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.
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:
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 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?
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 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...

View 1 Replies View RelatedI have an office internal website and I opened a port in the gateway of my office (7080) to this website (server )'s 80 port. That makes this website open to public as office has static IP. And then when I view the site from home . it's fine. But when I tried to login, the site is using a pop-up, I guess it's http authentciation, login, I was redirected to a url without my port number any more, that stops my access to the site as obviously I would.
How can I keep my connection/port number ...?
about the NIC and switch,
there are giga port vs mega port,
in your experience,do they really be different?
I recently changed my SSH port, but locked myself out when my APF firewall was installed.
Where would I got to add a custom port inside the APF's config file?
I am using proftpd...How do i instruct that the server don't listen on high ports 49152-65534 but only to 21?
The reason is because my client's firewall setup is very strict and i need to give a good reason to open those high ports. Right now, i can ftp to port 21 only but can't do nothing more than that coz the higher ports are blocked.
i now have root access at a site i manage and the previous admin has set up a different SSH port.
I think this because i get " Connection Refused " and that user has access for SSH.
When restarting my SSH services i recive;
Quote:
sshd has failed, please contact the sysadmin.
And from looking that error up it means the port has been changed.
So i have WHMC access and all other root passwords etc, but how can i find out the port?

I'm a bit new to this, and I wanted to host my server on a VPS. I tried connecting, but that just didn't work. Do I need to portforward the VPS? Sorry, Like I said, I'm a bit new.
View 6 Replies View RelatedI know this is a bit of an odd question but I have a VPS which has port 1189 open. Is it normal by default to have this port listening on a OpenVZ VPS under HyperVM? or is this something a little concerning? Never noticed it before, just checking I don't want any illegal applications being hosted on my server by clients.
It's most probably nothing to be concerned about, just wanted to double check.
I would like to know on how to forward specific IP with port to localhost or any IP by using iptables ? For example i would like to forward for port 25 from IP A to IP B, Currently i'm doing a test with my firewall and i'm very blur with iptables thingy.

I've noticed on some rackmount servers and firewall appliances there are ports labelled console, and look like serial ports. Are these related to connecting to KVM? I am looking for a cheap appliance for some rackmount servers I have (1U half depth would be ideal), to remotely recover the server if it goes down. I figured they'd connect through PS2 connectors, but then I thought that if the console port was related, then going through that might have the option for power cycling or something.
