 5?I mean,is there any critical benefit which will increase server performance if i do that.I noticed i can upgrade over ssh but since that will generate downtime i wonder is there a sense to do that.
View 1 Replies View RelatedOne 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.
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'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 have a server in our office which is used as a share drive. Puts all accounting docs on it ect. After 6 or so, it will loss all conectivity completely. Yet the server still stays on. We installed everything in all packages on the server including it graphical interface. We havent mucked with any of the powersavings so what could it be. Also there is nothing plugged into it eg screen,keyboard and mouse. All that is connected is the power cable and the ethernet cable. That is it.
It is directly connected to a belkin wireless router
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] ....
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...

I noticed with every new cent os server there are different mirrors for cent os repos.Since on each cent os repo file is same,how does it pick which mirror it pick?I ask beacuse latest server has picked one extremly slow edu mirror which is not just slow,it also timeout,and it may extend update to 2 hours instead 5 minutes which usually will take.So how do i change base mirror on base cent os repo?

how to check which version of cent os is used?
my friend ordered an vps with a host, he ordered 5.3 - 32bit but some how I feel he has been provided with 5.0 version by the host, I didn't know how to confirm it, when I checked his hypervm, this was the cent os details provided:
Ostemplate: centos-5-i386-hostinabox576
there is rebuild option in the hypervm and in tht when I look out,here it shows the following:
[url]
what my friend exactly needs is a cent os 5.3 - 32bit system, so if he selects cent os 5.3-ix386 (full) will it install with cent os 5.3 ?? he doesn't want kloxo to b in there auto, he/I can install tht,

I have a problem with the email accounts .. All of it doesnt work when i try to check them on microsoft outlook .. i'm using a whm/cpanel on a VPS from godaddy. When ever, i try to "Send & Receive" emails, i'll be prompted for the user and pass. Even when i've entered the correct one, i'll still be prompted again. I believe its one of the settings in my whm/cpanel as i have no problems with the other email accounts that i'm using from a different shared host.
View 8 Replies View RelatedI've been concerned that my cPanel email address on my dedicated server hasn't been receiving emails. This was confirmed when an email sent by request from a friend did not arrive. The address is fosterd(***at***)pcfastlane.com if anyone would like to send me a test email.
What are the steps I can take to see if my cPanel email software is running correctly? I have already looked into my mail statistics, and it seems as though there are messages not being delivered, a fair amount which seem to be spam, but others that may not be.
MPORTANT: Do not ignore this email.
The hostname (server.mydomain.com) resolves to . It should resolve to xx.xx.xxx.xx. Please be sure to correct /etc/hosts as well as the 'A' entry in zone file for the domain.
Some are all of these problems can be caused by
/etc/resolv.conf being setup incorrectly. Please check this file if you
believe everything else is correct.
You may be able to
automaticly correct this problem by using the ' Add an A entry for your
hostname ' under ' Dns Functions ' in your Web Host Manager
My provider is using mailfoundry for spam filtering.. but I used IMAP (stored on server) for email.. my problem is that I'm also using a catch-all address and I make up random email names for sites I go to, to check for spam on the incoming side..
I setup filters in Cpanel to remove the selected spam or emails I don't wish to recieve.. but they don't seem to remove themselves.. it could just be a setup problem or it could be the mailfoundry.. not sure..
Here's the settings I have in cpanel (I just altered the name) is this the right setting.. or does it go elsewhere?
