Ubuntu Servers :: Postfix Adds Trailing Slash To Users?
May 11, 2011
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]
May 11 01:07:18 vmail postfix/cleanup[1691]: 3372E982BC: message-

On SUSE 11.2 when a CD or DVD is automounted (in the /media directory) it appears that the mount point chosen for the disk always has extra blanks at the end of the mount.
For example, if the label on the CD was DISK-001, the mount point chosen by SUSE is
/media/DISK-001 /
In 11.1 (and earlier) the mount point would have been
/media/DISK-001/
I'm assuming that the trailing blanks are filling in unused or blank chars at the end of the CD label.
Is there any way to change this annoying behavior? I much prefer NOT to have trailing blanks in the mount point.

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'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:

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'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.

I have an issue with postfix and my server.One account (mine) is not considered as spam by no one. But all the other users are treated as spam by yahoo, and hotmail. And I can't understand why.Here are the header from one user who sent an email to my yahoo account (treated as spam):
Code:

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'm thinking of a few ways to do this I'm curious how many better/equal ways there are to do the same task.in a file with format like: 20 text Gi0/2 some other junk I have it reformatted to look like this before going in a database: 0/2 20 text. But for whatever reason some of the new input text looks like this now: 20 text Gi1/0/2 some other junk
My script makes it look like this: 1/0/2 20 text. I want it to remove the leading number and slash if the input file is in the new format.

If I want to add Windows & Mac users as Samba users, must I first add them all as Ubuntu users? If so, since none of the other users will actually be working on the Ubuntu Server, how do I disable the other non-admin users on the Ubuntu Server login screen. I am using Webmin to administer some server settings, and command line for others.

After upgrading from a working 9.10 system to 10.04 Postfix has stopped delivery email to users. Sending email is fine and IMAP(s) and POP are working fine but receiving messages now get the follwing message
postfix/pipe[14331]: 65B941B61F0: to=<me@fred.com>, relay=dovecot, delay=1081, delays=1081/0.02/0/0.1, dsn=4.3.0, status=deferred (temporary failure) Using Postfix with Dovecot, MySQL & Amavis plus spamassasin
Does anyone have any idea what the upgrade process may of changed in the upgrade none of the conf file were replaced during the upgrade and only one parameter caused a issue for Dovecot after the upgrade "ssl_disable = no" after disabling this dovecot started

I want to change all outgoing email from my Ubuntu server running postfix to change (masquerade) the username. eg. james@example.com will appear as 'From' 'admin@example.com'. I already know how to masquerade domains, but not users.

i am trying to set up a mail server that will support users in a LAN in my school. I am using postfix on a Mandrakelinux distro.
I can send mail when I am root to the other user on my (same) machine both when in command line (mail command) and on Graphical mail client (Kmail ) but the user (sam) cannot send mail to the root account on either interfaces.
I followed the postfix configuration settings on John_Wiley_-_Redhat_Linux_Networking_and_System_Administration_3rd_Edition.

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?

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:

the preceding and trailing spaces around the commas in my CSV without destroying my address field. I'm new to regex and sed so this is probably easy but I just can't do it without destroying the Address section. I'm using vanilla Linux and sed 4.1.3I'm willing to use any regex or even awk if needed.
Example:

I came to debian from fedora so there I used ( su - ) to become root user. So my question is that in debian, is it same using ( su ) and ( su - ) or here also using ( su - ) is preferred with slash or without slash. What is the correct and secure way in debian with full root status.
One more question relating gedit sources.list
I use as root account : gedit /etc/apt/sources.list (and then enter and sources file in gedit open)
Is this correct method or any other way as when save after changing entries inside it says error.

I have a back-end server behind a proxy machine. I would like non-SSL requests to the proxy to be rewritten into HTTPS requests to the back-end server, while not screwing up URLs with missing or misplaced trailing URL slashes. So far, on the proxy side, I have this in a virtual host for port 80:
Code:
ReWriteEngine On
# trailing slash fix:
RewriteCond %{SERVER_NAME} my.proxy.com$ [NC]
RewriteCond %{REQUEST_FILENAME} -d
[Code]...
But adding anything else to the URL fails, as the back-end server name gets stuck into the proxied [URL]... The rewrite log seems okay, I think. So I guess this is failing at the reverse proxy rule? Where am I going wrong?
