Red Hat :: Email To Mailman List Got Rejected By Postfix
Jan 22, 2011
mailman configured with postfix & dovecot on the same server. Postfix & dovecot configured using iredmail script. This situation is possibly caused by dovecot LDA but I do not know how to configure it to recognize mailman lists I'm using RHEL 5.5
Here's my configs:
/etc/postfix/main.cf
Code:
alias_database = hash:/etc/postfix/aliases
alias_maps = hash:/etc/postfix/aliases, hash:/etc/mailman/aliases
allow_min_user = no
biff = no

I've got a general question : I am using F13 for servers... I planned to use a mailing list now.
1) Which one would you recommend ? Mailman or Majordomo ?
2) I am looking for the possibility to get feedback of the mailing list.. ( Who opened, how many times..etc... )
Does Mailman provide this kind of info? (I didn't find anything on this during my first research). If not, which additional software can do it?

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?

Im pretty sure this is trivial to config, but I havent had any luck searching on google.My situation is: I want to forward any emails sent to my domain to another account. So:
Code:
root@domain -> another_acc
any_other_system_user@domain -> another_acc
any_unknown_user@domain -> another_acc

Currently i'm figuring out how to send email notifications to users when services went down in Nagios. I know i need to install and configure Postfix, which i did already. I assume that when i configured to point it to "Satellite mail system" is the correct one instead of other things like "Internet.." etc. So the configurations is when you have installed the Postfix and there would pop a lot of questions right? Other than that, what have i missed?
Oh ya, i remember something. Hmm. I do not have any so-called real smtp server so would that be alright? I heard that installed and getting the Postfix running would be enough as it serves as a MTA (mail transfer agent). So if i do not have any smtp server, the relay host= ' ' what should i put it as?

I am trying to setup a simple SMTP server to relay scanned documents from a Xerox machine to email addresses. Unfortunately the Xerox machine doesn't support TSL or SSL so sending mail over port 25 on gets blocked. I have setup postfix on a desktop running Fedora 13 and have been able to set it up to forward the mail onto the correct server (gmail for example). My question is, how do I get the server to encrypt the emails (scanned documents) when sending them over the internet?
I have tried adding:
Code:
smtpd_use_tls = yes
smtpd_tls_cert_file = /etc/postfix/smtpd.cert
smtpd_tls_key_file = /etc/postfix/smtpd.key
But when I look at the wireshark capture of the sending I can read my test message in plain text.

I have a server with an sms-terminal attached. There I use "gnokii" to send sms. Now I'm searching for a solution with postfix or something else to receive an email and resend the subject of this email as an sms with gnokii. I have already searched a lot. I found that I have to create a special "sms"-user and a .procmail / .forward-file. But I had no success with this solutions.

tell postfix to send email sent to one email address to another email address. What I really need to do is tell postfix that every email sent to [URL] and [URL] be sent to [URL] I tried transport maps like this: [URL] but that did not work. I then tried canonical maps like this:
recipient_canonical file:
/^((dbsupport|helpdesk).*)thisdomain[.]com$/ admins@thatdomain.com
sender_canonical file:
/^(.*@).*thisdomain[.]com$/ ${1}thatdomain.com
but it did not work either. I am really exhausted and I need to find a solution for this one since it is my boss asking me to get this working. This is what if in /var/log/mail in box1:
Dec 28 16:10:25 box1 postfix/pickup[19291]: 54D258F726: uid=0 from=<root>
Dec 28 16:10:25 box1 postfix/cleanup[23489]: 54D258F726: message-id=<4D1A5241.mailIBZ11LRR6@box1.thisdomain.com>

I have an issue where postfix is setup to use dovecot auth and as far as I know it works, if i login using telnet to the mail server i can authorize myself y providing the base64 encoded user & password. so if i can login, why cant my email clients. have tried thunderbird and evolution. this is the mail.log relavant entries for sucessful login via telnet
[Code]...
Login by pop or imap works flawlessly that what i dont get. From what i see it SHOULD be working. It it changes things, im using postfixadmin, postfix, dovecot. passwords and info stored in mysql tables. passwords are md5 encrypted. I thought that may be the issue, but that dosnt make sence.

For legal reasons, I may soon be required to have the ability to provide a user's emails to authorities as part of a discovery action.Not just a copy of backup.I'm running postfix with dovecot on rhel5.I'd need to be able to produce emails sent and received in a given time frame by a given user.

I have postfix sort of working correctly. postfix can send email to the internet but it doesn't want to send email to my local exchange server. What I need is for postfix to send emails directed to @xyz.com to my exchange server instead of itself.
My setup
mail.xyz.com - exchange 2003 server
www.xyz.com - centos 5.3 server with postfix
www.xyz.com can send emails to my hotmail.com account so that part works correctly. www.xyz.com can't send email to username@xyz.com. postfix seems to be delivering the email to itself and not the exchange server.
How can I tell postfix to send the @xyz.com emails to my exchange server?
Here is a sample of my /var/log/maillog
Jul 22 15:43:43 list postfix/smtpd[9802]: D63168604A3: client=localhost.localdomain[127.0.0.1]
Jul 22 15:43:53 list postfix/cleanup[9805]: D63168604A3: message-id=<20090722204343.D63168604A3@www.xyz.com>

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'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 want a mail server that can work just like MDaemon. The reason is, I want to have an email content filter rule that does some thing like this.
1. If the To Header contains "support@thisdomain" then run a program.
What this means is that, there is a program here in the office, and if some one sends an email to the support address, with an attachment of .exe and that person is a customer, then the program should be run. The only thing I need here is if there is a rule or script that can filter email header and run a program.
2. If the Exit Code from a previous 'Run program' rule is in the range of 1 to 100 and if the To Header contains "support@thisdomain" then send note1 "to<email address>" from <$SENDER$" "SUBJECT <AM ...>
and delete this message.
3. If the EXIT CODE from a previous 'Run program' rule is =0 and if the TO HEADER contains "support@thisdomain" then send note1 "to<email address>" from <$SENDER$" "SUBJECT <AM ...>
and delete this message.

I have an ubuntu server running postfix 2.6.5 (configured using DTC). If a user tries to send an email to more than one recipient, and one recipient address is bad, then the server returns an error and no mail is sent (even to the good addresses), rather than letting the good ones through. Error displayed by thunderbird is
Code:
"An error occurred while sending mail. The mail server responded: 5.1.1 [URL]: Recipient address rejected: User unknown in virtual mailbox table. Please check the message recipient noreply@domain.com.au and try again." and mail.log shows ...

I have a postfix system that sends allot of emails to customers and web site visitors. A lot of visitors just enter an invalid email in the WEB form just to download some files or do other tasks. Is it possible to BLACKLIST specific email addresses so the system does not send to those addresses? I can grep from the postfix mail log all those fake emails and place them somewhere.

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.
