Email Spam/Virus Gateway
Dec 11, 2006Several companies like Fast servers and the planet provide spam filtering mail gateways (Spirus/ Barracuda etc).
Are there any reliable affordable 3rd party services out there as well?

I want to set up a dedicated server for spam and virus filtering (MX)
But i was wondering, is there a good opensource based tool for this?
We have a Windows Server 2003 dedicated, and use the Windows POP3 Service for emails, is there anything that can be plugged in to provide serverside spam/virus protection?

View 3 Replies View RelatedWhat type of free email scanner gateway that you are using? I am using SA, Clam and Qmail. It's a little old and w/o the GUI for client to manage the settings.
I'm thinking to switch to something with GUI. Perhaps the combination of Exim, SA, Clam, MAilScanner and a GUI.
It is possible to have anti-virus and anti-spam enabled by default when we go to "CREATE E-MAIL ADRESS" -> "SPAM FILTER" / "ANTI-VIRUS" is always disabled.

we are unhappy about sending mail and it goes to spam box.
but we see that some website send many mail. for examle they have 1,000,000 user and send email to them every day.but their email send to inbox
what can we do about it?
One of my clients is trying to send an email to someone who has barracuda spam filter on their systems. the spam filter is rejecting the email and marking the IP address as poor.
The IP address that it is rejecting is not the address of the SMTP server but the PC address (Outlook client). is this normal to check the client pc IP address and not the SMTP server?
The response from the spam filter includes a link to check the IP address which reports the IP address status as "poor".
The problem is this IP address is a dynamic IP assigned by the clients ISP. I tried a couple of IP addresses within the same subnet and they all seem to be marked as poor.
Does anyone have any suggestions on how I can fix this issue?? I have included the (masked) response from the spam filter below:

I have a dedicated server in which i host 4 web sites using plesk one of them is mysite.com. That one is also set for ns1.mysite.com ns2.mysite.com.
(all domain names below are just example names)
Dns records for my apple.com orange.com and banana.com uses ns1.mysite.com and ns2.mysite.com my name server is also in the same machine.
In orange.com dns settings are as follows.
Code:
80.111.11.11 / 24PTRorange.com
orange.com.NSns1.mysite.com.
orange.com.NSns2.mysite.com.
orange.com.A80.111.11.11
orange.com.MX (10)mail.mysite.com.
orange.com.TXTv=spf1 a mx include:gmail.com,yahoo.com,hotmail.com ~all
ftp.orange.com.CNAMEorange.com.
mail.orange.com.A80.111.11.11
webmail.orange.com.A80.111.11.11
www.orange.com.CNAMEorange.com.
80.111.11.11 is dedicated ip for orange.com.
The PROBLEM:
The thing is whenever the server sends email it is flagged spam by yahoo, hotmail etc. I have created SPF for my orange.com but it is still marked as spam...
I have checked dns report for both mysite.com and orange.com but they seem to be OK with no warnings either.
I want to create a spf record or make somthing so the emails does not marked as spam.
I received many email spam recently, with the sender address from my own server.
Eg.
my domain = www.shashinki.com
email spam that I received = shop@shashinki.com which is being sent to my own email address of shop@shashinki.com. Yes, the sender is my own email address account.
I checked using gmail and the sender is from my own server IP address and the sender's email address seems to be valid and is from my own email account.
I have changed the password of my email address, added SPF to my email system...etc. I have done all that I can think of, but I still get the same spam emails.
What can I do and what should I do? I got really tired of this and I am worried that my server is being used to send spams to others.
My server is with LayeredTech, unmanaged server, so I dont have a manager to help me.
Hope to get some insight and help from sifus here...
i have been receiving lot of spam emails with from and to address being the same email of my domain with content being "click here to see web page" or an image link of viagra shop seen. sometimes it is sent with title "delivery status failure"
i checked the mail headers and it seems that they do not originate with contact form since i used captcha to protect them.
I currently have a problem with my websites email going to spam. Most of the mail my website sends out, responses to registration, lost passwords etc...gets sent to spam. I have never used this site to send mass email or newsletters. I was thinking of getting an external hosted email solution, but wanted to know what you thought is the best solution for this and what you use to send out emails from your site.
View 4 Replies View RelatedOne of my servers is being used to send spam. The spam is coming from nobody@server.mydomain.com
I've found one user who's account was sending spam emails by using what i found @
[url]
However now i don’t seem to be able to stop the issue the same way as the log file does not contain the account being used anymore.
If there anyway i can stop mail being sent from nobody@server.mydomain.com completely? or even better only allow mail to be sent from valid email accounts on the server?
I work at a small startup. We have a database of contact information that is available on a subscription basis; people signup up and can download a limited number of contacts each month.
A core part of our signup is to send an activation email to the client. The email has a link back to our site. Clicking on the link activates the account and allows the client to log in.
Sometimes -- not always, but probably 20% of the time -- the client's email server will reject our activation email as spam. We see this alot with hotmail clients, and occasionally with others.
We're able to reproduce the problem. It appears to be an issue of the mail headers rather than the email content. I think it's related to the way we have our internal email configured: our email is hosted at Network Solutions, but we send the activation emails from our server at LiquidWeb. The activation email specifies a 'from' address that includes the domain that NS hosts.
My questions are: would this configuration cause email recipients to identify our email as spam? Short of moving our email server mgmt to our LiquidWeb server, is there anything we can do to avoid this issue from causing our email to look like spam?
I just found that some spammer send email through my server. I am using sendmail.
So if they know my domains in /etc/mail/local-host-names, can they spam email through my server without knowing username and password?
Do you think postfix is a better solution? The server is used by me only. I even won't connect to the server to sendmail. I use web mail to check email in the server.
My web development company has just launched a new website in Hong Kong.
It's a brand new site, so obviously hasnt even been listed on google yet.
One MAJOR problem we're facing is ALL email sent from the server is going to Spam/junk mail folders. We dont have a dedicated mail server and all mail is being sent via the web servers localhost (via a phpmailer script)
The site is member driven but members cannot join the site, because their account activation emails are going to spam/junk and theyre not finding them (we do mention for people to check their spam/junk but alot of people still dont)
So i am wondering if anyone has any tips how i can get the site listed as not spam. its a .hk domain name so i'm wondering if its only because im in australia that its going to spam for me?
either way id like to get the problem solved quickly, so if there is any verification/testing i can do to approve the site i would appreciate to find out.
I just got a vps and I realised that all email sent to hotmail automatically goes into the spam box (until i approve an email address as being "safe").
I believe that hotmail's senderid and a spf record is the way to go
I have already submitted the senderid form saying i dont have an spf record
for the "domains to be added to the senderid program", i listed a couple of my domains.
1) do i still need an spf record?
2) in the future, will i need to tell customers to use outgoing mailservers under one of the domains i submitted (in the senderid form)?
How can I prevent spam email to be send out by my servers?
How can I restrict how many emails per hour can be send based on domain name? I know hostgator and hostmonster has that type configuration.
I have SpamAssassin on my server, and I use email piping to forward incoming emails to a PHP script. I'd like to know if emails go through SpamAssassin before being piped, or if they don't go through SpamAssasin. Where exactly is SpamAssassin requested to scan emails?
View 5 Replies View Relatedway to send up to a few thousand emails per day.
These emails are simply replies to people contacting me first then I reply with ONE message from an autoresponder. No further contact is made unless they write me back again.
This is not really something that would work with aweber, getresponse, or a similar service.
And most email service providers seem to have a limit of 250/messages a day.
I'm guessing I will need a dedicated server for this?
Anything else I need on the dedicated server? I only have a few mailbox accounts I use that I access via outlook.
One of my clients is receiving spam from his email address. SpamAssassin is not marking it as spam. I have added an SPF record for the domain, but still gets these messages. Is there any workaround for this? I don't want to activate spambox for that.
Server is cPanel + CentOS 5.2
We have a script that will be sending out emails from our server. A few already have hit the Outlook SPAM folder. The email that's sent is a validation check, where the user has to click a link to verify an account.
Is there some service out there where you can send it your email and it will tell you if and then why it will be caught by leading spam filters?
I'm just working with my first dedicated server and also in the process of coding a new site. Anyway, I've gotten around to emailing users from scripts on my site (Java Servlet). Using Sendmail as the server (with default config) the emails are detected as spam by pretty much everything.
I'm looking for a complete list of things which need to be done to ensure an email isn't detected incorrectly as spam. I've read through various sites etc but haven't found a definitive list of things which should be done. I'm sure this would be helpful for other forum visitors too.
I'm NOT trying to send spam or anything like that but I haven't set up a dedicated server before.
One of my clients believes someone is trying to get revenge on him. His email box is being filled with bounced messages (around 6-8 per minute) primarily from one location.
Looking at the headers it's difficult to tell whether there is a script on his site that is being used for mass emailing but it doesn't seem like it since a good deal of WHM doesn't show it and many of the return messages are lucy1@domain.com, lucy2@domain.com, etc. so they are autogenerated.
What do you guys do to check which shared account is doing mass sends? This guy insists that no scripts on his domain are doing the sending and that it's routed to his email address, e.g. revenge. WHM doesn't always specify (it seems) which account is actually doing the sending (mailnull). Any way to separate this better? Also, if he's right, what do you do about it? Right now he's got all the bounces going to his junk mail.
I just installed the latest version of PHPList (Email manager program) on our client's dedicated server. The dedicated server is using Linux with Apache and PHP version 4.4.4.
When I try to subscribe to the newsletter I am suppose to receive a confirmation email.
Unfortunately my company's email host blocks this email thinking it's spam and I so I never receive the confirmation email. I then installed the exact same version of PHPList on a shared server with Linux, Apache, and PHP 4.4.4. Using this setup I received the confirmation email.
So it seems like the server is the problem and not the software. The IP address of the dedicated server is not blacklisted. Actually the IP address just came into existence in January 2007.
It really makes no sense to me why emails coming from the dedicated server are marked spam, but emails coming from the shared server are fine. Both servers are hosted by Hostgator.
I am clueless as to what action to take next. Are there any server settings that could fix this problem? Any ideas is greatly appreciated.
I have a VPS and I am wondering if anyone knows any way in which to make it so that emails sent from the server are not seen as spam by hotmail and the likes.

A user in my server trying to send email, but email is flagged as "Absolute Spam" by Spamassassin. It says IP is listed in SBL/XBL.
There is an IP address in "Received-From" part of the headers. That IP is actually listed in several spam databases, but not my server's IP (Below, red and bold).
Email is sent from my server, but how come "From" IP is different from mine?
