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'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?
I 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.
Is anyone successfully using cPanel with smtp port 587 and have a working email account?
After deciding that Plesk wasn't for me due to the lack of reference material in this and other forums, I had my hosting company, ServInt, delete my old vps and install a new one with cPanel.
Everything went fine until I configured my email. Just like with Plesk, I cannot access the smtp server via Outlook. I can ping it successfully, but it either terminates the connection or doesn't recognize the correct user name and password. With Plesk, it was a simple matter of enabling the use of port 587.
Not so with cPanel, at least for me. Even though the Exim service is enabled and another instance is enabled on port 587, I still can't connect. Thought it might be CFS, which is new to me with this install, so made sure it was disabled. Opened up a ticket with ServInt and even their techs can't get it functioning, so _they've_ opened up a ticket with cPanel.
Hence the title of this post, I can't beleive that I'm the only one whose had this problem before because blocking port 587 has been done by BellSouth/AT&T for many years now.
Nothing like having your company email down for over 6 hours to keep you up at night.
I 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 Trying ##.##.##.## ... Connected to mail.fakedomainname.com. Escape character is '^]'. 220 fakedomainname.com ESMTP Exim 4.67 Wed, 30 Jan 2008 00:56:03 -0800 HELO [192.168.2.1] 250 fakedomainname.com Hello reverse.verizon.net [##.##.##.##] MAIL FROM:<email@example.com> 250 OK RCPT TO:<firstname.lastname@example.org> 250 Accepted DATA 354 Enter message, ending with "." on a line by itself
This should not work . 250 OK id=1JK8kZ-0004Xx-7O quit 221 fakedomainname.com closing connection Connection closed by foreign host. asdfasdfasdf:~ username$
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.

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!

I have a customer that wants to send emails using Exim and SMTP (using outlook), withouth authentication. Now.. the big question is ... how can I configure the Exim server to work withouth any authentication?
I know the risks of this withouth any authentication, but is my customer's server and he want to work in this way.
He is also asking if he is able to send emails withouth authentication using SMTP for certain IP addresses.. is that possible? Can be done for only 1 domain, or for the entire server?
Alright now this is the most intelligent way to send spam I have ever seen. Apparently a guy has made a PHP or Perl script that is acting as an MTA. That's right: He is neither using Sendmail nor Exim but he made a script that acts as an MTA. That means the script itself connects to third party mailservers via port 25 and communicates with the remote mailserver as if it was an MTA itself. This works even if Exim is entirely disbaled...
The spam still get's sent. The script is running only occasionally...not like a daemon.
So it is nearly impossible to locate it. You have no Exim logs to look at. And in the Apache logs any PHP script could be it... You are not able to find that out. Therefore I am unable to stop him unless I manage to block outgoing connections to another host's port 25 for any program but for exim.
How can I configure my firewall (APF) so that only Exim my connect to other servers via port 25? Is that even possible?
Smtp service (qmail) stops responding on port 25: # time telnet localhost 25 Trying 127.0.0.1... quit quit Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. quit quit Connection closed by foreign host.

After server restart or sometimes apache stop or ixnetd restart its responding for a some random time, and then again it stops to respond. Plesk panel show it as stopped but qmail itself running in memory, and does other its work, it just stops responding at port 25, or responds with a huge delay.
I've tried change it to postfix, reconfigured with mchk, repaired with repair.sh -r, disabled and uninstalled parallels antivirus, antispam, dnsbl, disabled firewall, disabled smtp lock. Checked apache, dns. Enabled submission port which works when 25 port doesnt, but i need working 25 port.
Nothing solves problem, its just stops responding after some random time. There is no errors on maillog.
I think this problem occured after recent plesk microupdate, because i didn't do anything to server configuration in last months.
This article says it might be dnsbl [URL] .... but it disabled(from plesk panel) on my server, maybe there is way to focefully kill any relation to dnsbl?

update: xinetd restart is definitely brings smtp alive, but it goes off after random period of time (5min ~ couple hours)
After migrating our existing client base from legacy Plesk 9.x servers and Expand to PPA, clients phoned in with mail sending problems. These clients are using submission port 587 because their ISPs intercept port 25.
Existing client, Outlook error message:
"None of the authentication methods supported by this client are supported by your server"
Testing with Thunderbird, error message:
"An error occurred while sending mail. The mail server responded: 5.7.0 Must issue a STARTTLS command first. Please verify that your email address is correct in your Mail preferences and try again."
It seems a "fresh" PPA requires STARTTLS on e-mail clients. It is furthermore confirmed that Thunderbird detects the e-mail server settings as dependant on TLS.
The problem is that TLS doesn't seem to work properly by default.
In order to preserve our existing customer base, we follow: [URL] ....
Bottom line, in your /etc/postfix/master.cf, change the line that says "submission" from this:
