Exim SMTP Sync Error
Jan 28, 2007
I recieve the error when ClientExec is trying to send email in my rejectlog...
2007-01-28 20:53:17 SMTP protocol synchronization error (input sent without waiting for greeting): rejected connection from H=[255.255.255.255] input="EHLO host.domain.net

I added host.domain.net and 255.255.255.255 to the whitelist files and added this ACL to exim.conf after begin acl:
acl_check_connect:
accept hosts=255.255.255.255
control=no_enforce_sync
accept hosts=host.domain.net
control=no_enforce_sync

If it matters, I am running CentOS4 64-bit, DirectAdmin, Kernel 2.6.18

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.

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:<nonexistentuser@fakedomainname.com>
250 OK
RCPT TO:<myvalidaddress@gmail.com>

.
250 OK id=1JK8kZ-0004Xx-7O

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.

running 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!

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?
Im using Exim 4.6.8 and RHE 4 + cPanel.

any 'easy' smtp / pop / imap package or installer w/o having to read up on exim etc.?
I want an email server quickly, w/o having to become an expert...
I'd go w/ a hosted service, but I open allot of pop3 connections... (program I use downloads one email, closes connection, reopens... repeat)...
There's lots of cookbooks out there, but they require quite a bit more time commitment (and configurability) than I want / need.
Is there any dumbified installs available? I tried with webmin, but even that wants me to manually configure a postfix / imap server bridge.=

We have a few users that use SSL email and we decided to purchase a cheap single-root SSL cert over at namecheap for the host name so that it would end the "self-signed cert" whining.
We got the cert installed and it works great for WHM/cPanel and also works for SSL over IMAP and POP3, but the very first email anyone sends (SMTP) per day gives this warning (Outlook Express):
The server you are connected to is using a security certificate that could not be verified.
A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider.
It seems obvious that the cert used by the SMTP system is not the new one we installed.
We used WHM's SSL/TLS -> Change Server Certificates link to install the cert.
We then made sure that:
/usr/share/ssl/certs/host.domain.com.crt
/usr/share/ssl/private/host.domain.com.key
/etc/exim.crt
/etc/exim.key
...all contained the current cert or key as appropriate.
Just for grins, we even made sure:
/usr/local/cpanel/etc/cpanel.pem
...had the correct pair.
We restarted all the mail services and even restarted the whole server. (I know...Windows reaction...bad tech.)
Does anyone know of a stealth location where the SSL cert for SMTP should be updated?

installed on CentOS 6 and Plesk Version 12.0.18.
I initially had trouble where everytime i tried to load webmail.domain.tld i would have a DNS error, I've resolved this by correcting the DNS settings on my domain and now i can login to the webmail and recieve emails. Now, whether i use Horde or Roundcube i get this authentication error for my SMTP. I'm very new to this stuff and i'm not sure where my log files are or what the issue could be or even how to fix it.
