Jun 27, 2008I have a cPanel server with CSF installed.
Today I face a problem having SMTP Relay attack
I Enabled SMTP Tweak inside WHM and it prevent the relays
But I am still seeing a huge attack inside my exim_mainlog through one of the domain hosting in the server.
I Delete the domain DNS zone, Change the domain name server, it still doesn't stop the attack. How do I go with this? Need help for those experienced in this...

Perhaps you have not logged into the pop/imap server in the last 30 minutes or do not have SMTP Authentication turned on in your email client.

View 7 Replies View RelatedSMTP Auth From A Relay: How Do I Get Around This
Jul 17, 2008I'd like to describe an issue and see if this sounds familiar to anyone, or if there is a solution that I have not thought of yet.
CAUSE: My ISP (yeah, it's comcast) began blocking port 25 inbound so my personal mail server was no longer receiving mail.
RESOLUTION: I worked through a new DNS re-router to change the port that would now receive mail: from port 25 to port 587. It took me a while to get the routes pointed correctly, but I finally got the messages to route, get through my firewall, and hit the mail server.
NEW PROBLEM: After some IP and DNS routing issues, I finally got things to work, the email that gets sent finally arrives at my mail server. However, the mail server (Alt-N MDaemon) now requires AUTH from the incoming DNS re-direct.
BIG QUESTION: How do I configure MDaemon mail server (or any other mail server, for that matter) to accept the mail from the new re-route server? Mail now re-directed to the new port ALWAYS comes from that route (mx-routes01.editdns.net). Where in the configuration settings of MDaemon do I set it up? I've tried including the host name and the IP address into every WhiteList list I can find, added it to the trusted host name list and everything. I'm at a loss, since it's impossilbe to configure the re-route server to provide AUTH credentials to my mail server. MDaemon now replys to every mail reuqest with : 530
Authentication required (in reply to MAIL FROM command)
SMTP Relay Service
Jun 17, 2007Anyone know of a good place to do SMTP relaying through?
We have legitimate clean email that we need to send for my site that gets filtered as junk mail for the major free email services (Hotmail, Yahoo mail, AOL mail, etc.). Unfortunatley it is legitimate email that needs to get through to the end user to register their account.
Right now we use the free 250 smtp relays per day that come with our free GoDaddy hosting account but we are quickly approaching the need to send more than 250 a day and GoDaddy charges a healthy amount for more than 250 a day.
Anyone know of a good economical SMTP relay service?
Reached SMTP Relay Limit
Jun 11, 2008GoDaddy says: "You have reached your current SMTP relay limit of 1000 per day on the following hosting account" But they assigned a limit of 1,000 -- and i don't use SMTP relay at all. I have set up my active email accounts to use Google SMTP. When I tell GoDaddy about this, they tell me it is my responsibility. So what do i do?

Mar 31, 2008I have a dedicated windows 2003 server that acts as an smtp relay (legit purposes, not open).
There are large amounts of mail relayed through the server and I would like to install some 3rd party software that can scan the messages/attachments for viruses.
Ideally, if one exists it strips it from the message and notifies the recipient and/or sender of the problem.

Postfix SMTP Auth (Relay) Problem
Apr 2, 2009I've been trying to set up Postfix to send email for the past few days. I've managed to get it to ask for a username and password, in order to try and send mail to an external domain
I can receive email fine on the server, but I can't send email out
Here is my main.cf file
Code:
command_directory = /usr/sbin
daemon_directory = /usr/lib/postfix
data_directory = /var/lib/postfix

smtp_sasl_mechanism_filter = login
myorigin = literatifoundation.org

When I try to login to send the email, it doesn't accept the password.
Exim Outbound Relay Per Domain
May 4, 2008I have been searching for a solution to a problem that shouldn't exist but it does.
Background:
I have a customer on a UK server who sends emails to 500+ recipients on a monthly basis, and all but 3 emails are delivered....
The 3 that don't go, bounce after 3 days (as per the exim setup)
The 3 recipient domain's that reject don't seem to accept email from UK/European ip's and I have tried to send them emails from 4 different networks and still they bounce.
I have even tried to contact them via gmail, and still not heard back.
Proposed solution:
I want to be able to send email for that 1 domain to a Postfix Relay I have in the US.
Question:
How do I achieve this within Exim (a Cpanel Server).
I have found that so far its to do with the Router Configuration section within the Cpanel Exim setup, but I cannot seem to find an example of what and where i need to change the config...
Can anyone provide an example?
Exim Server - Being Used To Relay Spam?
Dec 3, 2008Exim server - being used to relay spam?
Hoping someone can help here. I have a web server running a couple of sites, has been for a couple of years now. With one of the domains, I have an email forwarder setup through cpanel to forward mail sent to a specific address at that domain to my gmail account (it's a "contact us" type address). I don't think the email address is listed on the web anywhere.
Anyway, I am noticing a lot of spam emails being sent to that address, from that same address and they all appear to be relayed through my exim server legitimately. Obviously they aren't (as I am not sending them).
I am only familiar with sendmail, and am unsure about where to look for any possible hacks to my exim server. Can someone point me in the right direction? I want to stop these spam messages being sent, asap.
Plesk 12.x / Linux :: External SMTP Relay Not Sending Email From Panel
Apr 8, 2015I have Plesk 12 on CentOS 7. I have only MSMTP installed not Postfix or Qmail. No matter what settings I use in the external SMTP settings the mail is never sent and I cannot find any error logs.
I have tried gmail smtp, sendgrid smtp and another smtp server that I own.
This is not a firewall issue as far as I can tell since if I install postfix it just works. Also any Wordpress or Joomla installs that use SMTP settings with gmail or sendgrid work just fine.
Screenshot for information only. I used accurate usernames, passwords, etc.

Quick update. I tried the recommended CentOS 7 with the same result. Can installing Plesk 12 without a mail server and using the msmtp relay option actually works?Click to expand...
Exim SMTP
Apr 26, 2008I've recently purchased a cPanel VPS from a company i found on this forum. However, i am not experiencing some problems with the sending of e-mails from the server via Outlook Express. Unfortunately, i'm have no real knowledge of EXIM and i was hoping someone would help me with this. Basically, when i setup the domain and then setup a email account, i could only receive emails and not send (as i was getting an error within Outlook) this was due to the fact that the domain name was not listed in /etc/localdomains, so when i added it to that file it seemed to have done the job. Now, when i send emails locally EG: example1@domain to example2@domain i t will indeed send correctly, however if i want to send it to an external domain it stays in the queue (which i can view in WHM). When i force send it, it gives me the message "Connection refused", can anyone shed some light on this situation?

Jul 10, 2015After setting up a new server on Plesk12, I successfully ran some test mail outs using phpmailer using the SMTP server on this machine
However, there was an issue in creating new local mail accounts in plesk with an error message each time.
Investigating this issue led me to a solution that I should run mail_restore from the Plesk scripts
This cured the problem of setting up new local accounts but outgoing SMTP mail is always failing with 'relay access denied'.
Exim Smtp-after-pop Authentication
Jun 8, 2007I use Exim + Dovecot for my mail server. We can get mails through pop3 protocol without a problem, but when we try to send mails, exim does not permit relay. My passwords are stored in a mysql database for dovecot. Is it possible for exim to do authentication based on that? If it will be easier, i can create a text file with md5 passwords on it for my users.

Jan 30, 2008I really hope I'm just going batty with sleep deprivation, because this is making no sense to me. Before I clobber my poor provider with management requests, I want to see if this is typical behavior or not. I am able to send messages through my SMTP server from my laptop without using any authentication at all. It doesn't matter whether I'm using a client (tested Mail.app and Mozilla Thunderbird) or whether I'm going in via telnet. A typical session might look like this (addresses obfuscated):
asdfasdfasdf:~ ###$ telnet mail.fakedomainname.com 25

I was expecting to see a "550 authentication required" message after it saw that "RCPT TO" wasn't a locally-hosted domain. I did confirm that the message was properly delivered to the intended Gmail address. So far, it looks like an open relay. But when
I use a third-party environment, such as the open relay checker at abuse.net, I am correctly seeing "550" messages at the appropriate places.
In other words, when anyone else does it, they get "550". When it do it from my laptop (from any client or telnet session), I'm clear to send. Just to add a little zest to the situation, when I did this same test 36 hours ago, I *was* getting "550" errors.
This doesn't seem right to me. However, my mail admin skill level is approximately zero, so I'm willing to accept that this is normal behavior and that I am overlooking the obvious.

WHM Exim Does Not Refuse Emails During SMTP With :fail:
Feb 7, 2008running WHM at Fedora 6... WHM 11.11.0 cPanel 11.16.0-R18546
I have a problem with spoofing spammers.. my queue is plenty of non-delivered emails from externals SMTP, sended to NON-existents address on my server...
The question is the destination domain (mydomain.com b.example) has already its ":fail: No Such User Here" alias.
SMF records applied, but not the most external SMTP servers checks them nowadays...
Using :fail: the email is never accepted into the server. During the initial SMTP negotiation when the senders SMTP server connects to your SMTP server, the sending SMTP server issues a RCPT command notifying your server which email address the email to follow is intended for. Your server then checks whether the recipient email actually exists on your server (a POP3 account, an alias or a catchall alias) and if it does not, it issues an SMTP DENY which terminates the attempt to deliver the email.
Well, in my case it justs receives message and then frozen it!
