I have a Nagios box set up on the corporate LAN. I'm trying to get it to send emails to both internal Exchange addresses as well as doing a direct delivery to internet domains.
I have looked at a few logs and it appears that Postfix is not doing proper DNS lookups on the internal servers. It keeps trying to connect to the domain controllers. I have an MX record specified.
Evolution won't connect to our Exchange Server 2003. I have the Evolution-Exchange plugin installed and the Evolution vsn is 2.28.3. The Ubuntu vsn is 10.04 lucid. In the setup of the mail account I enter the user name in the form domainusername; in the OWA URL I enter the URL in the form - URL... and then I click the authenticate button (can't progress without authenticating). When requested I enter the password. Then comes the error message - could not connect to the server. Make sure the url is correct and try again.
I can connect to OWA using a browser. However I have to negotiate past the browser warning me that the server has a self generated certificate and not from a trusted authority. Maybe this is the problem, I don't know. The fact that I can get to OWA by means of a browser means that the firewall in our router is configured correctly, as is port forwarding to the server.The domain/exchange server is in our office and I have administrator rights.
is there any HOWTO for configuring Webmin Postfix server with multiple postfix virtual hosts? Seems to be a tough challenge to set it up without any easy manual..

We use linux mail server as SMTP Gateway we have implemented fetchmail for doing this job. and its MTA is postfix OS is SUSE. Rest users mail are able to come in exchange HUB server via linux mail server. When I see that purticular user X mail in linux I am able see its spool file in /var/spool/mail and also via mail or mutt command. My question is why postix not able to forward that user X mail to our exchange HUB server.

View 3 Replies View RelatedI have postfix setup right now and it's relying mail to our Exchange server fine. What i would like to do though is have postfix save the email that gets passed through so that if a manager deletes an email, it's easy to look through by date and find the email he's looking for. Well, I'm thinking it would be a lot easier then having to need to pull out the backup tape and try to recover one email. Does anyone know whether I would be able to accomplish this?

View 1 Replies View RelatedI'm trying to configure Postfix with a mail server that I programmed in C. The main.cf is set in this way :
Code:
relayhost = [myMailServer.localhost]

disable_dns_lookups=yes
smtp_never_send_ehlo = yes

I don't know why it doesn't receive response after HELO. In fact if I debug my mail server with gdb, I can see it sends a 250 response code. Moreover, I've tested my server both with traditional mail clients, as Thunderbird, and through telnet session and it works very well.
I was following the above guide to get a mail server up and running. The major difference in it all is the fact that my server is running i686, but I compensated for that easily, just a difference in folder/RPM names. [URL]. Otherwise I followed it to a "T." Everything seemed to go smoothly, no trips or falls until the very end.
After installing squirrelmail and trying to login on admin@withfrosted.com returns ERROR:
Connection dropped by IMAP server.
Uncle google tells me to run this command because SELinux is overzealous:
setsebool -P httpd_can_network_connect=1
And that works, and I thought I was home free. However, after that, I'm presented with a new error. However, google told me to send an email to create the mailbox because it wasn't there, yet. So I send a test email on over, but that fails, and so does mailx. Next I created /home/vmail/withfrosted.com/admin while logged into the vmail user for proper permissions. Squirrelmail now logs into the mail box but gives me yet another new error, in which I am now stuck on:
ERROR:
ERROR: Could not complete request.
Query: SELECT "INBOX"
Reason Given: Unable to open this mailbox.
As a summary, because I'm all over the place, here:
1. Can't view the mailbox via Squirrelmail.
2. Can't receive email, tried with mailx and a test email from gmail.
Regarding #2, the gmail test email, from the maillog:

View 1 Replies View RelatedI have a RHEL 4.5 with Postfix 2.2.10 configured as a smart host for an Exchange 2003 server. Its been running well for three years like this. We have some users that are configured with alternate SMTP addresses for a secondary email domain in Exchange. One user is not getting his email for the secondary SMTP. All the others are. After some digging, the maillog indicates Postfix is not relaying his email to Exchange but to the Postfix local mail folder under /var/spool/mail. What in the configuration would cause this? His email is in the relay_recipients file as the others are.
View 1 Replies View RelatedThe scenario: We have an external server that runs HTTP/DB servers for out shop system. Then, there's our local, in-house infrastructure that runs a.. yeah... Exchange 2010. The shop system on the external server needs to send mails to customers (order confirmations, invoices, etc.). seing as sending them directly through the local MTA (Postfix) would cause mail delivery problems because of reverse DNS issues, i've set the Postfix MTA to act as a satellite to our in-house Exchange Server, so the Exchange sends the mail instead, giving recipient mail servers a valid reverse DNS lookup.
Now, mails sent by the (proprietary, uneditable) shop system are relayed correctly and sent to the target e-mail address. My problem is: Mails not sent by the shop system, but by our own PHP scripts which run on that same external servers, are NOT relayed properly. So the Exchange is fine with the mails sent by the shop system, but not the mails sent by our scripts. This is what i get in the mail.log: The successfully relayed mail sent by the shop system:

I am would like to configure postfix to send and receive email across Ethernet (just for now). I have two machines with postfix installed both using Ubuntu 10.04 directly connected with an ethernet cable. I have successfully configured a machine to send email to gmail, however i have been unsuccessful in having these machines send email back and forth. I have been interested in setting up a little mail server at home and have just been trying some simple projects with postfix to start with. At this moment i am using ip addresses and am not concerned with using a dns server
machine A: has a fixed ip of 10.137.202.1, hostname = mail.me.com,
machine B: has a fixed ip of 10.137.202.20, hostname = mail.ubuntu.com
in the /etc/hosts file I map each hostname to ip address receptively (not sure if a good idea, but at this point I have been trying everything)
So I will execute from Machine B
echo "Here is a message" | mail -s 'Hello' cmd@[10.137.202.1]
I currently get from mail.log timed out while receiving the initial server greeting. I get from mail.err valid hostname or network address required in server description #[10.137.202.1]. Obviously when I run the mail command from cmd user i do not receive anything. I can receive mail from myself if from machine A, I sent an email using the command above. I would just like to send email from machine B and receive it on machine A via direct Ethernet connection. I have been through postfix documentation and have also read the postfix definitive guide and have had no luck.
Here is a recent main.cf as I have tried getting this to work (this is for machine A however, similar for B)

However there is something wrong as when i run postfix: service postfix server i get no error but when checking the status:service postfix status i get: master dead but pid file exists Looking into /var/log/mailog i find this line being the issue:

I am switching from Windows Server 2003 to Ubuntu 11.04.
These are two different machines, the Windows Server has 2 2TB Hard drives in it, that are setup as a RAID 1. The data on the drives is irreplaceable. I've scoured the internet for about two weeks, trying to find the best solution. It seems like everyone else had a slightly different setup, or the was no solution.
The Ubuntu Server has a 40GB SSD in it. I just installed a 2TB Hard drive (same make and model of the two in the Windows Server) and made the filesystem for it ext3.
First thing I did was just throw the 2 2TB Hard Drives in the new server, and tried to set them up as a software RAID. After it prompt me to erase the drives, I strayed away from that idea.
My end goal is having Ubuntu machine completely replace the Windows machine, so I'll need to setup Samba (which I'm sure I can figure that part out).
How can I get all the data off the 2TB Hard Drives that are using NTFS onto a RAID in the Ubuntu machine with an ext3 filesystem?
9.10 Ubuntu (Karmic) I could never connect from home using rdesktop, grdp, krdc, etc to the Windows Server 2003 R2 at the office: "Connection reset by peer" or the client simply remains "connecting to...", depending on the client used. Some days I work from home as if I'm sitting in front of my PC at the office.
So I used to boot in Win XP to run mstsc. But the XP partition doesn't boot anymore, no way to fix it, so I need to try the Ubuntu rdp clients.
I even installed a Win XP in a VM (VirtualBox), but now mstsc doesn't connect, it ends due to timeout (as if the Windos Server "knows" I'm not a windows family client)
I wanna do that like this subject. And I don't have any experiences about KVM. Are there any idea about this.

2. Configure the Unix attributes for every user account that will be authenticating from centos.
3. Create an user account to be used as a proxy for ldap, a regular user would be enough. Password never expires.
4. Create a computer account for every centos host; assign this computer account as pre-windows 2000 account.
5. Assign a value of 4128 to the user account control property for the computer account.
