Ubuntu Servers :: Installed Postfix Setup - Can't Access Email
Nov 20, 2010
I installed Postfix, Amavis-new + Spamassassin + Clamav, Dovecot, and SquirrelMail today, using the Ubuntu guides for each. I have 10.04 LTS Server. My PHP scripts can send email, but when I tried to log into Squirrelmail, I couldn't. Here is what my error log produced (the server name and user name have been changed) :
Code:
myserver dovecot: imap-login: Login: user=<username>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured
myserver dovecot: IMAP(username): opendir(/home/username/Maildir) failed: Permission

I'm trying to setup postfix (or exim, I don't mind which), so I can move away my last remaining PC from Windows.I've tinkered with Postfix for good part of a month and I can get it to accept emails using SMTP and post them to a virtual mailbox based on MySQL tables. And it rejects mail addressed to local email addresses that it can't find in the table.
First question (or problem.) I've set up Postfix to relay email it cannot deliver locally such as is the case when you send out an email. My remote host requires authentication. How can I set this up?
Second question: I want to force my clients to use either AUTH, TLS or SSL, and not allow anonymous connections (to prevent an open relay server.) How do I set that up without interfering with the smarthost setting? The smarthost login is not one of my clients, it's a pre-determined login and password that is solely used for the email relaying aspect.

I have an email setup where all of the emails from our email host is downloaded to our Linux server using Fetchmail. Then some of the incoming emails are sent to an MS exchange server (server1.domain.com) using Postfix. What i want to do is to send a copy of all emails to Another server (server2.domain.com) for redundancy.Can postfix be configured to send copies out to both?

It wasn't too long ago that I discovered Linux/Ubuntu (in terms of actually USING it) and I've been completely blown away by the capabilities it puts in the user's hands! To think that someone can take an old desktop from a trash pile (literally, in my case) and turn it into a web server for ZERO dollars is absolutely crazy.
Anyway, I've been using said desktop as a sort of "dummy" machine to learn Linux. I want to be clear that I've got another computer for personal use and that I understand that setting up server software on any computer poses a security risk. Having said that, I have a few questions regarding mail servers and their setup on Ubuntu. Again - I'm comfortable with what I've done so far in Ubuntu (installing packages, terminal interaction, basic usage)
My question is mainly this: if you have, say, a domain name through DynDNS (let's say example123.com) and it points to an Ubuntu system, does something like Postfix enable you to make your own email addresses such as user1@example123.com and have an email server from wherever the Ubuntu system is?
I've been following the basic Postfix setup here and have had success so far (down to the "Adding your local domains to postfix" section) bu wanted to make sure that what I'm intending to do is what I'm doing (haha... i hope that makes sense). That is: get domain name at DynDNS, host pages on LAMPP server, use Postfix to facilitate incoming/outgoing email for that domain name.

I'm running ubuntu 10.04 as a server that hosts a website and our email. I set up the email (Postfix) to work with Dovecot to enable IMAP and POP support.The mails can be retrieved and sent through this server with no hassles. We just have an issue that all emails sent via a client to any other address (be it on the same domain or not) will return to the inbox of that client.So basically, I open MS Outlook. Click new message and send it off to my GMail address. After I send it, it pops into my inbox on Outlook (stating that it came from me). The intended recipient also gets the message.

I recently Re-did my Postfix configuration using [URL] The thing that that guide did not tell me was how to get email to forward to other accounts or if I can point multiple accounts to the same place like here:
[Code]...
finally I tried putting a .forward record in /home/vmail/domain.com/username directory which didn't work either.

I have a very basic install of dovecot and postfix on the latest version of Ubuntu server. This is an internal only email server with internal only DNS. I can send email via clients and check said emails via the command line when logged in as the appropriate user. I cannot for the life of me check said emails via SquirrelMail on the server nor using IMAP clients. I have no idea where to look and I can't find a basic tutorial for the life of me. Where should I start?

I have been running an email server on a Red Hat 9 system for 5 years, and wanting to upgrade it to the latest Fedora OS. A few days ago it crashed. The server is running Fedora 11 (up-to-date). Clients are Fedora 11 and Windows XP machines using Thunderbird for accessing email. The server is running Postfix and Dovecot. Within my local network I can send and receive emails. I can also send email to addresses outside of my local network. The only problem is that I cannot receive any email from outside the local network. I cannot think of anything aside from my firewall (iptables) or postfix config that could be causing the problem.
Below are my iptables file, and the postfix main.cf changes that I have made.
Iptables (the same file I was using on Red Hat version 9 with one minor deprecated syntax changed):
*nat
:PREROUTING ACCEPT [22:1894]
:POSTROUTING ACCEPT [14:840]
:OUTPUT ACCEPT [17:1356]
-A POSTROUTING -o eth0 -j MASQUERADE
COMMIT
*filter .....

I have an email server configured with postfix, dovecot, saslauthd and squirrelmail. It works great. In fact I'd even say it works too well: in squirrelmail, I can configure any sender address and my server will accept it. Message will be sent, wether the sender's address is [URL] or [URL]. Is there any way of limiting it in such way that only [URL] is accepted as sender's address?

I'm testing my mail server, and sending email works fine. However, when I tried to send emails to my server from gmail, I get this log:
Code:
Aug 8 14:18:17 anbient postfix/smtpd[14228]: warning: database /etc/postfix/virtual.db is older than source file /etc/postfix/virtual

And this is strange. 174.132.240.146 seems to be the web address 'net.net'. I am sure this has to be some setting in postfix, cuz its trying to deliver the email to 'fidelix@net', and that cant be right.
Here is my postconf -n output:
Code:
root@anbient:/var/mail# postconf -n
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no

After a reboot of my VPS, I keep getting the following error when sending email to my domain (hosted on Google Email). I can send to other email addresses but my own. So it seems like postfix thinks all mydomain.co.nz is to be sent internally?
Sep 9 09:25:05 mydomain postfix/pickup[20784]: 0316C3CC68: uid=1000 from=<sidb>
Sep 9 09:25:05 mydomain postfix/cleanup[20806]: 0316C3CC68: message-id=<20100908212505.0316C3CC68@mydomain.co.nz>
Sep 9 09:25:05 mydomain postfix/qmgr[20783]: 0316C3CC68: from=<sidb@mydomain.co.nz>, size=326, nrcpt=1 (queue active)[code].....
How do I tell postfix that mydomain.co.nz is to be sent to Google email server?

I am trying to configure virtual alias using regular expression.
For example :
Email send to user.1@example.com and user.2@example.com will deliver to user mailbox.
Email send to user2.1@example.com and user2.2@example.com will deliver to user2 mailbox.
And the numbers or alphabet in between user name and the domain will be vary , I can't just do a normal alias.
I been try to play around with main.cf and the virtual alias table but still not able to get work. So I am not sure is the main.cf didnt configure correctly or the regular expression is not working.

I have a problem setting up Postfix on my home (behind Router/firewall) Ubuntu driven server, I have been trying for days now with no luck. All I would like to do is use the server to send mail (MTA). So while installing I configured it as a satellite system.
file:
/etc/postfix/main.cf
settings:
myhostname = mail.example.com
mydomain = example.com
alias_maps = hash:/etc/aliases
[code]....
I'm getting a 553 From address not verified. I have tried what it suggested from the URL link, but it still doesn't work.

I recently setup a server running subversion. It is working well and all, but I am curious as to how to make it send out email alerts to my team when a commit occurs.Also, are their any good GUI tools to manage a subversion server in Ubuntu. The command line is fine since I made some scripts but a nice GUI would be great! Maybe that could be a fun project to work on.

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 configured my server to have the virtual mail authenticated and stored through mysql DB.Now the authentication works, but then I got the dreaded -ERR chdir error.After research and testing for ohurs I finally got it working on ONE account after I created the maildir with maildirmake.Now I am able to login and "list" messages, but nothing else. When I use postfixadmin to setup a new user, the maildir does not get created so I have the same problem.I'm trying to troubleshoot what is happening.Here are the relevant config files:
/etc/postfix/main.cf
Code:
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no[code].....

I'm trying to figure out how to access the local part and the domain part of an email address in postfix's main.cf. For example, myname@mydomain.net has myname as the local part and mydomain.net as the domain part.I get the whole email address with %s. I want to speed up the lookups by writing better database queries.I've had no luck finding this in the otherwise well documented postfix.

I'm having problems with emails containing HTML content. When Google downloads the email messages via POP3 from my squirrelmail server, the message does not display using HTML. I'm not sure if this is Google's fault or Squirrelmail's fault, but I've never had problems before on other servers running the same script and using squirrelmail. If I login to squirrelmail, I have the option to download the email message as an attachment. The attachment, if opened by my local browser, shows up as HTML content, and it is properly formatted. However, I'm using Google to download my emails and file them under my Gmail account. After Gmail downloads the messages, it shows up like this:
From
To admin@domainRemoved.com
Date Sat, Jul 30, 2011 at 6:07 PM
Subject Pending Registration
Content-type: text/html; charset=iso-8859-1
From: Name Removed <admin@domainRemoved.com>
Message-Id: <20110730234302.6B6FEDC08BA@eric-desktop>
Date: Sat, 30 Jul 2011 17:43:02 -0600 (MDT)
<p><b> After registering your client via your server, please visit the following URL to send them confirmation: </b></p>
I really need it to show up properly once Gmail downloads the messages, as it takes a long time to login to Squirrel mail and download each message as an attachment. My PHP Code Headers Look like this:
$headers = 'MIME-Version: 1.0' . " ";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . " ";
$headers .= "From: $uname <$email>";
Someone suggested that I remove the from my script. I did, and now the email shows a from sender as www-data www-data@domain.com. Before, the from field showed up as empty. However, my PHP script is designed to change the sender's information to the clients that contact me. Thus, if customer A contacts me, the email should be from customer A <custa@whatever.com>. However, it's not being changed by the PHP script. It works on every other server but mine. I think my postfix configuration isn't setup properly? What needs to be configured on it?

I am very new to Ubuntu (any Linux) evironment. And it has been a long long time since I have dealt with seting up servers. I have done alot of searching but haven't found exactly what I THINK I am looking for.
I want to create a file server (I have created my Ubuntu server cd) and add it to my home network (all windows pcs). I need to be able to access it when away from home ( I work away from home mostly). I will be accessing this with a Windows 7 laptop.
What do I need installed on the server? Samba for the file server part. What else for the remote access? I also would rather not access the data via FTP. I would like it to come up as a drive in my Windows Explorer. If not, I remember back in college (20 years ago) when I could open a little window (XWindow maybe) on the other server.
An issue I see that might not be an issue. I have a static IP from my ISP. It comes into my home via their modem. I attach to the modem with a router. All my laptops connect to it wireless and this server will be wired. How do I hit the server and not one of the laptops with only having the one IP address? Each of these plus my external harddrive and printer have their own internal IP address' that I have assigned.
