View 6 Replies View RelatedI have ticket tracking software that mails ticket to groups. Right now the software is on an exchange server. After moving it to a dedicated linux server (debian lenny) I cant get it to email any of the internal domain addresses. I have tried to setup sendmail to relay it to the exchange server. Logs indicate that it was sent by the ticket tracking software but the message never hits the mailbox. It also wont get to any other mail address. Is there a better way to do this? The crm software will utilize either a smtp server or any mail server on the localhost. The problem is that with the dedicated server on the same network as the exchange server, it fails to send the mail even if I assign an external smtp server. But if the dedicated server is on a different network then it works using any smtp server in its configuration. I need something that can "pass the email" to the exchange server. Or just be able to send the mail to internal email account and still be on the same network.

View 3 Replies View RelatedI'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 have a CentOS server, and am using Sendmail to relay for various domains. However, I also need to have users send their outgoing mail via this server. I want to have them enter a username and password in Outlook, Thunderbird, etc in their smtp server settings. I currently have this set up via an Exchange server, but I cannot get it to work with Sendmail. I know little about Sendmail, and have done all the config via Webmin, which has worked fine as far as relaying domains. But even though I have added the CentOS user account for the smtp relaying, the clients mail apps give an error saying relaying denied.

View 1 Replies View RelatedWe 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?
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 would like to setup postfix to act as a relay for the outgoing mails of a couple of servers each serving it's own domain.The mails we are talking about are standard administrative emails like user registration, password reset request. The volume of those mails will naturally grow as the site grows. Which for me poses the problem that depending on the growth of the site you will sooner or later hit the quotas imposed by (my otherwise preferred) providers like GMail or smtp.com.
So what I need is a mail relay that will only accept mails from authenticated clients from hosts in its access list and relay their mail without restrictions. Is that possible with postfix? What has to be changed in the config and what are the pitfalls?
I'm trying to set up a simple local email service on a small office client-server network. Can I use sendmail without setting up a separate DNS server. If I need a DNS server can I set it up on the same computer as my sendmail MTA? Can it be a private DNS server?

At the moment i am using a windows environment with exchangepop3 which uses smarthost to connect to the ISP smtp server. Please help or point to a simple guide. If i cannot solve this soon i will have to revert to microsoft solution for the proxy server.

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

View 7 Replies View RelatedI want to setup sendmail using my username and password on my ISP to be able to send out messages.This is actually true as the mylocaldomain is not a public Internet domain.

View 1 Replies View RelatedI 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 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.
