General :: Nagios3, Postfix: All Notification Emails Go To Root?
Aug 10, 2011
I have nagios and postfix on the same ubuntu box.Postfix is able to send emails out as root and my user id to my gmail acct, but not as user nagios, which does own the nagios process. I haven't been able to find a way to authorize user nagios to send email (really), but I don't know if this is the underlying issue. Frankly I don't care what acct they originate from as long as they arrive.Currently, all notification emails are being dumped locally into root's mailbox. There are no errors in either the nagios.log or the mail.log.I've added my gmail address to the contacts.cfg, replaced it in the nagios.cfg, and put it every other place I could find root's mailbox mentioned. I've also created an alias for root to my gmail acct with no luck (didn't want to do that fearing I'd receive emails for other system events, but it didn't work anyway)

I have a CentOS 5.3 system running a recently installed Postfix (I removed sendmail so I positively know it's running Postfix).
I am able to send out email as user root, but when I change to another user on the same server, the mail delivery fails.
Here's what's captured in the /var/log/maillog:
Here's my main.cf
No changes to other Postfix files since install, so they are the default files.

I am trying to find a way to tell postfix to forward all emails from
dbsupport@thisdomain.com
and
helpdesk@thisdomain.com
to
be sent to admins@thatdomain.com, but it is not working. I am trying transport maps. The content of my transport file is:
Quote:
helpdesk@thisdomain.com smtp:admins@thatdomain.com
Quote:
dbsupport@thisdomain.com smtp:admins@thatdomain.com
Both [URL] and [URL] are on box1 as an alias in the /etc/alias file like this:
root: helpdesk@thisdomain.com
root: dbsupport@thisdomain.com
how to get this working?

Running Postfix 2.6.1 on Slackware 13.0.I noticed that if I send an email with a large attachment(namely more than 500 KB) from another computer using this postfix server as an smtp server, it takes up to an hour to send it.It's almost like postfix is configured to send large emails later with a lower priority.The client computer and postfix server are within a GIGABIT LAN so upload 500 KB isn't an issue.

I have a problem with my VPS not being able to send any emails to Yahoo! addresses. Each time someone with a mail account tries to send something to a Yahoo! address, the email stays stuck in the mail queue and a 'delayed mail (still trying)' message is sent back to the user. I understand that Yahoo! has a tendency to block mail servers on a whim, but what I'd like to know is, how can I prevent Postfix from specifically retrying to send emails to Yahoo! mail servers? I don't want to stop retries to other mail servers.

how to get this working? I mean have an icon in the tray alerting of new emails. I used to have it working using moztraybiff [URL] in Thunderbird 2, but since I installed F11 and thus started using Thunderbird 3 I haven't been able to get this working. (Evolution, on the other hand, has this and it works fine, but I'm having trouble, [URL], with using Google calendars in it. If I could get that working I would think about switching to Evolution).

I run Ubuntu with Unity. I see a Mail Notification applet in the tray that announces unread mail (from Evolution) and incoming IMs from Empathy. I uninstalled both programs, and replaced the IM program with Pidgin. (I don't have a preferred email client yet.)
Now Pidgin lets me know whether I have received new email messages from the services it is connected to. These notifications show up in the Buddy List window. Is there a way to get Pidgin to use the Mail Notification applet instead? I read in their site that "Pidgin was not designed to be an email client" but it would seem that all the pieces are in place to reroute those notifications to the mail notification applet.
Optionally, it would also be cool if when I clicked on those notifications, a browser window would open up to the webmail account the notification came from. (I have both Windows Live and Gmail accounts.)

i'm not a techie but have tried my best to solve the issue without success. I have a static IP from local ISP and my computer is configured with 192.168.1.2 (LAN IP).
I have installed ubuntu server 9.04 and want to send emails from my server for which I've configured postfix. But I dont know what to do next.
My questions are:
1. Do i need to install DNS server for using postfix? If not, what should I install to send emails from this server?
2. Do I need to forward any particular port in my router?
3. If I dont have a fully qualified domain, what are the configurations I need to do to send emails?

I'm stuck with postfix. It cannot send emails and I cannot find out why! smtpPort 25/tcp is open. I can telnet localhost with 25, but not the localhosts IP(192.168.1.15). Sendmail is OFF. Here is the main.cf file!
# See /usr/share/postfix/main.cf.dist for a commented, more complete version
# Debian specific: Specifying a file name will cause the first

We have a number of servers at work, some production and some non-production. We run some java applications on these servers. At present these java applications send emails via an SMTP connection to our live email servers.
In production all is well, the java apps send emails to customers. However, in the non-production environments all emails must not be sent out. Instead they must end up in some kind of generic inbox.
We don't want to mess with the production setup at all and it isn't an option to lose the non-prod emails altogether. So on non-prod we can reference another SMTP server and send all emails there. So far I've set up a postfix, dovecot, squirrelmail email server which appears to work.
how do I config my new email server so that any emails sent from our non-prod server to fred@hotmail.com, bill@yahoo.com, jenny@gmail.com etc all end up in one inbox?

One of our postfix servers is for sending/receiving internal emails only. When a user entered a wrong recipient address, it will take almost an hour for the user to get the "Recipient address rejected" email. What can be done to let the user get the "Recipient address rejected" email quickier.

I'm building a replacement postfix email server and I'm getting intermittant loss of sent emails; where: sometimes mail ends up at the recipient (a hotmail address) and sometimes not. Having an offsite relay (or posting directly to the internet) doesnt help either. (Although using hotmail itself as a relay always works despite logged complaints about unchecked ssl certs) Most dissapointingly the log files for the smtp transations are the same for successfully received emails as for the "lost" emails.

biff = no

I've recently followed a guide I found online [1] and installed Postfix and Courier on my server machine. I can send emails from the server to any email address but unfortunately I can only receive emails sent from the server - it's only accepting emails sent locally from the host.

I've been banging my head against the screen on this strange problem. Somehow my server sends out spam mails to a lot of aol mail addressess. The mail.log file looks like:

I've been looking for a way to filter out emails on my postfix server by GeoIP data. I couldn't find anything that fitted the bill so wrote my own in Python as a postfix policy. Thought I'd post it here to see if it's of any use to anyone else. I've attached a tar of the files as the Python formatting will get mucked up by the forum code. Comments/improvements are welcome (be kind ) First file is : policyd-geoip which is owned by root:root and placed in /usr/bin with 755 perms

I got a weird postfix setup question? This is a separate server to the one I posted about earlier today.
I need to setup a postfix server which will accept emails for local know address (full addresses) and deliver them straight to the users maildir.
Any unknown addresses (however for the same domain), needs to be relayed to another server.
This is a bit of a special setup as there is no fixed Internet connection to the server. So the plan is that local email get delivered straight away whilst emails to the same @domain, but that doesn't exist in the user tables get put in the hold queue and is later relayed to server number 2 when a connection is available.
I am using mysql to retrieve all my settings into postfix.

How would one setup a header_check that would discard all emails that have more than 6 words in it? Such as, if there are more than 6 spaces in the entire message it would be deleted? I cannot find this out but it would reduce my spam intake by 50+ a day.

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 user@mydomain.biz 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 main.cf. I am running ubuntu 9.10.# See /usr/share/postfix/main.cf.dist 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.
