Ubuntu Servers :: Postfix - Bogus Emails From Unknown Users Sent?
Dec 2, 2010
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:
Code:
Dec 2 16:10:55 Ubuntu-904-jaunty-64-minimal postfix/qmgr[7685]: E95C2B48DB4: from=<HappyShopping@somedomain.nl>, size=1912, nrcpt=1 (queue active)

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?

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?

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 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.

I tried searching the posts and have come up empty handed. I need to find an email I sent to myself (actually a forward of several other emails) that did not get delivered. Otherwise I need the original emails themselves. I have been using pop with dovecot on my ubuntu server Jaunty machine. I searched the mail logs and found that the reason the message might not have been delivered could be because my permissions were not set to administrator for that user. I changed the permissions and still nothing came back.
I deleted the client mail account on the machine I used that had the messages but I was hoping they might still be somewhere on the server. Any ideas?

I'm just getting started with postfix for the first time (using courier pop) and everything is working well. However I can't seem to figure out how to only allow some system users to have mailboxes?
For example I have a few accounts which are FTP only accounts but they still have mailboxes under postfix? Is there any way to tell postfix the accounts that I actually want mailboxes for?
Also on a side note, I notice that mail seems to be stored under the user's home directory. I'm scared they may accidentally delete them.

Alright I have read through and tried many different tutorials but a VAST majority of them are with virtual users. This is my own personal email server so virtual users is unneccessary when I can just use the users personal mailbox.
My postfix main.cf there are 2 things I am unsure of. 1) For system users which local_recipiant_maps do i use? 2) What should mynetworks be?As I have been testing it out through telnet I can send mail but it doesnt get to my test email (a gmail account) and when i try to send an email locally it seems that everything works fine but the mail doesnt get there, and the error i am getting is that it cant find the user.

I have a mail server running Postfix and the problem I'm running into is that when trying to send mail, I get a "relay access denied" error.Inside my main.cf, I did not specify 'smtpd_recipient_restrictions' so by default, the variable is:
Code:
smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination
The 'mynetworks' variable looks like this:

I followed this tutorial to setup a mail server, followed it to the letter, double/triple/quadruple checked everything for human error, and I can't find anything.[URL].. What's happening is it seems that postfix is adding a trailing slash to usernames when it does the user lookup, so they don't exist and then fail. I've attached the log below.
Code:
May 11 01:06:27 vmail postfix/smtpd[1688]: connect from localhost[127.0.0.1]
May 11 01:06:55 vmail postfix/smtpd[1688]: 3372E982BC: client=localhost[127.0.0.1]

I've set up an email server as per this howto: [url]
In a nutshell, it uses a combinatio of postfix, dovecot, amavis (ClamAV and SpamAssisan) and mysql.
However, with this setup, authenticated users are able to spoof outgoing message by simple changing the "from" tag.
Does anyone have any ideas on how I could implement some address mapping to users?
In this setup, postfix users are NOT system users, by are stored in the database.

make install then i got this error: postfix: fatal: chdir(/usr/libexec/postfix): No such file or directory make: *** [install] Error 1 I don't understand why it's checking the usr/libexec folder for the daemons although I've set the folder to /opt/product/postfix-2.6.5/libexec in the makefile.

I recently moved over user from an old box running postfix(v 2.0.16) over to rhel 6 running postfix (v mail_version = 2.6.6). ive tried to make sure all the files are of correct permissions and that the main.cf file is configured corectly. 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:
Feb 25 16:24:39 puny1 postfix/master[3517]: fatal: fifo_listen: create fifo public/pickup: Permission denied
I gather this is a file permission issue and ive tried to make sure the public folder in /var/spool/postfix is correctly set but still no avail.

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?

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!

I am using the Postfix SMTP server for sending emails. However I just did a default installation and subsequently someone is sending spam using my SMTP server. I would like some help on securing my Postfix server and to block these mischievous emails being sent from my server.

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 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 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)
