Server :: Users Received A Spam E-mail Without Subject Line
Sep 19, 2010
I need help with header_check filter on postfix. In the last week mail users received a spam e-mail without subject line and I don't know what is the way to reject this. This is the example of message header:
From: "example@example.com"
Date: September 16, 2010 9:07:43 AM GMT-04:00
To: <example@example.com>
I want to reject e-mails that don't have Subject line
After installing postfix on my server , all emails sent by a PHP class that i built , are received to spam folder , no matter what i do .am not an expert , except in PHP , the class i built works fine everywhere else except on this server , so i think the problem might be from the server it self ?some told me wrong configuration/software on my server , others told me wrong DNS stuff . actually i don't understand the DNS stuff , and am not an expert in linux softwares and services but i cann install/configure them , so could anyone please check the DNS for problems ?
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: From userNAme Sat May 22 01:52:27 2010 X-Apparently-To: me@yahoo.ca via 98.136.183.25; Fri, 21 May 2010 14:52:55 -0700
Did anyone heard about or can suggest mabe a postfix serverside solution in order to insert a counter number into the subject line before the message is sent? I mean something similar with helpdesk tickets, because I would like to create the possibility for the senders, to make further refference about a speciffic message using it's counter number provided by postfix server.
I am using postfix as spam Mailscanner to protect my mail server running sendmail. The problem is that when I forward an email from MailScanner mail me back with the following error:
<postmaster@localhost.@mydomain.com.>... Real domain name required for sender address (in reply to MAIL FROM command)) Jul 27 13:15:59 smtp postfix/local[28465]: C68AC1000001: to=<root@smtp.mydomain.com>,
The mail server is not on my local LAN, and all the primary users are roaming. They connect via TLS auth, which is required to make a sendmail connection to my server. I could whitelist all addresses in my domain, but then anyone spoofing my email wouldn't be seen as spam. How do I simply tell amavis-new and/or sendmail not to spam scan TLS authenticated users?
After reading everything that says you don't need an anti-virus for Linux. OR Linux doesn't get viruses. Guess what I have a Virus. I don't know which one, but it is sending out spam emails from my webmail, MSN, account. I do not have a local client installed. I am guessing it is linking into MSN through Pidgin, getting the addresses there, and sending the spam, somehow, through MSN. Actually one MSN and one Hotmail account. I also have not been able to find an anti-virus program for Ubuntu. There do not seem to be any listed in the software repositories that Ubuntu links into. How do I get rid of it? My contacts are starting to get upset.
I was wondering if there was some kind of anti-spam proxy available for debian, that could serve as a layer between my ISP's mailserver and my email client. Something light, as it needs to be installed to a guruplug server with not much storage available. It would be great if I don't need to configure a fully fledged mail server but if it can function on it's own, only filtering spam messages. I already found assp and qpsmtp, but I find these very difficult to setup and assp is like huge.
I am new comer in this forum and the beginner on freeBsdI have a problem on how to implement the spam filter program on mail server, the problem is i have no idea on how to implement and test the spam filter program on the mail server and where should i put the program? is it in pop3?
I'm new here and I'm sure this question has been thrown around a lot but I just couldn't find a solution. I have a networking website I've setup and we need to send notification mails to our members depending on activity related to their profiles(messages, comments etc).We are hosting the site on Centos5.6 with VirtualMin and are using Postfix as our MTA. We also use google apps for email on the site. Heres the problem, the mails go through for some gmail users but more often than not, they end up in gmail,hotmail and yahoo spam.We've setup the appropriate SPF codes on the server, DKIM and rDNS works fine.v=spf1 ip4:xx.xx.xx.xx a mx include:_spf.google.com ~all Below is a sample email that goes directly into gmail spam. I've replaced the actual values with dummy text (Ip, Domain etc)

I am using Postfix on CentOS to send mail through a relayhost. The mail sends fine, but on certain clients such as the mail client on the iPhone or Windows Live Mail, the message is received with '(No Sender)' in the sender field. The Apple Mail client on the iMac works just fine.
Here is the PHP code I am using to send the mail code...
Wondering if there is a configuration setting in /etc/postfix/main.cf I can use to fix this problem. I have scoured the help files but have come up empty.
How can I split my local mail box into an individual files for each mail. The senario of mine is I fetch some emails from a mail server into my local linux box with fetchmail command but I want each fetched mail in a different indivitual file for easy file processing and manipulation for example sending those email through sms and so on
I'm running SUSE linux Server version 11. I want to configure mail server with postfix & cyrus-imap. For that, i have read many documents in Internet by i met issues. I'm running DNS in this server & it's ok Now I cannont send mail through command line.
Request your help in writing a shell script for the following requirement:
1) scan each incoming mail with conditions on sender name and subject 2) scan the mail body for set of characters and email them.
general usage is as follows: I get a mail as follows from: [URL]... subject : Urgent, reply body : name : xyz contact : 12345 the script should mail the following as subject line: n:xyz c:12345 I know procmail is a good option for this, but I'm compelled to use shell script
I dug up an old P2 machine and loaded it with 320MB of RAM and a cheap BIOS-less RAID card using a VT6421 chipset. I attached a 1TB SATA HDD to it and booted it up with the latest gentoo minimal install disk. I have installed gentoo before. The first problem I had is that the system would hang at Scanning for sata_via.... I resolved this by booting with "nosata." This brings me to my first question: Will I be able to use my drive once the OS is installed? It seems like the answer would be yes, but I wanted to make sure.
After booting with the 'nosata' option the system would hang at scanning for pata_qdi.... I resolved this by booting with 'noload=pata_qdi.' Now the system is hanging at: attempting to mount media:- /dev/hdc I have been searching but have not found anything definate on this one. One post ( i am sorry but i forget where; i was working on this for hours) suggested that the problem is caused by the age and speed of the drive. I really don't know much about these things. Can anyone confirm this? Is there a way to make it work, or do I have to replace the drive? If I replaced the drive won't the new one just slow down to accomodate the old motherboard?
I just setup SpamAssassin and what not following this tutorial

I am using CentOS 5.3. I was half way through that and got an email that had ***SPAM*** in the subject. Haven't received any more. First of all I want to know if spam will still get delivered, and just have a modified subject. Second, I want to know how to set it up so Spam goes to a user's spam mailbox (Virtual Users). And third of all, is it possible to disable spam filtering on a user basis, preferably using MySQL tables? Is it possible for users to mark a message as spam, and all further messages sent from that address will be sent to spam folder but only for that user?
EDIT: Yes spam is getting delivered with a modified header, on the server site, how can i deliver to spam folder? how to create IMAP virtual mailboxes on request without having to send an email to them first? Using virtual users with Courier Imap
how to set up a simple rule on the server side so emails with a certain subject just go into that user's .Trash. Right now my users will get roughly 25,000 of the same email from our corporate offices and it is destroying their email clients. I believe the mail setup is postfix and courier with virtual users. I tried googling this up but I couldn't find much current or ubuntu-specific information.
I currently have the following email server set up:
Postfix with mysql backend Dovecot clamav spamassassin amavisd
And it all works great. However I would like it for amavisd to forward all the marked spam into a folder on each user account, but I cannot figure this out.
I would like to set disclaimer like content in my meral mail server, so that all the users should be able to get that content automatically in their outgoing mails.
how to defend from spam mail, actually i used centos. i want to absolutely block spam, my Mailscanner running ok but the spam still run off to my server. i do everything from tuning mailscnnner, spamassassin, amaisd-new but spam still send to user 10-20 per days.
I am using Centos 5.4. sending e-mails through our network(LAN).i want to create a e mail address's for each user and wants to give facility to sending,viewing,replying & forwarding office e-mails
I had setup postfix and spam assassin, and in my environment, I forward the incoming email to my exchange server.
Everything works now, in my mail box, I can receive the email with subject ******SPAM*****. but is there a solution, when spam assassin finished the scan and mark spam, if the score is very high, may be stop to forward it to exchange, for example, send it to a special email box?
I've got a web server that's hosting a few sites, and there are a few WordPress instances with these sites. With Wordpress, whenever a user registers with the site, they receive an email.With my server, it sends mail via Sendmail. This is all fine and good, except no matter what, it's flagged as spam. Is there any way to correct this?Keep in mind that this isn't a mail server, and the only reason the server ever sends mail is for new wordpress users and password resets.
Does anyone know if it is possible to set up Postfix to receive all email coming to mydomain.com and forward them to 2 different spam filters? All mail needs to go to both spam filters then onto our Exchange server
I am receving emails from logwatch but when I setup my own mail script using mutt, the script succeeds but no email is received.Any ideas what the difference is between the two mail methods?
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 installed sendmail in RHEL5.4 with TrendMicro Spam scan engine. The configuration like sendmail should forward all the mails to scan engine after scanning it will deliver it to the mail domains. same way all the mails coming from external servers are scanned and the delivered to local box. My problem is when i sent mail for local users its delivered locally. but when i sending mail for external like yahoo its going through scan engine. I added the smarthost in sendmail.mc file also.
I installed and configured postfix per the guide on help.ubuntu.com. Everything seems to work fine with smtp and it says that my emails are being sent, but I never receive them.What could be causing this problem?The local mailbox shows that the email was sent.Mail.log shows that the message was delivered to the mailbox.
