There is Hope in E-mail Anti Spam And Virus Protection For Corporations By : Cheryle C. Hayes With anti spam sellers offering lower cost licensing, companies can now afford sophisticated email spam and pathogen protection with an simple straightforward to use interface at a much lower cost. The best thing about technology is that as it evolves it is getting faster, extra features and cheap. Over the past few years the same evolution has taken place with anti spam technology and services. Largely this can be accredited to the open source software community and enterprising firms enhancing the capacities of this program and packaging it into simple to use anti spam appliances. It isn't practical to have anti spam software running on desktops in a networked business environment. Handling all employee junk email software at the desktop is not pragmatic. It could be a nightmare and costly in terms time and licensing. Spam appliances sit in front of your email server so that when e-mail comes in it will first go to the spam appliance and the e-mail will be scanned for spam as well as viruses. The filter will block the message if it identified as know spam. If the filter isn't sure if the email is real it'll quarantine and hold the e-mail at the filter and it'll be stored till the recipient removes it, releases it to their e-mail box, or they can white list a reliable correspondent so that future emails will not be held back. This could greatly reduce the load on your e-mail server and reduce your bandwidth needs. We have seen anti spam systems block up to 83% of incoming messages. This can help extend the life of your e-mail server and push back the need for upgraded capacity. Most virus outbreaks occur through email and for small cost an appliance can block viruses before they reach your network and users inboxes. This provides an additional layer of defense in addition to your current anti virus solution. Companies have 2 options if they use an appliance based solution for their spam and pathogen control. They can get and administer their own filter. This is a good option if you've got a enormous number of worker mailboxes to guard and the technical staff to administer the spam appliance. Companies also have the option to outsource their spam control as a hosted service. This is a good selection for smaller firms and if information technology is not your specialty. if you purchase your own spam filter, a subscription to updates may also be needed. Make sure you get upfront pricing for the add-ons that you're going to need. If you have more than 100 email users and the technical staff to maintain the spam appliance, buying your own filter may be your best option. Generally the basic model will work for most affiliations. Large bodies with thousands of users will require a spam filter appliance with increases capacity and features. Spam appliances are engineered to work with all mail systems but some do have express enhancements for Exchange server Microsofts preferred collaboration software and mail servers that support LDAP ( light weight index access custom ). Spam appliances use the LDAP custom to determine recipients before delivering messages to your e-mail server, this avoids consuming server resources. If your business has five to one hundred employees, then an outsourced anti spam and virus filter service is going to be a good economical choice for your organization. Charges are based on the number of users and you only pay for what you use. You will not have hardware to buy, maintain, and upgrade. The upfront cost is marginal and most e-mail filtering providers will let you try the service for free initially. Another added benefit to outsourcing your spam control is redundancy. It is important that you choose a provider that has their spam and virus filters collocated at secure net data center facilities. Information centers provide redundant network connections and power, so if your email server or net connection is down surprisingly the spam appliance will hold your email until your e-mail server becomes available, minus spam and viruses. Anti spam technology is consistently improving and the costs are getting lower. With increased productiveness and an added layer of defense against pathogen attacks, an anti spam appliance or service is something your business can not afford to be without.

The Cost of Running and Configuring an Exchange Server By : Thurman C. Arzola An exchange server is a Microsoft function that serves a variety of purposes including email capabilities, calendar application and information storage. Exchange servers have been available since 1993 and have proved to be an incredibly popular facility. There have been many versions since their introduction to cope with the increasing demands of new operating systems in the world of personal computing. When configuring an exchange server, it's a necessity to set up individual e-mail accounts for each individual which will be using the facility for sending and receiving messages through the server. Each individual account must be configured to allow varying levels of accessibility, therefore giving some users higher degrees of permission than others. This designates what particular levels of access people could have on the server and dictates the level of control that a particular user will have over their own e-mails. Once set up, the moderator or director of the exchange server is able to configure the filtering options. This can offer protection from viruses, trojans, spam and unsolicited mail reaching the users of the post facility of the exchange servers in question . Individual IP addresses can be blocked to stop mail coming from one special person and the server can also block recipients so messages can't reach them. Once a message has cleared the filtering system, it is routed to the proposed recipient. Microsoft exchange servers were originally designed to be used only with Microsoft Outlook, but the inflating numbers of versions have allowed other clients to be used including Outlook Express, Mozilla and Thunderbird as well as allowing interfaces like Outlook Web Access. The latest version of Microsoft exchange server will be ES2010. This is lined up for release in the later part of 2009 and will contain a major number of new features as well as improving certain aspects of the ES2007 version. Price can vary dependant on the amount of storage groups and databases required. Cost can also be affected by the relevant licenses needed for operation. 5 storage groups and equivalent number of databases per mailbox server role will cost $699 ( Standard Edition ) while fifty storage groups and fifty databases will cost $3,999 ( establishment Edition ). the standard license costs $67 while an upgrade to a co. license adds $35 to the bill. External connector licenses will alter in price from area to region but may not be affected by restrictions. These licenses are generally charged out at individual price per server.
