Debian Configuration :: Postfix - Dovecot Configuration
May 13, 2010
I have a web server running and wish to get a mail server running on the same machine. I have a registered domain name. I have postfix and dovecot installed. I can send emails from the server to my normal address on a different domain but cannot receive mail. I can send and receive mail locally with no problems. I just don't know where to look for the problems. If you need any more info ( config files/doamin names etc let me know)

Delivery via docevot lda works for the virtual users.
Sending a mail that should be redirected to a folder instead of going to the INBOX does not work
Code: Select allecho "lala" | mail -s beispiel julius@myvirtualdomain
#/home/vmail/julius@myvirtualdomain/.dovecot.sieve
Code: Select all
require "fileinto";
if header :contains "subject" ["beispiel"] {
fileinto "beispielordner";
} else {
# The rest goes into INBOX
# default is "implicit keep", we do it explicitly here
keep;
}
I can see no errors in dovecot.log, -info.log, -debug.log but also no sieve messages
Code:
Select all
#/etc/dovecot/conf.d/15-lda.conf
protocol lda {
postmaster_address = julius@localhost
mail_plugins = $mail_plugins sieve
[Code] .....

I have currently configured Postfix as an SMTP server. I would preferably not use a domain name in my email address, like so: myname@[1.2.3.4]
I'm currently testing to see how other mail servers handle this kind of address. When I sent a mail with one one of my gmail accounts, I see that the mail gets rejected due to bad syntax.
It seems as though Google is giving me a RCPT TO address like so: myname@1.2.3.4 However, the postfix server rejects this address with the following error:
501 5.1.3 Bad recipient address syntax
To my best knowledge the only way to have an IP address inside an email address with to write it as a domain literal [1.2.3.4].
My question: how to configure postfix to accept myname@1.2.3.4 as well?
I have put both [1.2.3.4] and 1.2.3.4 in "mydestination" and 1.2.3.4 in "virtual_alias_domains".
It doesn't seem to work so far though.

My Postfix cannot currently create any folders other than inbox. Even when I send an e-mail I receive an error along the lines of, "Could not create sendmail folder." Also, my Postfix isn't receiving e-mails, and can only send e-mails to other accounts on the server. I called my ISP and they told me my port 25 isn't blocked, and it is forwarded on my router so I am not sure what could be wrong. I am using zoneedit as my name server and I am pretty sure my MX record is good.

i created a second instance of postfix.It isn' t the first time that i made this procedure but with debian i had a lot of problem.I think that the problem is chroot configuration of postfix .In the first i had two problem smtp “fatal: unknown service: smtp/tcp” and the second instance was enable to make nslookup of domain.I copied the necessary file in /var/spool/postfix-second-instace and i solved the errors.Now the problem is that there aren't error in log file but connect to xxx.xxx.net[yyy.nn.yyy.yyy]:25: Connection timed out for all connection. and the email are all in defer directory and the second instance doesn' t send emails.

The problem I have is so simple yet difficult for me to resolve. My Postfix MTA allow fake mails from me@example.com to me@example.com. How can I block them?
For example, if I do "telnet smtp.mail.yahoo.it 25", as I write the MAIL FROM command I get the alert "Authentication required". How can I achieve that?

I did search the forum but didn't find an answer.
I have setup Postfix + Dovecot on my basic debian 5 server. If I send a message to a localuser@mydomain.com from mutt, it delivers just fine and is visible when viewed through squirrelmail, I can also send just fine.
My issue is that irrespective of what options I set in main.cf, I cannot for the life of me get Postfix to stop erroring with "Recipient address rejected: User unknown in virtual alias table". I'm stumped.
My main.cf is as follows code...
I do not want to setup virtual hosting with MySQL or similar, I literally want to receive mail in local users mailboxes for a single domain. Any ideas on what's missing?

For long-term migration from courier to dovecot I would like to install courier-pop and dovecot-pop3d simultaneously. Aptitude offers me to install one, by removing the other, only. Can this be done without creating problems for the package manager and future upgrades? And why if not?
The following NEW packages will be installed:

I'm doing some tests and playing around with postfix in a test squeeze server. What I want to achieve is a postfix mail server using ports 465 and 587 with smtp authentication to send mails. I followed this howto: [URL].. and I'm using a php script with pear functions to test sending emails to a gmail test account of mine. This is the script:
<?php
require_once "Mail.php";
$from = "Webmaster <webmaster@server>";
$to = "My Name <myaccount@gmail.com>";
$subject = "This is sent with pear as a test";
$body = "This is the body of the message";

I am having no luck configuring ProFTPd on a Debian Lenny production server we use to host our MySQL databases and a few websites. I had originally set it up so I could login and manage our internal sites, but I have the need to allow a few clients in to access their sites that we host. I am trying to root the users in their site directory, which would be "/sites/www.whatever.com/".
It just hit me while typing this. Is it possible to create a user without a shell to prevent login via SSH and set the home folder to /sites/whatever instead of /home/username? That would allow me to continue operating with my current configuration and root them in their site while preventing SSH logins.

i have a HP MSA 2312fc SAN with 2 LUNs configured. The first LUN (LUN ID 1) is correctly connected to the system, but when i connect the second LUN (LUN ID 30), i find in the syslog this message: multipathd: 8:64: size 6835937472, expected 5267578112. Discard
Here is the multipath.conf
[Code]....
So I correctly see the two luns, but multipath doesn't create the relative devices. Under /dev/mapper I see: control mpath0 mpath0-part1 mpath0-part1 is the first lun, the one I mounted in a directory under filesystem. I can't find the device for the second lun

I am *finally* getting around to rebuilding my file-sharing computer. I'll be sharing files with both Linux and Windoze machines. It's a home network, so there's nothing fancy needed. I know I have to tweak my smb.conf file until I'm satisfied with the features and security. I'm using SWAT and I'm starting with a bare-bones conf file. It's not secure but I can see the server and selected files/directories from my other Linux box.
My really dumb question is, do I have to reboot both the server and the client machines every time I change the SAMBA configuration? I thought I just had to stop and restart the SAMBA service in the SWAT software - but then the server disappears from my client. It looks like I need to reboot both machines for the client to see the server.

I have a PC104 running debian. I have 3 hard drives (in addition to the one booting) mounted in fstab by UUID. I use the options defaults,error=remount-ro. However, this means that when I boot with the hard drives not attached, I have to press Ctrl-D to bypass when the boot discovers the drives are missing. Is there a timeout commandoption I can add to fstab so that it automatically continues booting even if the hard drives are not attached? I could not find anything on a timeout command. (I tried adding timeout=1000 but no-random guess)

I am using Squessze and Gnome. When I try to use the gui System>Administration>Network or Users and Groups I get the error The configuration could not be loaded. You are not allowed to access the system configuration.Everything was working before. I read around a bit. In some cases,it was caused by mismatching group and password files after using the gui. I do not know how to check if they are matching. Of course I do not know for sure that is the problem in my case.

I am working on a Debian 2.6.26-19 Distribution with exim4 as MTA. After a system restart a problem occurred with delivering emails to local addresses. These local addresses use a 1and1 mailserver for email. The MX records for the local domain are set correctly but exim does not use a DNS lookup for these addresses because it identifies them as local addresses. I figured this out by executing the exim4 -d -bt command. The dns lookup part of the result looks like this (I replaced the actual address with placeholders):
[Code]....
The eventual result of the exim4 -d -bt command is: [user]@[domain.ext] is undeliverable: Unrouteable address How can I make sure, that exim4 makes a DNS lookup for the local addresses instead of skipping it? I know that I have to edit a exim4 configuration file, but I could not figure out which and how.

I have a set of vm's with stable, testing, and sid to keep track of how things are going. When I did an apt-get dist-upgrade with squeeze last week, things seemed to OK (350 package updates) until the end. It didn't seem to like and / or was confused by a kernel dependency.
I am not too concerned yet. Because these are in vm's, I do a snapshot before any significant change. I can futz around with impunity because I have that backup.
I re-booted, and tried the apt-get dist-upgrade again with same results. I think I also tried apt-get -f install.
So I reverted to the snapshot, and will simply try again in the future. I recall that with lenny as testing, the font-desktop was really screwed up for about a period of 6 weeks.
However, just in case someone else runs into this:
1) a re-boot worked, but the failure of apt-get made me nervous enough to revert.
2) waiting for corrections has seemed to work in the past (with a single exception with a 4-disk SCSI software RAID10 update that failed to re-boot lenny successfully after what seemed to be a minor update -- that was on a real system, not a vm. I haven't gotten back to look at that.)

I recently just installed Squeeze on an ia64 system and was having some troubles with running VNC.I get the following error, more specifically for some reason I get a malloc - memory corruption error:

After display all the code above, it just stops. The port 5901 is still closed - if it runs properly, would it open automatically?Is there something that is incompatible? Or am I missing some system configuration component?

I have a postfix server running on a virtual machine hosted by vpslink.com. I have followed the following configuration guide to install the system with dovecot, sasl smtpd authentication, and postfix as an mta: [URL](I know it says it's a debian configuration, but it seemed legitimate that I could follow it). Anyway, in sending email from my primary email account, I have found that roughly 1/2 of the messages are delivered, and 1/2 of them are rejected with a message similar to the following:

I'm running Postfix primarily as a local email server. There is no email coming in from other machines, and there are no other machines using it to send mail. But I'd like it to be able to send mail. I use Evolution for my normal email stuff, and it's configured to send mail to my ISP's smtp server, and that's working fine. But I occasionally send mail from the command line, using the "mail" or "mutt" utilities. (Mutt because the standard mail doesn't support attachments.) These don't use Evolution's configuration, they depend upon whatever is listening to port 25 - and that's Postfix. So all I should need to do is to give Postfix the smtp server, user name, and password. My problem is that Postfix has voluminous documentation online, and I haven't been able to find this simple configuration in it.

I have configured postfix on my server.
telnet mydomain.com 25
helo validdomain.com
mail from: validaddress@validdomain.com
rcpt to: validuser@mydomain.com
[code]....
When I run this test, as expected, the email is delivered to validuser. However, postfix also delivers it to user1 and user2 despite the fact that the sender does not belong to my domain. I have implemented client, helo and recipient restrictions as below. How do I prevent the malicious use of CC as described here?
Snap of main.cf
-------------------
smtpd_client_restrictions = permit_mynetworks,
reject_invalid_hostname,
reject_rbl_client zen.spamhaus.org,
reject_unknown_client,
