Red Hat :: Sendmail 8.13 - Can't Send Mail To Own Domain

i have running sendmail 8.13 on my red hat enterprise linux 5.1, but i have a problem. I can send a mail from my line command terminal to hotmail, gmail, yahoo and any of these, but i can't send mail to my own domain ([URL]), when i wrote a mail i get a reply from MAILER-DAEMON@localhost.localdomain that says that the message had pemanent fatal errors and shows as user unknown the mail was suposed to recive the message.

For example, if i send one mail from to the user2 does not recive any mail, but that doens not happens if user1 sends a mail to any hotmail address or gmail or any other. Besides i also can't recive on my server any mail to or (for example), so please tell me what do i do to get the mail.

Fedora :: Unable To Send Mail Since Sendmail Package Update
the sendmail packages on my f15 server were updated from 8.14.4-20 to 8.14.5-1 yesterday. since then, every attempt to send mail via a smart relay have failed with :

Jun 25 14:05:10 server sendmail[23512]: p5PD59jr023512: from=root, size=208, class=0, nrcpts=1, msgid=<201106251305.p5PD59jr023512@server.{fromdom ain}>, relay=root@localhost
Jun 25 14:05:10 server sendmail[23513]: p5PD5A8l023513: from=<root@server.{fromdomain}>, size=480,


i've tried using various different smtp relays and they all now throw the same error. without going through all my sendmail config, i have the following entries in /etc/mail/ :

define(`SMART_HOST', `{smtp server}')dnl
FEATURE(`authinfo', `hash /etc/mail/authinfo')dnl

and the /etc/mail/authinfo file contains :

AuthInfo:{incoming mail server} "U:{user}" "P:{password}"

Ubuntu Installation :: Redmine And Sendmail - Can't Send Mail From Server
I'm currently running Ubuntu 10.10 Server using VirtualBox 3.2.12 r68302. I've setup a LAMP Server and Installed Redmine and I'm going to be starting some projects. The problem I have is that I've linked it to a subdomain thru my hosting, so things are a little more complex for me then usual. Here's the software I've added for this setup:

Ruby version 1.8.7 (i686-linux)
RubyGems version 1.3.7
Rack version 1.1


how mail server functionality works as well as how to properly set the host of the virtual pc.

Server :: Sendmail SMTP Send Doesn't Work With OS X 10.6 Clients
I've been having this problem since 10.6 released, but have until now been successful with the "just use Thunderbird" response. My sendmail server hasn't been changed, but as clients upgrade from OSX 10.5 to 10.6 suddenly will no longer connects to send SMTP messages through the server. (IMAP connections to the same server using the same user/pass combinations work perfectly) When I look at the logs, things basically stop right after the STARTTLS command.

Google indicates alot of people are having similar problems, but I'm not seeing any solutions. Do any of you administrate sendmail servers where some of your clients are using Apple's on Snow Leopard, and if so what settings are you using? At this point, I'm happy to make changes to the server to accommodate Apple's issue, I have too many Mac users connecting to my server. I just can't figure out what to change. I've enabled virtually every possible login authentication combination, and none of them work.

Networking :: Sendmail Error 550 Host Unknown / Cannnot Send Mail To An External Address?
I've struggled with this problem for days. I cannnot send mail to an external address with sendmail. I can receive and send local mail and I can receive external mail. I am sending out of a router. At wits end, I am providing as much information as I can imagine will be helpful to help me solve this. The stated culprit is this host unknown error. But I know the mail server smtp is correct: url. I even checked the nyclug if anyone had problems with road runner. I can telnet localhost, the url mailserver. I know the port 25 is open. I suspect that I need to change host server name in etc/host, but I have had no success. Is this an access file issue? Is gmail just bouncing back my mail? I want to solve this because that is what we do. I understand that I could use another application, but lets solve this one.

Here is th MAIL LOG:

Apr 8 11:04:26 darksun sendmail[22020]: k38B4QLH022020: from=<>, size=289, class=0, nrcpts=1, msgid=<>, proto=ESMTP, relay=mark@localhost

Ubuntu :: Postfix Emails Send Outgoing Mail With Wrong Domain Name?
I just configured my first postfix mail server today. Everything is working correctly except for the fact that on all outgoing emails instead of the mail format being it says user@hostnameofpostfixserver. I've looked everywhere I can think and I cant see where I'm substituting the host-name of the server for the domain name of my email. Where else could it be?Below is my I am running ubuntu 9.10.# See /usr/share/postfix/ for a commented, more complete version# Debian specific: Specifying a file name will cause the first# line of that file to be used as the name.

Server :: Plesk 9 - Send Domain Mail To Offsite / External Host
I am managing a Fedora dedicated server with Plesk 9 and just recently moved the email for one of the domains on the server to Google Apps for business. Unfortunately, I cannot get email messages from the website forms to deliver to addresses on this domain. For anyone familiar with Plesk, I have disabled mail in the hosting settings by un-checking the "Activate mail service on domain" checkbox and there are no accounts in the domain. (Other readings have indicated that this should be enough to allow mail to be directed to the appropriate server). My MX records correctly point to the google apps mail server.

I'm quite comfortable with command line, but I know almost nothing about the sendmail program or its alternatives and my attempts at researching how to set up this relay has been futile. I'm pretty sure I'm using sendmail and not qmail or anything else from what the red-hat style "alternatives" symlinks point to. I've also checked the /etc/mail/access, domaintable, mailertable,, virtusertable, local-host-names,, and and most of these files are empty (except the .cf files), and the and make no reference to the domain in question.

Here is the output from a sendmail test that was was not received. (Private data omitted of course).
sendmail -v
test email from webserver. please ignore. Connecting to [] via relay...
>>> EHLO .....
Closing connection to []
>>> QUIT

Performing the same test and sending an email to a non-hosted domain works fine.

General :: Send Mail From Domain As A User That Does Not Exist As Well As Email From Other Non-existent Domains
I have a server with a static IP that I use as a sendmail server. The problem is that port 25 is exposed. As a result, anybody can login to the SMTP server and send mail from my domain as a user that does not exist as well as email from other non-existant domains. I'm sure there are sendmail options that I can enable to do some checks, like if the user exists on that server or if the domain is the same on the server, etc. I was wondering if you guys can mention a few that I can add to my file?

I have thought about auth login, the problem is if auth login is on my public port then I won't be able to receive email from gmail because it would be unauthenticated. Also, I only have 1 mail server. I know the ideal solution is to have 2 mail servers. One for outgoing mail/internal mail server where you can enable auth login and the other for incoming mail which just acts as the relay to the internal mail server. That way spammers can't login to send mail out. That's another question I had, how do I configure sendmail to only send email out/in?

Anyhow, so I have to make do with 1 mail server for now. So I decided to add a few rules on iptables. I grabbed the IP range that gmail uses when I receive mail from then and added it to my iptables with the following command.
