Server :: Postfix + Courier + Squirrelmail Tutorial - Can't Get Into Mailbox
Jan 1, 2010
i followed this tutorial to the "T", [URL]. I am not able to login to the mailboxes with squirrelmail, it says "connection dropped by imap server" I used the whole address as a login just like it said to do. I can sucessfully authenticate with outlook express but it throws an error that say's [URL], no such file or directory. i can telnet into it remotely but when i type ehlo [URL] it just keeps showing all the 250 lines and wont let me generate a message.
from what i saw on the comments on the tutorial and googling there are many other people with this problem, however i found no solutions. This is fresh work and i have not touched any config files since finishing the tutorial

I have setup a postfix + courier + squirrelmail email configuration. I can get to the squirrelmail login page and run its test and it said everything was fine. After that I am stuck. What is the username and password or if it is not created, how do I create it?

I'm looking into migrating postfix mailboxes and users from an old machine running Fedora5 to a new machine running cenOS. I was wondering, what would be the procedure to migrating over existing postfix mail to the new machine? Is it as simple as copying over /home directories and /etc/passwd etc?

In the last week email delivery had slowed down to taking approximately 24 hours and investigation has revealed that there were 45000 emails in the mailqueue. I flushed the mailqueue yesterday but mail delivery is slowing down again because emails are again being queued by the thousand.
The mails are mainly spam sent to ficticious users at a genuine domain hosted on the server.
My setup is running Courier IMAP with Postfix, Spassassin is installed along with Amavisd-new but I just don't understand why this has suddenly become a problem based on my setup not having changed for the last 6 months.
Should these spam emails be being discarded by spamassassin before reaching the mail queue? Are my discard score settings too high (6.9)?

I'm trying to get my server back up to snuff. I'm using Debian Squeeze right now and I'm up and atom with apache, mysql, php, pureftpd, ssh, and I have squirrelmail installed.
My dilemma comes with the mail part of the whole ordeal, Postfix and Courier are installed, have their keys made, and for what I assume, are configured correctly. HOW do I make new virtual users? My domain points to this machine as well as my MX record for mail.mydomain.com.
I need IMAP and POP working. And upon the creation of new email users, will SquirrelMail interface with Postfix and Courier? When I installed SM I set it up for use with Courier.

I'm running Postfix in slackware 12.1. The mails are stored in /var/spool/mail/username. When a user's mailbox size got more than 200MB, the user can't check their mail. when it happend the log shows:

running squirrelmail, postfix and dovecot, I filter out mails which are spam into a spambox and non-spam into the inbox but by default, the user is not subscribed to the spambox and therefore, the spambox is not visible to the user, how can I make it such that each time a user is created he or she is automatically subscribed to the spambox?

My company email server has been working flawlessly for the last 5+ years. Recently, one of our clients put their email server behind a firewall (an assumption on my part; details below). Ever since, email sent from within the company (192.168.xxx.xxx internal address; all computers and server is behind a NAT firewall [Netgear FVX538]) is either being sent to the client after some delay (if email is sent using Outlook) or is being deferred until the messages expire (Thunderbird, Squirrelmail, etc.). Email sent to the client from anywhere outside the company (using Thunderbird, Outlook or any other email client) is also delivered without any problems (usually after a short delay).
All other emails to the World are being sent without any problems at all (both inside and outside the company; using any email client or webmail). I did contact the client's postmaster, but the client, being a large government agency, will probably not address the problem (if it is on their side) anytime soon. I am not sure if I can do anything from my end to solve the problem. Ever since the problem with the client began, I added two statements to the postfix configuration file (smtp_pix_workaround_delay_time = 20s and smtp_pix_workaround_threshold_time = 0s); this seemed to a bit - it reduced the delay for emails sent via Outlook to a few minutes (as opposed to 30+ minutes); emails sent using Thunderbird/webmail are still being deferred.
Server details: Dual quad-core processor machine, 32 GB RAM, dual 1 gbps network, running Fedora 14 (64-bit; loosely modeled along the lines of Perfect Server (with ISPConfig2) as described on the howtoforge website). Running Postfix (v. 2.7.1), Dovecot (v. 2.0.9).
Postfix details:
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
body_checks = regexp:/etc/postfix/mbl-body-deny
broken_sasl_auth_clients = yes
command_directory = /usr/sbin
[code]....
I emailed the client's postmaster suggesting they disable smtp fixup. But still, what bothers me now is that Outlook works (both within and outside the company) while Thunderbird, webmail, etc. (used by ~90% of the users) do not. In addition, all email clients from outside the company can send email (authenticated via the company server) to the client without any problems. Is there anything I can do on my end to make non-Outlook clients work within the company (webmail is hosted on the company server; so, it would have an internal address as well)?

I have a Linux server that has local mail service. There are few user accounts on this server. User may send the mail to each other but that only restrict to LAN environment only.
For example, I may
# mail user1
To send mail to user1. User are not able to send mail to public. Some service like hylafax using this local mail service to send notification of fax status.
I don't want to manage and maintain local mail service anymore. I have subscribed a package from ISP to host a public domain of my own. I wish to have my hylafax service to able to send the notification mails to public mail server, is that possible to do it? It is great if all mails that send to local mail server may forward to public mail server. That makes the local mail service serve mail forward only.

I have installed qmail on my 10.04 server (Because I prefer qmail and dont want to use postfix) and I would like to just install courier IMAP/POP server without the Postfix (Or other mail servers).
Is there an apt-get install switch that will install just what I want to install without deps; or at least a way to block unwanted deps from being installed.

I can send emails to local accounts but not out to the world. Here are the refrences I used to set things up.
[URL]
I was able to send and receive after the "basic" setup. I added amavis-new and I am pretty sure that it stopped working then. (late nights, lots of changes/tries not 100% sure any more) Went back to basics trying to send a test email from telnet (on the server).
Code:
mail:~# telnet mail.my-server.com 25
Trying 216.240.35.89...
Connected to mail.my-server.com.

EDIT: Change the topic, see post #3
I've been following this guide: http://flurdy.com/docs/postfix/
And done the points up to "Advanced mail server" and are trying to test mailing mail@mydomain.com to mail@mydomain.com (yes, the same inbox) using Thunderbird, through my own DNS, from the server.
But I get the following error: The message can not be sent because the connection to SMTP server mydomain.com timed out.
And when I check /var/spool/mail/virtual where the mailboxes are supposed to be stored there are none.
So I'm wondering how I create a mailbox with postfix.
I can add that I am quite a noob at linux but have to do this in a school project.
I'm using ubuntu server 10.04 32bit with GUI (yes I know, I know)

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.

I am currently running Ubuntu Server 9.10 and followed this HOWTO on setting up my email server.
[url]
Everything seems to work correctly. If I look in the Maildir the emails I send to test are there.
The problem is when I try to sync my email via IMAP from my windows box (on a different network) it doesn't show any of my email nor does it deliver new email. My email app doesn't give any errors nor does the logs on the server.
How can I get it so my email syncs to windows computer? I am sure it is something really small that I am over looking but I can't seem to find it anywhere. I don't know if you need to see any of my config files but I can post them if needed.

I setup a postfix mail server. Tested it to make sure it was secure and all seemed good.I sent some test messages and see from the logs that mail is being delivered to the recipient. its only delivering mail to my user's local mbox on the linux server. IMAP appears to have its own mailbox and the two boxes are no linked. I was thinking it was an alias issue however I did at one point have the mailboxes to be the same.... now they are different... Here is the config file.... (I changed the domain names for privacy).
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix

I'm configuring a server but at this time I can't send mail. I tried using the PHP mail() function and it didn't work. Webmin says I have no mail configured. I'll be the only user and mail recipient. I've used Squirrelmail and Roundcube before and liked them.
Do I need to install Postfix in order to user Squirrelmail or Roundcube? How should I set up mail?
Here's my setup:
10.04 LTS Server edition
Webmin 1.520
Apache 2.x
MySQL 5.x
PHP 5.x

(We are running CyrusIMAP v2.3.16 on Slackware 13.1)The Problem:A user deleted a HUGE public Folder (>10000 Messages, >250 Subfolders), and now the Folder is in his "Trash" folder.Besides the obvious "Why did he have the access rights to do so in the first place??" question, I am honestly at a loss as to how the user did it:Trying to copy it back using Thunderbird failed utterly, TB crashes, or copies only a part, or nothing at all... (Tried 3.x on Windows and Linux Clients)So now I'm searching for a way to copy the folder back serverside.But web and manpages seem to offer few help:I don't want to move the folder to another partition, nor do I want to reconstruct or restore any corrupted data...All I want is to copy the folder from "user/USERNAME/Trash/HERE" back to "shared/archive/HERE".

I was trying to have access from a browser to the squirrelmail configtest page in my server, making some changes, I accidentaly remove the directory webmail. After I replace it with a backup apache2 can not start. This is what I have. Syntax error on line 281 of /etc/apache2/apache2.conf: Syntax error on line 1 of [URL].. closed. But I am sure there is a ?> at the end of this file.Base on what I read on [URL]...-with-the-tag/ I test without the ?> also, but I got the same error.

Does anyone know if there are only personal preferences between the two IMAP servers or does one of a slight advantage over the other? I've used Dovecot only in the past but my package manager loads tons of MySQL libraries with Dovecot which is a problem since that's not authorized on my server right now. I can either install it from source or try another application like Courier.

Im looking for a way to block emails that come into the mail server for users that are no longer on the domain. I see a lot of messages in the maillog for emails coming in for people that are no longer active users on the domain.
setup:
Using spamassassin if that matters.
Using Active Directory on a windows server.
I found postfix uses this "reject_unknown_recipient_domain" in /etc/postfix/main.cf but I am unsure where this would be used in courier.
Ive seen some hints here. But not sure how to adapt this for domain users.

how to install Courier IMAP server and they all say the same thing, but they keep giving me problems.URL... is a link to the page I'm working on.I created the user, edited sudoers manually since I can't effectivly use visudo in the terminal since I don't know how to save. I also made sure that I restarted after I edited it in order to make sure it took effect. I used su compileuser and just logging in as compileuser and opening a terminal. After I made the user and edited that file, I created the directory mentioned and ran the command to create .rpmmacros. After that I got to work on wgetting the files and installing them and what not. The first one compiled and installed and so did the last one. The command "rpmbuild -ta courier-imap4.6.0.tar bz2" would not go though properly. This one I need to run as a non-root user and I've tried using every way possible to be as distant from root as possible, but it still gives me this at the end.

Using the following software:
Ubuntu Server 8.04
SquirrelMail 1.4.13
Postfix 2.5.1
Courier 0.59.0 (Courier-IMAP 4.3.1)
Apache2 2.2.8
I've installed a mail server per the instructions at [url].
Neither POP nor IMAP test successfully with the user that I just added after following the setup instructions.
This doesn't make any sense. I added the user to the mysql database:
Code:
And after I did that, I ran the postfix reload command. If I try to log in as firstuser@mydomain.com, which is the user I created during the setup and configuration process, it works fine.
I checked the virtual mail account's home folder, and under the mydomain.com folder, I only see a folder for firstuser. I'd create one for testuser manually, but I don't know if that'll work since it seems to contain a particular folder structure of its own.
Is there some other command that I have to run? I don't recall having to do anything additional when setting up firstuser.

I have had a mailserver die when it still had email that the users hadn't downloaded. I have build a new server an tried to copy the mail across but this caused a issue where users were unable to download any new email.
Is it possible to make the old undelivered email available for download?
old server name lx0.hostname.com (dead) I can get to the data but not start the server. new server name lx1.hostname.com
Both systems were running qmail with courier.
