Ubuntu Servers :: Postfix Not Sending Emails?
Jan 18, 2010
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 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.

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 have wordpress installed on my VPS, which is running 10.04.1 LTS. I appear to be having an issue whereby the server isn't sending out emails to new users, nor to myself when I get comments on the blog.I'm at a dead end for where to look next, because the settings are exactly the same as they were with my previous VPS (and they were always pretty generic), but yet it doesn't work.

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 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'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 have an rsync backup job scripted and run by cron at 12:00 every day. It emails me the log from rsync. The problem is that it sends the same email every minute starting at 12:00 and ending at 1:00. I can't figure out what I did to cause this. It is not happening on my other ubuntu server.
Code:
# m h dom mon dow command
* 12 * * 1,2,3,4,5 /home/barry/bin/backup.sh > /dev/null
Code:
#!/bin/sh
rsync -aut /usr/share/library /mnt/backup/WordPress > /home/barry/backup.log

When I am using Mailutils to send messages to myself as a test, I get them but they are from <"ryandward@ryandward"@gmail.com> which is not a valid email address and I have no idea why my system is configured to send them from this address. This is indicative of some problem there is going on in my system.

i've got Evolution as an email client in Fedora 12.ve got only one IMAP account configured, which seems to be working OK. However, temporarily it is not sending emails. I write an email and hit send/receive and get error. "Error while sending message" ir seems that it is downloading messages, but not sending. There is a quick, but annoying solution to it: restart Evolution. As soon as it is restarted (close and ope the application) it is working OK for some time.

I have installed Ubuntu onto a machine and am trying to get it to receive fax's and email them to me! After spending days on this I have installed efax-gtk and have successfully set it up to receive fax's and email them to me!
Everything is working, I can send and receive fax's ok, But when I set it with the 'mail_fax' script, I dont get an attached file, All I get is a directory location of the temp file, Witch is obviously deleted by the 'mail_fax' script! No Attachment is in the email.
/home/dell/efax-gtk-20101103135335.pdf
Fax 20101103135335 received by efax-gtk attached
All I want is the attachment to be attached!

Heres my logwatch.conf file:

I just got control over a server that was hacked several months back. The other day we started receiving rejected emails sent from my server to a yahoo email address that is no longer active that contained users login information. I am trying to find the process that is sending these emails. So far its been like finding a needle in a haystack. The email that is being sent is appending the login information each time it is sent so there must be a local file that contains this information. I have tried using grep and find without any luck.

I have a 64bit linux server with 5 virtual hosts on it. When someone fills out a contact form on one of the sites...I get 15-20 copies of the same email. At first I thought it was the kids clicking send multiple times because the first emails were coming from the children's ministry "Email The Cast" section. But then I started getting multiples from the adult sites too. All contact forms are set to come to me.
What's stranger is that my registration section for one of the sites uses the SAME php script (different file) to email me a notification that someone has registered but I only get 1 copy of that.

Since we switched our server to Squeeze, I'm receiving emails from the cron about a mysql error (...can't use locks with log tables). But this is not the issue I want to talk about here. The issue is that since the executed command is: /usr/bin/mysqlcheck -uroot -pmypassword --all-databases --check-only-changed --silent which is a command that was automatically added to the cron by the mysql package (I believe), the password is sent in clear text in the email's subject. In my sense, this is a serious security issue (sending root password in email subject...)
I don't know at what level it should be corrected, but it seems to me like it should be corrected in the Debian distrib, shouldn't it ?
And for now, how can I hide the password in the emails I receive ?

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!
# 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. The Debian default

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.
