FedoraCore2 - Cannot Telnet Out To Port 25, So Cant Send Email
Jun 23, 2005
if i try to telnet to yahoo's mail server, i get this:
[root: #] telnet mx1.mail.yahoo.com 25
telnet: connect to address 188.8.131.52: Connection timed out
telnet: connect to address 184.108.40.206: No route to host
telnet: connect to address 220.127.116.11: No route to host
telnet: connect to address 18.104.22.168: No route to host
but it works from one of my other hosted servers.
this keeps mail building up in my queue as it cannot send mail out cause the connection times out.
I can telnet locally to send myself email. This is my own dedicated server.
i have no idea whats up - default policy is ACCEPT in the OUTPUT chain of iptables.
I decided to disable Telnet in my server. I get an Article ::
1. Login to your server through SSH and su to root. 2. Type pico /etc/xinetd.d/telnet 3. Look for the line: disable = no and replace with disable = yes 4. Now restart the inetd service: /etc/rc.d/init.d/xinetd restart 5. Turn off it through chkconfig as well because it can still start through that. /sbin/chkconfig telnet off 6. Scan your server to ensure port 23 is closed. nmap -sT -O localhost
Also run ps -aux | grep telnet and if you find anything other than "grep telnet" as result kill the process.
But /etc/xinetd.d/telnet doesn't exist in my server.
Currently I am using Linux + cPAnel and using the port 25 for email sevrer. Currently we facing 1 problem is, some user's ISP is not support port. May I know how can I add additional port into server and allow users to send mail by different port?
I'm having difficulty sending an email to another email address (with a different domain) which is on the same VPS.The trouble is, on the other domain's VPS control panel, within the DNS settings, the MX records have been pointed externally (to an exchange server). Their email is turned off. But bizarrely, their mailbox is full.
It seems as though Plesk is ignoring the MX records, and sending MY email internally to the OTHER domain's mailbox on the same VPS.How do I get Plesk to send my mail to the correct EXTERNAL MX records?

my datacenter reply me :
Hello,We have investigated your issue in detail. We tried to sent mails from the server to our Softlayer hotmail account. From the logs, it is clear that the mails are sent successfully from the server.=========2007-11-23 23:50:29 1IviI1-0001De-SX <= root@server.XXXX.net U=root P=local S=3612007-11-23 23:50:30 1IviI1-0001De-SX => XXXX@hotmail.com R=lookuphost T=remote_smtp H=mx3.hotmail.com [188.8.131.52]2007-11-23 23:50:30 1IviI1-0001De-SX Completed========But this is not received at the hotmail mailbox. Hence this is an issue at their end. You may contact the hotmail support to resolve this.Regarding the spamming, we could find a lot of mails from the user nobody. You can prevent the user nobody from sending the mail from WHM as follows.Please select the option "Prevent the user "nobody" from sending out mail to remote addresses" from WHM >> Main >> Server Configuration >> Tweak Settings >> Mail option.
I currently have a vps, just name it myvps.com (not subname.myvps.com).
I wanna send email to email@example.com from php
php with sendmail function always try to send to user 'someone' on this vps that doesn't exist, junk the root user mail with mailer-daemon explaining that no such 'someone' user. I want to route it to another server.
SPF correct DNS correct Submitted to sender ID 2 weeks ago Mail server tested to other mail clients all ok GMAil header test. SPF pass DNStools test: reverse dns, all ok Blacklists checked. Im not on it
I cant find any reason anymore why my mails dont arrive.
I have a dedicated server with godaddy and it has squirrel mail/sendmail/dovecot etc installed on it. I am able to log-in to squirrel mail but when I try to send email, it fails. Even it's not able to receive email. I restarted sendmail but it still does not works.
I tried to send email through command line but it does not work either.

I recently moved a site from a hosting company to a VPS. I updated the name servers with the domain name registrar and the transfer went smoothly.
However one thing does have me puzzled. As I understand it (and correct me if I am wrong) my new hosting company are now the authority for my zone and should have a zone file which points my domain name at one of their IP addresses? However my previous host has a webbased email panel - if I log in to it I can still send email (but not recieve). This has confused me as I would have thought that my new ISP would have a zone file with an MX record for my email? How is this possible?
Is anyone aware of any good tools or tips that I can use to monitor use of qmail/sendmail to generate and send email messages from PHP scripts on a web server?
I want to keep a check on sites that are sending email from the site, to make sure they are not being exploited and result in our server getting blacklisted by big service providers. I'd love a tool that would automatically block messages from an account after a certain threshold is hit.
I'm running a Plesk 8.1.1 & 8.2.0 server configuration..
I have a reseller account that uses WHM/cPanel. So of course, SquirrelMail and Horde are already installed. I like to check my email at work, but unfortunatley, my employer blocks connections for say mydomain.com:2095.
Is there a way around this? I'm too much of a noob to try and install Horde again, bypassing the cPanel. I use Horde as the example because I need a good calendar and address book.
It appears Comcast is now blocking port 25. As a result, I can't sent outbound email via my dedicated server. They had me change to port 587 for my comast email account, but that doesn't solve my not being able to send outbound from my dedicated server.
Is there anythighn I can do (like change the post my mail server uses to 587) so that I can send outbound mail from my server with outlook (over Comcast connection) or am I just stuck now with using web mail?
We have been running our web/ftp/application/mail server for about 4 years, and running flawlessly. This week one of the computers in the network was infected with a virus that was sending spam like crazy. We got blacklisted, as per this site mxtoolbox.com. Our domain is affordablerto.net. Since then we have isolated the problem, klilled the virus and are no longer blacklisted. But we are not able to send or receive any emails now. I wrote mxtoolbox and there reply was basicly "We can get you up and running if you pay us". I called our ISP and they stated that the ports(25) are open. When I do an smtp diagnostic from mxtoolbox I get the response that Argument 'Length' must be greater or equal to zero.
When I go to dnsreport and input our mail server (mail.affordablerto.net) I get ERROR:
The parent servers say that the domain mail.affordablerto.net does not have any NS records (although they may have some other information on that zone).
When I put in our mail server under mail test I get this Getting MX record for mail.affordablerto.net (from local DNS server, may be cached)... There is no MX record for mail.affordablerto.net! That's bad. Checking for an A record... Got it!
When I put in our domain I get this...well I can not put a link in yet - the software here says I need to take 5 posts before I can link anything. Go ahead and try it yourself.
I am not sure what most of this information means. I am in contact with our DNS provider and they keep on trying to sell me some solution. So does mxtoolbox.
suppose my domain is mydomain.com, my sendmail may send email to any domain name except local domain, say, sendmail may send email to hotmail, yahoo or any other domain name, but when send email to emailbox under mydomain.com, sendmail log will say domain not found.
My situation is my server does not have DNS service, my DNS service is outsourced, and MX record also is outsourced.
