I'm having a trouble with sendmail on Centos. When I check the maillog, every emails is sent, but when i check my mail browser, it didn't receive the mail. This problem happens with an email address only. (the red email was not received ) This is the maillog

I use sendmail as the MTA for our company. Lately employees have started working from home. These home users send their email through our company MTA using SASL-AUTH. This works fine for the most part but lately we've seen problems with this. The SORBS blacklist looks not only at the IP address of our company's MTA but also at the IP address of our employees home computers. (After all, the home computer IP address is revealed in the mail header.)
SORBS has been rejecting emails sent from our home users because their dynamic IP address is present in the email headers. This is true despite their email passing through our company MTA which is on a properly forward and reverse mapped static IP. The company MTA is not listed in SORBS but the mere presence of a dynamic IP somewhere in the mail header is causing outright rejection. This seems bizarre to me considering home workers sending through a company relay is a common and reasonable business practice.
Can sendmail offer a solution here? For example, to change headers to obscure the IP address of the MUA or make the email appear to have originated directly on the MTA? I don't want to mess with internet RFC but frankly I'm out of ideas for how to get the mail delivered.
I am using webmin for my daily tasks. I have fedora 13, whenever I click on ''Sendmail M4 Configuration'' or Outgoing Addresses (generics)'' I get the following error message
Quote:
The Sendmail M4 configuration base directory /usr/share/sendmail-cf was not found on your system, or is not the correct directory. Maybe it has not been installed (common for packaged installs of Sendmail), or the module config is incorrect. I read documentation at sendmail.org, it seems that structure of directories for send mail has been changed in version sendmail-8.1.4 shipped with FC13. In webmin config module we have
Quote:
Sendmail M4 base directory = /usr/share/sendmail-cf
which is not there. I did a locate / sendmail-cf on the command line, it finds nothing
I recently modified sendmail.cf to use a third party SMTP server to send emails. It works great. But when I run sendmail from the command line, I have to specify the -C flag and force feed it the location of my sendmail.cf, or else it doesn't work.
So in other words, the following works great:
However, if I don't specify the -C flag, sendmail doesn't consider what's in the sendmail.cf and barfs:
I don't run sendmail as a daemon. I'm only using it to send emails. I know my modifications of sendmail.cf are correct because it works perfectly when I use the -C flag. I searched my disk to see if I could find another sendmail.cf on the machine and only the one in /etc/mail came up.
Why sendmail is not reading my sendmail.cf?
I'm running Sendmail version 8.14.2 on Fedora Core 8.
I've recently turned an older PC into a linux box for the purpose of creating an online server with ftp and ssh capability and file sharing. I've installed Kubuntu 9.10 and I'm trying to ssh to the computer from outside the network.I've install the openssh-client and openssh-server and I've created a static ip address, which works fine. I cannot ssh to the machine from outside the isp using either the direct ip address or hostname. The machine is connected to the internet via a Linksys Wireless G router, and I've edited the configuration settings to keep port 22 open for connect in the port server utility.
I've checked the ssh_config and sshd_config settings and port 22 is the default connection port, which is supposed to be open. I've run ifconfig and everything looks fine. I can connect to the computer using a machine connected to the same router, but other computers cannot access it. I want it to be visible to everyone.

now mind you, my linux server is running from port forwarding from my router, which is connected to the main computer, and i have ssh and squid running as well. not sure if those two have any affect on the service. i think this is a problem with the firewall, because i have read somewhere that multiple ports need to be open for a passive ftp to work.

I have a fresh installation of CentOS 5 I'm using for a server, and I'm having issues with port configuration. I have iptables running, and it started with no /etc/sysconfig/iptables file. I added a few basic rules (port 53, port 10000 for webmin), saved the file, and restarted the service. I tried connecting to webmin, scanned ports, and traffic was blocked. I set iptables to allow all traffic and restarted the service, and it still showed basically every port as being blocked. It seems port 80 and port 22 work for some reason, even when I tell iptables to block all ports.
I'm not sure what's going on here. Iptables is reading the /etc/sysconfig/iptables file, and if I use lynx localhost:someport it responds as it should according to the file. However, if I try connecting by IP, it's like there's some other firewall or something running that does whatever it's configured to do.....

I recently setup an email server on Fedora Core (14). Sendmail is running and I am trying to authenticate from a client pc using imaps. I installed Cyrus-imap and it is running and listening on 993. When I try to login, it doesn't accept authentication even though I verified the user's password is correct. (tested with ssh)Is there something I have to do with Cyrus or on the server to allow connections to email? I have not used Cyrus before. I am attempting to access my mail folders via Sendmail and did not make mailboxes in Cyrus. I did allow imaps through the firewall.

I have installed a LAMP server with Postfix as mail server. The scripts send email as user www-data using the mail server on the same machine.
However, the email got rejected by external mail servers (failed reverse DNS check) so I setup a mail server that meets all needed requirements.
Now I would like to use this second server instead of the mail server on the LAMP server. I found that this could be done with changing sendmail settings in php.ini (I think).
However I am not sure how that will go: www-data is no actual user on the new email server (which requires authentication before sending). Do I need to create a new user on the email server or change the settings in php.ini to match an existing user?
I have users [URL] unable to send email to [URL]. [URL] user also unable to send email to [URL]. But both email addresses are fine as they can receive email from others or from [URL] and [URL]. I able to telnet mail server 110 and 25, no problem. Version: ESMTP Sendmail 8.12.10

We're running a sendmail server on a fedora core 9 which we've configured recently. The problem is, the server is working fine but there are some e-mails that enter our server but doesn't get forwarded to the user.

I'm setting up a full server configuration on Fedora, moving it from Mandriva which sadly faces a rather uncertain future. Things are going well and I will be ready (and more familiar with Fedora) in time to upgrade to Fedora 15.
What I have done so far in regard to networking setup:
I first removed Network Manager and replaced it with the network service (chkconfig --level 25 network on). That put an end to the overwriting of /etc/hosts, which now reads simply:
Having some issues setting up sendmail on a (basically) blank RHEL 5.5 server setup. My ultimate goal is to be able to automagically send logs / errors / notifications to ourselves from the server.
Our basic setup is a Win 2003 domain with exchange running on mail.domain.com.au.
I've edited the '/etc/mail/sendmail.mc' and added the :
Code:
line to it.
Also added the domain (domain.com.au) to the '/etc/mail/local-host-names' files
Also edited submit.mc and added
Code:
When I try and send a mail from root or a test user to one of the domain accounts, it seems to go fine, i.e no errors are reported but it never gets delivered.
From the mail logs:
Code:
So it seems to be sent to the queue no problems and when I check the queue :
Code:
Total requests: 0
Not nothing ever gets received. Am I missing something? I have read and read and read but dont seem to be getting any furthur.
So in the end this server doesn't need to do anything except be able to send mail from root to an external mail address.
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've got a server set up with Debian. The problem is that my ISP doesn't allow usage of port 25 (as I understand a lot of ISP's don't).I have PHP scripts hat use the mail() function to send e-mails through the Sendmail application.So, my question is: How can I relay messages sent to sendmail to an external SMTP server (like Google Mail, for example)? Would this be easier to do in the PHP configuration, or on the Sendmail side of things?I've used PEAR extensions in PHP to achieve this before, but scripts downloaded from the Internet generally just use the basic mail() function, and it would be a real pain to modify them all.

View 2 Replies View RelatedI'm having trouble getting my mailertable to work..We have this stupid problem on our internal network where DNS and MX records aren't really set up 100 percent correctly. Getting permission to change it, and test it are way beyond the scope of this question; So I just want sendmail to ignore what's in DNS and fire messages straight to our internal relay server (which works for dozens of other clients) - but it's not doing that. You can see that it's rewriting the addresses to user@www.domain1.com because the parent *.domain1.com is a cname to URL...(someone did this as a poor mans redirect. So if a user tries to go to a subdomain that doesn't exist, they go to the root website instead..
