I used Zimbra since a week ago to my centos 5 server, but now I'm using google apps. Today I tried to uninstall Zimbra and restore sendmail, but when I try to send a mail to local domain, it responds with an unknown user message and don't deliver the message to google mail.What I forgot in reconfiguration?
View 13 RepliesI'm running CentOS 5.4 with sendmail. My computer hostname is bob.domain.com. Whenever I would nc -v 127.0.0.1 25 into sendmail I would get bob.domain.com on the banner. Whenever I send out email the emails would be user@bob.domain.com. I wanted the email to show up as user@domain.com. So in the etc/mail/sendmail.cf file I changed the line
Code:
Dj$w.hostname.com
to this
Code:
Djhostname.com
Now when I enter sendmail I see domain.com in the banner so I know the change took place. However, when I send email using
Code:
mail -s "test" xxx@xxx.com
then email still goes out as user@bob.domain.com. What other changes do I need to make?
I have a Centos 5.5 Server, Servername is CentOS1. It has a Forum and a HelpDesk. The Help Desk software SENDS and acknowledgement to the user and emails to all the people on the support desk. Users can reply to emails only by accessing the helpdesk NOT by mail. Thus the server is configured to only SEND mail and not to receive any mail at all.
Mail Server is Sendmail.
Hosts file reads : -
# Do not remove the following line, or various programs that require network functionality will fail.
127.0.0.1CentOS1.tech.xxxxx.com CentOS1 localhost.localdomain localhost
::1localhost6.localdomain6 localhost6
There is NO MX Record because this server receives NO mail, it's send only. Unfortunately, the mail it sends has a From Header which is @CentOS1.tech.xxxxx.com. I want it to send from @xxxxx.com. I've read all the howtos on Masquerading and I've tried many, many things, but with the same results. It will NOT change the From. I had it working perfectly a long time ago with a SuSE server, but I can't for the life of me remember what I did. I know I also battled a bit.
The last few lines of sendmail.mc read : -
LOCAL_DOMAIN('localhost.localdomain')dnl
dnl #
dnl # The following example makes mail from this host and any additional
dnl # specified domains appear to be sent from mydomain.com
dnl #
dnl MASQUERADE_AS('xxxxx.com')dnl

dnl MASQUERADE_DOMAIN(tech.xxxxx.com)dnl

Ok, I have a couple of SMTP servers for our infrastructure. They are running Postfix. I have them configured so that specific email addresses such as support@mydomain.com and billing@mydomain.com all go to a new support server that I am building with osTicket. Lets call that server SUPP1.
SUPP1 runs sendmail from the default install of CentOS 5 i386. At this point everything runs great. New emails get added into the osTicket system via a pipe in sendmail. Here's where the problem comes in. In order to accept mail, sendmail has to have the domain listed in local-host-names and the addresses in virtusertable. That works just dandy. But in doing so, sendmail believes it is the destination SMTP server for "mydomain.com". That means that I can't send mail from that server back into my normal SMTP servers. So things like the LogWatch, cron jobs, etc can't send notifications. Is there a way to work around that? For sendmail to ignore local-host-names for outbound email or something?
From my main Postfix SMTP heads, I am sending just a couple select emails (primarily support emails) off to a server that receives them and pipes them into the support software. So far this totally works perfectly and I am pretty happy with the configuration. However, in order for sendmail on the support server to receive those emails I have to place them in the virtusertable of course, but I also have to activate their domain in the local-host-names file. That then causes sendmail to consider itself as the destination server for that whole domain.Is there a way to make sendmail receive email for select addresses without making it think it's the server for the whole domain? This server is only receiving email from two specific smtp servers, so I wonder if I could just permit relaying? Wonder if that would just cause a giant loop though.

We have a Windows 2K8 domain with Exchange 2010. I have setup a Ubuntu Server to be used as an internal wiki. Installed AMP on it and have MediaWiki running. Now I would like to setup SendmailToWiki extension. The only problem is that I do not know how do I make sendmail to work inside the LAN her with the Exchange server? This is the extension: [URL]
The e-mail address that is used in the extension is dynamic(changes for every user, since each user sets its own pinkode). And the script sets the domain part off the email to the last part off the IP of the ubuntuserver. For example: wikipost+2.12345@62.85. I cant send an email to half of an IP, can I? What I need to configure or not?
What configurations will be required in DNS and sendmail server to send mails from one domain abc.com to other domain xyz.com.

I am trying to set up a mail server on centos5 using sendmail and dovecot, and eventually spamassassin and some antivirus filter as well. I'd also like to get the proper secure auth mechanism set up at some point too. But for starters, I've been having a lot of difficulty trying to even connect to the mail server from a client computer in the local network. I installed Eudora on the client and after some tweaking in dovecot I was able to connect to the mail server, but then when I try to send an email I get a "connection refused" error, with nothing being logged on the server that I can see.
The last time I set up a mail server was Fedora Core 2, so the configuration files have changed a bit to say the least, and I can't really refer back to those to set up this new server. Does anybody know of a good step-by-step doc on getting the mail server going? I've read the man pages and other various readme's, but these really only list out the available options with no really good explanation of what needs to be done to get the mail server going. If there isn't a full write-up on how to do this, I'll put something together when I'm finished so others can use it in the future.
I run a CentOS server and would like to put a disclaimer message on every email that is send through that sendmail server.

My question is what is the default location of the badmail folder in Sendmail? This is a default install from CentOS.

After upgrading to CentOS 5.3 my sendmail will no longer deliver messages using a program in my /etc/smrsh. It fails with the message "unknown mailer error 1". This program was working perfectly before I did the upgrade using yum. Here is the list of packages that were upgraded. Does anything jump out as being the source of the issue? I don't believe that sendmail itself was upgraded:

dbus-libs - 1.1.2-12.el5.x86_64
libselinux-utils - 1.33.4-5.1.el5.x86_64

I am trying to make my webserver a well respected email sender and it appears to me that using DKIM is something I need to do.
I have no experience with this and would like to know if anyone thinks there are issues that I should be aware of before going down this path.
Also, I have not been able to find any good, STEP BY STEP, documentation on how to set up DKIM with Sendmail.
I am also not sure if you need a certain network configuration for DKIM to work...this is what I am working with:
My webserver (centos 5.3, sendmail 8.13.8) sends outgoing mail and has a valid reverse DNS that matches a forward DNS. The MX records for my webserver's domain point to a third party email provider who handles the incoming mail for that domain. I added an spf record that signifies it that my webserver is authorized to send mail for mydomain.
I have been trying to get procmail working on CentOS 5.2. I don't need anything fancy, just an auto reply for a "noreply@" account. Looking at the sendmail configuration, it appears procmail is the MDA. I have looked at many different tutorials and how-tos, but most are old, and/or the locations/paths and setups are markedly different from the defaults on my system. Can anyone recommend a good CentOS-based tutorial on Procmail w/ recipes? (I have an RHEL book and it's no help either.) Thank you for your time and consideration.

We recently had an issue with our sendmail where the mail that was being sent to certain corporate users was being bounced as the domain name couldn't be qualified. After much sole searching we provided the server with the fully qualified domain name and all was well. When a user sends a mail to an internal user in our organisation it bounces with a user unknown. It would appear that it is looking for the user on this server now rather than on the exchange server where they reside. We have a smart relay address in the config file to ensure the external mail went out correctly.
As an example we have the entry in the host file as:
1.1.5.72 serverx2 foofighters.com serverx2.ad.foofighters.com
The Smart Relay as:
# "Smart" relay host (may be null)
DSxchange1.ad.foofighters.com
On exchange we have aliases as userx@foo.com where the users email address is ser.x@foofighters.com. Now when the mail is sent to userx@foo.com the server sends ok. If you send to user.x@foofighters.com we get a user unknown.
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 user1@mydomain.com to user2@mydomain.com 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 user1@mydomain.com or user2@mydomain.com (for example), so please tell me what do i do to get the mail.
currently i want to configure sendmail port number 25 im using these port numberalready how can i chage my senmdail port no.
