[Declude.Virus] OT: Hardware recommendations
I'm going to be upgrading from an old version of iMail to a current one, and go with Declude Virus and either Declude Junkmail or a seperate IMGate-MTA type solution. So I'm about to order up the new imail-Declude machine and it looks to me like I can either go with a dual processor P3 (probably 1.2GHz) with 512MB PC133 RAM or a single P4 2GHz or so with 512MB DDR . Given that the storage will be the same (Promise RAID controller with 2 7200 RPM 80GB drives) I wonder if any of you have any thoughts on what would be the better choice. Thanks for any feedback and I hope this is an appropriate topic. I would have gone to the iMail list, but since it will also be running the Declude product --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] This E-mail came from the Declude.Virus mailing list.

RE: [Declude.Virus] OT: Hardware recommendations
I recommend going with the single processor. Recovery in the unlikely event of a main board failure is MUCH easier. Not to mention it will be easier to support a P4 in future than a P3. You're likely to be IO bound more than anything else - so concentration on your storage is important - if you have to make a trade-off, make it in favor of faster storage or better caching therein. Also, watch out for your nic... It's a small thing, but the speed and reliability of that piece can make or break a mail server. These days memory is cheap... There's almost no excuse any more to have less than 1G in Ram (IMHO) not because you need it now, but because not having it is always worse than having it. This can come in handy when running multiple instances of command line virus scanners or other programs like Message Sniffer. The extra ram also helps when caching these programs and their data - if the box doesn't need to hit the hard drive for this you'll be in great shape. Along those lines, if you want to get clever (or beg for trouble based on your point of view) you might even tweak things a bit by putting your spool directory in a ram-disk... But don't go that far unless you want this box to carry heavy traffic and your power and equipment are stable enough that you won't worry about the spool dir going away. Hope this helps. I'm sure others have different viewpoints to add. _M | -Original Message- | From: [EMAIL PROTECTED] | [mailto:[EMAIL PROTECTED]] On Behalf Of Dan Rapaport | Sent: Monday, June 10, 2002 2:46 PM | To: [EMAIL PROTECTED] | Subject: [Declude.Virus] OT: Hardware recommendations | | | I'm going to be upgrading from an old version of iMail to a | current one, | and go with Declude Virus and either Declude Junkmail or | a seperate | IMGate-MTA type solution. | | So I'm about to order up the new imail-Declude machine and it | looks to me | like I can either go with a dual processor P3 (probably | 1.2GHz) with 512MB | PC133 RAM or a single P4 2GHz or so with 512MB DDR .

Re: [Declude.Virus] Outlook 'CR' Vulnerability
Can anyone tell me what the [Outlook 'CR' Vulnerability] is and where to fine information on it to give to the customer. I am running f-prot 3.12 as the scanner The issue is that there is a header with an illegal character in it (a carriage return, rather than the carriage return + linefeed that indicates the end of a line). There is no valid reason to have such as character in the headers, and it violates RFC specs (and would be reason to fail the BADHEADERS test in Declude JunkMail, although that is not currently tested for). Having such a character in the headers causes a fork in processing the E-mail -- some programs (AV scanners or mail clients) will handle the headers correctly, others (Outlook) will not, and will process the E-mail very differently (with extra headers that don't really exist, without headers that do exist, and even creating non-existent attachments with very real viruses). As a result, having such a character bypasses security mechanisms. http://www.openoffice.nl/special_interest/outlookbug.html has more information on this issue. -Scott --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] This E-mail came from the Declude.Virus mailing list.

Just out of interest: How would you go about putting your spool directory in a RAMDisk?

You'll need this: http://support.ipswitch.com/kb/IM-19990908-DM01.htm And something like this: http://support.microsoft.com/default.aspx?scid=kb;EN-US;q257405 (a toy) Or http://www.cenatek.com/product_ramdisk.cfm (much better option) http://www.winsoft.sk/ramdisk.htm (also good I hear) Hope this helps, _M PS: There are a lot of ramdisk options out there as google will show. | -Original Message- | From: [EMAIL PROTECTED] | [mailto:[EMAIL PROTECTED]] On Behalf Of Craig Gittens | Sent: Monday, June 10, 2002 3:42 PM | To: [EMAIL PROTECTED] | Subject: RE: [Declude.Virus] OT: Hardware recommendations | | | Just out of interest: How would you go about putting your | spool directory in a RAMDisk? | | | Craig. | | -Original Message- | From: [EMAIL PROTECTED] | [mailto:[EMAIL PROTECTED]]On | Behalf Of | Madscientist | Sent: Monday, June 10, 2002 3:17 PM | To: [EMAIL PROTECTED] | Subject: RE: [Declude.Virus] OT: Hardware recommendations | | | I recommend going with the single processor.
