Server :: Basic Postfix And Dovecot Mail Server For A Test Environment?
Sep 16, 2009
I did a a basic install of postfix and dovecot instead of using courier-pop and courier-imap. This is only send and receiving e-mail locally within the test network 10.7.0.X and 10.0.0.X. I used:
[URL]
my postfix.conf is;
PHP Code:
[code]....
This is the error when I send an email from a local machine on the 10.0.0.X network.
PHP Code:
Jan 20 17:05:48 testbox postfix/smtpd[2491]: warning: Illegal address syntax from unknown[10.0.0.111] in MAIL command: <test@10.0.0.112>

I am running Fedora 10, Postfix and Dovecot I recently changed the password of a user using the 'passwd' command. The problem is that the user can no longer receive their email messages in Thunderbird (Authentication Error). However, they can still login using SquirrelMail and get their mail.

I'm somewhat familiar with Linux and became pretty decent at installing and configuring packages in Ubuntu. One of the things I was able to do with my tinkering was set up a functioning imap and pop3 mail server using dovecot-postfix. Now I'm experimenting with Slackware to get the feel of another distro, and I noticed that the mail server packages were already installed. On my client computer they can pick up that I have users configured and my mx record is working.
However it is failing to send mail saying that it is failing to relay the e-mail message and that the server responded 5.7.1 which was a problem that I was having in Ubuntu when first configuring the mail server. The fix was to edit the postfix.conf file and adding the localhost name of my server. Does anybody know of the file that I need to edit to make it possible to relay my messages with both pop3 and imap.

I've setup my server by following a ton of goods, and it seems to work ok, but I need to start using my server for email in order to receive orders placed via my website. I've followed this guide - [URL] I followed the steps above, and tested the mail server via telnet, and all seemed to be ok. I tried sending an email via Squirrelmail, from cs@thinclientwarehouse.co.uk TO my working email simon@c1systems.co.uk, but the server returned with the following message:
<simon@c1systems.co.uk>: host mail.c1systems.co.uk[95.128.128.129] said: 550-Verification failed for <cs@localhost.thinclientwarehouse.co.uk> 550-The mail server could not deliver mail to cs@localhost.thinclientwarehouse.co.uk. The account or domain may not exist, they may be blacklisted, or missing the proper dns entries. 550 Sender verify failed (in reply to RCPT TO command)

Im a fairly new linux person and have a hopefully easy question. I am running centos with dovecot and postfix for the mail. Im using imap so all the mail is on the server. Im also using thawte certificates. What is the easiest way to move all of this over to a more stable box? The box i have now is a major POS.

CentOS 5 box was just setup to replace a crashed old one. I have postfix.admin installed and working, added users (confirmed from mysql command line) and can login using telnet server pop3 with the user information. The problem I am left with is just receiving mail. I have both squirrelmail and roundcube installed, and can also authenticate using both (/var/log/maillog shows);From either webclient I can naturally send mail out and both yahoo and gmail client confirms, yet a reply shows nothing, and nothing ever shows in the maillog. Firewall is shut down but I don't know postfix enough to see how to test, or is something else grabbing the mail.
I can provide anything necessary, just let me know what. As I see it (just so far) Postfix should be the server that answers and receives the mail, dovecot is more the pop/imap the client would use, so I think it's a postfix issue. If so, can I turn up the debugging, etc. but again, I think all mail received should appear in the maillog file 1st as I see the outbound mail go fine!

I am running CentOS 5.2 on a server here in my home. It runs Dovecot and Postfix and also serves as a website host for a small website of mine. Everything works fine. POP, SMTP, Webmail, WWW, all works great and has for ages.Here's the issue. I recently reinstalled a clean copy of Windows 7 on a workstation in my home onto a new harddrive(I still have the old drive int he machine so I can boot to it as well). I setup the Windows Live Mail client to send/receive mail with my mail/web server. However, it won't connect to the POP server on my server machine.Here's the kicker. If I boot to the old harddrive that is running Windows 7, it connects fine to my mailserver and can send/receive just fine. I've checked, rechecked and rechecked and all mail settings on the mail clients on both drives are identical.
Note: The installations of Windows 7 on both drives is identical. Same computer name/ same credentials, same IP, etc. However, as I stated, I can send/receive email with my server if I boot to my old drive, but if I boot to my new drive, I cannot send/receive.

I'm sooo exausted after two days of fooling with this. The problem: Apr 27 17:29:21 mxkasib dovecot: lda: Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: Permission denied (euid=8(mail) egid=12(mail) missing +w perm: /var/run/dovecot/auth-userdb, euid is not dir owner)
Obviously, dovecot-lda, instanced by postfix, couldn't access the auth-userdb file because of permission. There are plenty of topics over the internet, the problem is really simple. Except for I've got all the permissions needed, or it seems to me so and I'm missing something. Here is some additional information:

I've given all the permissions I could imagine. It's even devil 666, and it still complains.

We are planning on rolling out a mail service that will backend a webmail/groupware interface using postfix and dovecot, and we are trying to nail down an architecture for the system. I was hoping I could get some opinions from you good people on the different models we have come up with, and any improvements. To preface this discussion, we use NFS as the backend storage for mail so that clusters of mail servers can be created.
One possible solution is to separate three services, inbound email, outbound email, and message retrieval onto separate servers. We currently run a mail system with 65K users in this manner and it works, but there is a lot of wasted cpu on the inbound and outbound mail servers. where the dovecot servers are doing most of the work.
Another solution would be to combine the dovecot and inbound postfix servers to run dovecot as the local transport agent for postfix with LMTP, giving us quota and sieve capability.
The last solution is to run all three services on the same machine, giving us a single server image that we can clone on demand when we need to add more performance.
The single server, all three services, solution seems to be the simplest to build and manage, but putting all your eggs in one basket like that concerns us. What if there is a sudden influx of mail from our filtering platform, and it slows down all the other processes? What if the NFS server becomes disconnected from the network and the load average on each server skyrockets killing the ability for outbound mail to flow (where a separate outbound mail server would continue running despite this issue)?

I have a Postfix+Dovecot and virtual users setup taken from here. I've got virtual users authenticating using a password file. But I'd like to lock the service down further, so authenticated users can only email other authenticated users (those listed in the same password file) - so it's a closed community. I don't seem to be able to stop authenticated users mailing outside the community.

Is there any application (preferrably web) that can monitor in real time what is going on in my mail server?
Who is sending to who
Who is receiving
List of incoming/sent mail
Dovecot mailbox size
Monitor postfix queue
etc.

I am running the following on CentOS 5.5 (Final)
dovecot 1.0.7
saslauthd 2.1.22
When I send an email via TLS I see the following log entries.
Code:
Oct 14 11:53:06 ns2 postfix/smtpd[11372]: connect from unknown[172.16.1.159]
Oct 14 11:53:06 ns2 postfix/smtpd[11372]: setting up TLS connection from unknown[172.16.1.159]
[Code]....
What I'm really curious about is there is an intial TLS connection with a 256 bit cipher, but then.. The last entry states "sasl_method=PLAIN" - so surely this is not encrypted? Or am I misunderstanding how it works?

I followed the Wiki guide for configuring my Postfix server for SASL / TLS. I don't get any errors and I assume it's working but when I try and test SASL (saslauthd), I don't get the response noted according to the Wiki and I don't understand why.

I have a problem concerning the vacation(auto response). I got a mailserver(smtp.mydomain.com), pop3/imap-server(mail.mydomain.com) webserver(www.mydomain.com, with postfixadmin on it). I use Debian 5.0 So it's like this, I receive mail to smtp.mydomain.com, it get checked for spam with amavisd-maia(Maia Mailguard), then delivered to the pop3/imap-server. I'm guessing there's something wrong with my postfix setup. I activate auto response for my account, when I get a mail it says this at smtp.mydomain.com:

so i set out to change the default smtp port the server uses because my ISP blocks port 25 and i need the email to work in outlook. this morning i could receive email, but not send it. so i did some research and thought that i needed to edit the master.cf file in /etc/postfix/ by commenting out this line: smtp inet n - n - - smtpd -oand replace it with587 inet n - n - - smtpd (587 being the port i want to use)somewhere along the lines postfix server stopped running and now i cannot get it to start.if i try using SSH it crashes immediately and if i restart it in simple control panel nothing happens

I do not know why I could send email outside but not receive. I use relay to my ISP that port 25 is blocked by my ISP. What can I doing with configuration when it should be works to receive mail? Okay, I have sent a test e-mail between localhost and it works. I can send from mailserver to my gmail without problem. So why I cannot receive email from gmail?

For use on a test LAN, ie. security is not an issue, I need to install the most basic FTP server available just so we can share files back and forth between test hosts : launch FTPd, have it share a directory through either "anonymous" or a single, shared login/password?

Two exchange servers internally. One is setup for example.com (192.168.1.10) and the other is setup for example2.com (192.168.1.20) Both are behind a single public IP.
I want to use postfix to sit in front of the two exchange servers. Postfix will accept mail for both domains and relay to the appropriate server. I have postfix installed with only defaults at this point.
