Spam filter for email server

Depends on what you want to pay. There are various ways of doing this.
1. block at your firewall. I have a watchguard and this acts as my first line of defense.
2. Install an app on your mail server - I have Symantic for Exchange as my second line 
but then you can go and signup to outside organisations such as messagelabs to handle all your filtering for you.

hi all,
im running postfix+dovecot for an email server and i want a spam filter to go infront of postfix so it can filter out spam before it gets anywhere near my email server
also i imagine with spam filters you can set your own spam policies and allow good senders and block bad senders
many thanks

  • Is there a spam filter for email?

    Getting dozens of spam emails on iPad and iPhone each day.   Is there a filter available?

    Hi everyone
    It's been awhile since I last visited.  Good to be back.  I have a problem with spam on my @me.com account, is there any way to convert this into an @icloud.com account so I can relieve myself of this problem.  As we speak I am staring at 996 emails with the vast majority of them being spam(I really hate my brother!).  I would hate to lose all my purchased content because of this problem.  If Apple would allow me to change my primary Apple ID email account I could resolve it that way as well.  On the AppleID site you only get options to add alternate email addresses.
    Any suggestions greatly appreciated
    Thanks

  • Can I set up a spam filter for my iPad like I have on my Mac?

    Can I set up a spam filter for my iPad like I have on my Mac?

    The Mac OS X Mail application has a "Junk" function that works locally, on the Mac, and just puts emails from previously designated "junk" addresses into a separete folder, so you don't have to wade thru all that spam in your Inbox. It's a very elegant and simple, local solution, that I dearly miss on iOS.
    I did submit a request for it at Apple Feedback page.

  • The Best Spam Filter for Mail

    Here is the best smap filter for mail:
    http://c-command.com/spamsieve/
    I don't know why Apple don't buy that company and include the spam filter on mail, that would be great because spam is getting worst every day, and people than don't buy this type of spam filters need to delete a lot of spam mails every day.

    The Junk Mail filter included with the Mail.app has always worked very well for me, and IMO, a good deal of the responsibility for filtering spam in the first place and where it arrives initially, lies with the email account provider for an email account - with adequate filtering performed at the incoming mail server.
    This and taking some precautions with an email address shouldn't require having to purchase a spam filter from a 3rd party for the email client used to access an account.

  • Is there a Spam filter for Mail? In iOS 5?

    I haven't seen this question posted for a couple of years, so I'm curious if iOS 4 has addressed my concern. Can Mail for iPod Touch 4th Generation be set up with some sort of spam filter? I have very good filters associated with my various email accounts at their servers (Gmail, GoDaddy, Earthlink) but all of these accounts pass the spam through to my iPod.
    Will this be fixed in iOS 5?
    And also ... why do some messages not offer the "Trash Can" icon, but only the multiple button option to "Move to>Trash"?
    Thanks

    No. iOS5 isn't out yet. We don't know what's in it. But likely there isn't.

  • Spam getting past email server

    Why has my email server started letting so much spam get through?  What can I do to stop it?  Thanks.

    Your question is too vague.
    First off you need to realize you will not stop all spam. Mega-corporations have spent billions trying to 'fix' spam, so don't think you're going to solve the issue yourself.
    On that basis, the best you can hope for is reducing spam to a manageable level - at least as far as your users' mailboxes are concerned. However, you don't state how much spam you're getting... are you getting 1? 10? 100? 10,000 spam messages an hour? so it's impossible to tell whether you're in the realm of normal behaviour or not.
    You also don't state whether the spam is directed at your domain, or specific user mailboxes?
    Are some users getting more spam than others?
    Is the spam actually getting to users' mailboxes or is it getting blocked before it gets that far?
    Also, you state your server has 'started letting so much spam through', so the most pertinent question is what have you changed - these things don't radically change on their own so the chances are something's changed on your server that's having an effect.
    So, more data please.

  • SPAM from our email server

    I received an email from [email protected]
    Subject: Email Feedback Report for IP (our email server's IP address)
    This is an email abuse report for an email message with the message-id of F07FB3A7-2B7C-4DD7-BD3B-D976E24D398D@(ourdomain).com received from IP address (our email server's IP address) on Wed, 26 Oct 2011 12:03:22 -0400 (EDT)
    So it looks like SPAM was sent from our email server from the email address above (F07FB3A7-etc...).  I searched log files but I can't locate anything with that address.  There are no accounts with that name on the server.  Is it possible that someone created that account, sent out SPAM, then deleted the account?  I'm puzzled.

    Post the unexpurgated contents of the postconf -n command, and we'll have a look at the usual suspects.
    We'll also want a look at the headers from the feedback message, as well as the reported spam.  This to see whether the feedback message looks legitimate, and what the reported spam message contained.
    And search for the time of the message in the logs; that long hexadecimal string is in the format of a GUID/UUID valud, and not a user.   Which might mean it's tied to a message, or to a user.  (The message headers can show more about this.)
    (For the GUIDs associated with users, look around for a user in your Open Directory or your local database with a matching value.  This can be visible via Workgroup manager inspector, or via the GeneratedUID value that Directory Utility can display for the user.  For the messages, dig around in the SMTP server logs.)

  • Spam blocking for email accounts

    Anyone know how to block spam ads from email accounts?  I have both work and personal email accounts--spam only coming in on on personal.  I've installed Lookout Mobile Security, but doesn't stop the 7-10 product ads per day from coming into my inbox.  Verizon tech assistance was courteous and helpful, but wrong.  They're the ones who told me to install Lookout Mobile Security. It may work for antivirus, but doesn't stop spam.

  • Starting guardian process for eMail server

    I've installed a new database, with the standard settings given on the install CD, and the Oracle eMail server on a Windows 2000 os.
    The problem starts when try to start the email server node's guardian. I have to submit the Service Name, the database name in the TNSNAME.ora. When I try to save the value I get the following error message: "oracle.io.admin.common.PropertyException".
    What does that mean and what should I do to get the service running?
    Regards
    /Jonas Dannaeus
    null

    I have the similar problems.
    Conditions:
    I tried to install Oracle EMail Server v5.1 (the package was downloaded
    from these URL:
    basic: http://technet.oracle.com/cgi-bin/go?email51nt-full
    patch set: http://technet.oracle.com/cgi-bin/go?es51patch2nt )
    on the machine with the following configuration:
    Hardware:
    Intel Pentium III 600MHz, 512Mb RAM, 30Gb IDE HDD, 20Gb free on
    destination volume.
    Software:
    OS WindowsNT 4.0 Server Service Pack 4
    and following Oracle products installed:
    Oracle8i Enterprise Edition 8.1.6.0.0 (installation option - typical)
    Oracle Portal 3.0.6.3.3
    Oracle Internet File System 1.0.8.1.0
    Resulting messaging system must consist of one TCP/IP node, that is all
    EMail processes (possibly except Sendmail, see questions below) will run
    on the same machine. This node also must be the configuration node.
    Installation of EMail Server (default option - includes all products)
    performs well, installing server into the same OracleHome, as the
    Oracle8i Enterprise is located in.
    The configuration options are as follows:
    Create a new node
    Create a custom Email Server node
    Yes - this is the first Email Server node that I am installing
    Timezone selected - (GMT +3:00) Russian Standard Time
    Enabled servers:
    POP3
    POP3 using SSL
    Yes - I want to enable SMTP gateway on this machine
    Define and configure a new gateway
    No - I don't want to enable the LDAP access on this machine
    Yes - I have an existing database
    Further configuration, including creation of all needed database
    objects and Windows NT service (named OracleInternetMessaging<SID>),
    also performs nice.
    After these steps (installing and configuring) I tried to run
    OracleInternetMessaging<SID> service from Windows NT services window
    (Oracle database and TNSListener services were launched earlier).
    Launch failed with error message:
    'The OracleInternetMessaging<SID> service returned service-specific error 1.'
    Then I tried to start Email Server manually as described in installation
    guide (section postinstallation). ofcguard command reported that
    guardian had started, but command
    'ofcguard status'
    returned following string
    'Status down'
    When I inspected log file, located in directory %ORACLE_HOME%\office\log\<SID>,
    I found there following lines:
    01/11 13:12:00 INF: Guardian Version 5.1.0.1.51 started.
    01/11 13:12:00 INF: Logged into database.
    01/11 13:12:00 ERR: Failed to get database timezone information.
    What is the reason of these problems?
    Could you answer these questions also:
    1. In postinstall section of installation guide is written that setup
    makes changes in file tnsnames.ora. But I didn't found any changes
    in it. But setup placed in the directory
    %ORACLE_HOME%\office\admin\samples
    another file, that consists of old tnsnames.ora and several new lines,
    something like this:
    crocus.world =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS =
    (COMMUNITY = tcp.world)
    (PROTOCOL = TCP)
    (Host = crocus)
    (Port = 1521)
    (CONNECT_DATA = (SID = CROCUS)
    crocus_guardian.world =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS =
    (COMMUNITY = tcp.world)
    (PROTOCOL = TCP)
    (Host = crocus)
    (Port = 1521)
    (CONNECT_DATA = (SID = GUARDIAN)
    Should I place this new file instead my old tnsnames.ora (I did it,
    but it had no effect), or what shuld I do else?
    NB: Something similar occurs with listener.ora file.
    2. Problem with Sendmail: From Oracle Email Server installation
    guide I concluded that Email Server uses in its work Sendmail
    through properly configured SMTP gateway. The question is:
    Sendmail itself must run on the same machine as Oracle Email
    Server or it may run on another computer in the network?
    If Sendmail MUST run on the same machine as Email Server,
    then where I can get REAL Sendmail for Windows NT platform?
    I found several Sendmail's for NT, but all of them can only
    send messages from the command line. None of them is able to
    run as NT service to handle inbound and outbound mail traff ic.
    3. In the Oracle Email Server administration guide (chapter #19 -
    'Error Codes and Messages', item 'Messaging Server Messages',
    error DA-10505 - 'Could not start server processes.') the
    dbms_alarm package is mentioned. I don't have this package
    installed at the moment. I didn't find any references to it
    in Oracle documentation also. But my installation of Oracle 8i
    Enterprise now includes the dbms_alert package. Maybe dbms_alarm
    is a typing error and dbms_alert must be in its place in
    Administration guide? If I'm wrong and documentation is OK,
    then the question is: should I really have the dbms_alarm
    package installed and if so, where can I get this package?

  • GSS for email server

    Greeting,
    Could anyone advice me if GSS4492R can be used to email server infrastructure?
    If so, how to do it? how to setup MX record?
    Any comments will be appreciated
    thanks in advance

    GSS2.0 with CNR supports GSLB (Global server load balancing) of MX
    records.
    Here are the details
    Each query is processed as follows, depending upon its type:
    *A Queries- The GSS processes these queries and responds if it finds a
    reply for the query. If it fails to find a reply, it queries the CNR
    subsystem for a reply. The CNR reply is then forwarded to the D-Proxy.
    *All other Queries- These queries are forwarded to the CNR subsystem.
    The response from the CNR subsystem is forwarded back to the D-Proxy. If
    the response contains A records in the Additional Section, the GSS may
    perform its own query processing and modify the Additional Section of
    the Response to provide a load-balanced A records in the Additional
    Section.

  • Want to use OSX server as virus/spam filter for existing mail server.

    I have communigate pro completely configured and running on an iMac. hundreds of accounts, all working perfectly. The bummer is that the spam/virus filtering of Communigate Pro is weak, and I'd like to try the one built into my Xserve.
    Right now I have the domain company.com, with two A records for mail.company.com (the communigate pro server) and xserve.company.com (the xserve). And right now the MX record for company.com points to mail.company.com.
    I'd like to switch the MX record for company.com so that it points to xserve.company.com (which I know how to do). The xserve would then reject/delete/catch the spam/viruses and then forward on the remaining "good" messages to mail.company.com. The company.com clients would still get their mail from mail.company.com via Pop/Imap/Webmail.
    Any and all help is truly appreciated!!!

    imho... you may be over-complicating your system and adding additional points of failure to your architecture if you go this route.
    Communigate Pro allows you to run both SpamAssassin 3 and Clamd (the main antivirus/antispamspam tools provided in OSX Server) very easily on your CGPro box.
    MPP Free gives you a nice gui for configuring them.

  • Spam Filter for iPad?

    Is there a way to filter the iPad Mail app for spam?

    Selecting an email for deletion is not the equivalent to opening the email.
    You can select an email for deletion without opening the email.
    You can also turn Load Remote Images off. When remote images are rendered from a server when opening an email is how an email address is determined to be known good by a spammer.
