Server :: Spam/virus Fetchmail Option

Oct 7, 2010

My client has finally had enough of being attacked via SPAM/Viruses and having his single email account for his company being destroyed. Since it is a single account and he does not want to add additional accounts or create a new one(mail is hosted by ISP), I wanted to ask the forum on their opinion on using Fetchmail to download the POP3 mail and having it piped through SMAM Assassion or DSpam and or CLAM_AV or F-PROT. In addition to that I am going to use a corporate strength anti-virus such as F-prot(Been using for years) and really put this email through a microscope. I also was thinking of just blocking out all domains other than his clients list of domains so in other words block all and allow just the domains that we know are valid and are only from his clients. It is super restrictive but what I believe will end his issue.

Fedora :: Linux Fedora Anti-Spam & Anti-Virus Server Solution Needed

Apr 25, 2010

I want to setup a Linux Fedora based Anti-Virus & Anti-Spam Server on my LAN. I have more than 60 Windows users with Proxy Squid running on LAN. Our Email server is hosted on the Internet. Because of virus/spam generate problem, emails are worst affected & the users have a lot of problem on Email, as the outlook gives error. It happens when a PC generates Spam & our IP gets blocked by the ISP for some time. Thats why I want to setup an Anti VIRUS/SPAM Firewall on my LAN (before the Squid), so these spams do not go past the Internet Gateway.Hope u guys understand my problem & suggest some useful links, software & documentations.

Server :: Sending Spam To The Spam Folder?

Apr 30, 2009

I just setup SpamAssassin and what not following this tutorial

[URL]

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

Because our visitors/customers are short term, and may be configured incorrectly with their own mail servers we automagically redirect all port 25 traffic going to internal IP's to our own mail servers while on our network.(postfix on centos 5.6)While I have taken some measures to prevent it from spamming, I would greatly appreciate some assistance.I will be putting in clamav, but I haven't configured it yet with the mail.I am using postfix, but can also put on procmail or even spam assassin

Server :: Roaming Users Getting Flagged As Spam On Server?

Apr 16, 2010

Amavis-new on my mail server is marking my emails as spam, like so:

Quote:

Apr 16 12:15:52 myserver amavis[30979]: (o3GIFltt008868) Blocked SPAM, AM.PDP-SOCK [xx.xx.xx.xx] [xx.xx.xx.xx] <myemail@mydomain.com> -> <myfriend@hisdomain.com>, quarantine: spam-w1hxRn9Pr4P6.gz, Message-ID: <4BC8A9E8.2070108@mydomain.com>, mail_id: w1hxRn9Pr4P6, Hits: 7.844, size: 6763, 1986 ms

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?

Server :: VPN Is Being Used In Sending Spam

Jul 3, 2011

We have a vpn that is accessible to anyone. We already block port 25, 587 and 465. But I am still receiving spam reports. I believe that the users of my vpn is infected by a virus or something that sends spam. Are there any other ways that spammer send spam mails without using the smtp ports?

My guess is that they are trying to send it by accessing a webmail. Have you heard of anything like that? how to block spam?

Server :: Fetchmail - Downloading Messages From Gmail Account

May 22, 2010

I need to ask you how canIi make some fetchmail jobs to download mails from my gmail account into my mail account in my own server? My server is :
Linux Centos 5.4
Postfix Mail Server

I make a file named .fetchmailrc in my home directory and set its permissions to 755and the content of this file is:

set postmaster "postmaster"
set bouncemail
set no spambounce
set properties ""
poll imap.googlemail.com:993 protocol imap username "username@gmail.com" password "password"

I think something is not completed, I need to make that fetch to a specific user only, not all users.

Server :: Configure Fetchmail To Use Passwd For Local Delivery?

Jul 6, 2011

The common wisdom seems to be to setup an SMTP server (say postfix) so that connections either coming from the same host or where the end delivery is local can do so without using any authentication mechanism.

This will for example allow fetchmail to deliver fetched mail locally on port 25 (without logging in) for any user.

However, what if I setup the SMTP server to force every incoming connection to be authenticated regardless if the end delivery is local or relayed and regardless where the connection comes from.

Is it possible to configure fetchmail to use a password when doing the local delivery?

(I haven't been able to find any such configuration options in fetchmail.)

Software :: Configuring Fetchmail - Mail Server Setup

Aug 6, 2010

I have Ubuntu and I want to setup a mailserver. I use fetchmail to fetch mail But I wanted to configure fetchmail with fetchmailconf. I know, I can edit the configfile, but I wanted to use fetchmailconf. According to the man of fetchmail, fetchmailconf is very handy.

In synaptic, I installed fetchmail 6.3.2.2Ubuntu2.3 and I wanted to install fetchmailconf 6.3.2.2Ubuntu2 : well it didnt work
fetchmailconf 6.3.2.2Ubuntu2 needs fetchmail 6.3.2.2Ubuntu2. So, no worries: I searched the internet for fetchmailconf 6.3.2.2Ubuntu2.3, but I couldn't find any. Same with fetchmail6.3.2.2Ubuntu2

First of all, I want to flame synaptic for supplying 2 different versions for 2 pieces of software that only work with eachother.
Second: where can I find 2 matching versions? Or fix synaptic or maybe someone has a really cool solution?

Server :: Server Side Spam Filtering

Feb 4, 2010

I have a mail server (dovecot+postfix) on Centos with amavis/clamav installed and working. It correctly identifies spam as such and puts it in the headers. I want it to move those suspected spam messages into a spam folder. I do have this working on an older debian server that I didn't setup. If someone could point me in the direction if where that config might be. I can't find it in any of the mail config files.Could there be a seperate package doing this?

Server :: Add Spam Header Into Email Messages?

Dec 19, 2009

I'm setting up email gateway using Postfix, Amavisd-new, ClamAV and SpamAssassin on Opensuse 11.1. Everything seems okie, but I can't have messages with added spam headers, such as:

X-Spam-Flag: NO
X-Spam-Score: 0.233
X-Spam-Level:
X-Spam-Status: No, score=0.233 tagged_above=-10 required=6.6
tests=[ALL_TRUSTED=-1.8, AWL=0.536, BAYES_50=0.001,]

When I try to debug amavis, I can see that SPAM-TAG, <abc@yahoo.com> -> <celeron@domain.com>, No, score=5.406 tagged_above=-999 required=6.2 tests=[LOCAL_DRUG=4, NO_DNS_FOR_FROM=1.407, NO_RELAYS=-0.001] but they don't add to email messages. I've configured amavisd-new with $sa_tag_level_deflt = -999 to add spam headers at all but not successful.

Server :: Enabling Transparent Spam Filtering?

Jun 2, 2010

I need to implement a form of filtering. Current topology is like so:

Internet -> Smoothwall -> MS Exchange server (w/ OWA) -> Clients

So I need to enable transparent spam filtering on the smoothwall system, which is a full fledged Linux system. There are no 'free' modules available for smoothwall that enable spam filtering. And due to the monetary constraints of the project I'm working on, something free is required.

I don't have any experience with this - I've done a couple of searches and came up with "SpamAssasin", but I can't find any relevant guides that allow transparent scanning - they all assume the mail is stored on THAT server.

So I'm here to ask the more experienced people what sort of packages will enable this functionality? Would like something that has a WebUI, but that's not absolutely necessary.
