Re: [Declude.JunkMail] OT: Issues with Windows 2003 FTP service

[Matt]

Sandy, I have a lot of interest in finding a workaround to the thread issue, and no doubt this has promise.  I'm just saying that I'm reserving judgment until it is tested.  I will probably test it myself later today since Peter didn't respond yet to your post.  If you have some suggestions for what to set these registry values as, please don't hesitate to post them here or on the o.e.support group. Regarding the MS SMTP tarpitting, this was figured out long before issues with that client that turned out to be related to the interaction of IMail and MS SMTP.  The MS SMTP tarpitting issue is much more widespread.  Certainly it doesn't make sense to delay a 552 response when tarpitting, and either the delay itself, or the fact that this is combined with MS SMTP sending the response out of sequence, produces very understandable issues.  When I disabled this tweak, almost all of the issues disappeared immediately.  The only remaining issues are ones specifically related to the out of sequence response from MS SMTP, but they are much less frequent than what I was seeing.

There is a whole thread on this where Peter confirmed the affect on FTP (but not IIS) in VamSoft's o.e.support newsgroup, which I see you found after sending this message. Peter is very smart developer, but not a systems guy. You probably noticed our back-and-forth about ORF's 64-bit support. During our off-list continuation, I was struck equally by his lack of facility with certain common OS features (such as COM+) and yet the expertise with which he built ORF for scaleability and performance. I don't expect him to do in-depth tweaking outside of his app (and I'm sure he didn't touch these parameters here). I personally would be surprised to see a fixed (non-tweakable) thread limit, but I can't make a judgment without some form of verification of your suggestion considering the guidance that I was given (I'm not the programmer nor the expert). Tweak the settings and open up a lot of sessions to your server; you will see that the number of worker threads (as opposed to I/O ports) that can be created rises accordingly. Regarding the MS SMTP tarpitting, you have to trust me on that, or at least test it yourself before suggesting that I am wrong here. I'm sure you _are_ seeing aggravated problems with tarpitting enabled. Yet it's clear that you've observed problems with oversize messages _whether or not_ tarpitting is enabled, and you treated that fact insufficiently, it seemed to me. >From what you wrote, it sounds like running the sink that I wrote for the non-tarpitting server would solve both problems. As you may have noticed, it generates a DSN that does not include the original message, just the subject line, the message size, and the size limit. --Sandy ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. e-mail: [EMAIL PROTECTED] SpamAssassin plugs into Declude! http://www.imprimia.com/products/software/freeutils/SPAMC32/download/release/ Defuse Dictionary Attacks: Turn Exchange or IMail mailboxes into IMail Aliases! http://www.imprimia.com/products/software/freeutils/exchange2aliases/download/release/ http://www.imprimia.com/products/software/freeutils/ldap2aliases/download/release/ --- [This E-mail was scanned for viruses by Declude EVA www.declude.com] --- This E-mail came from the Declude.JunkMail mailing list.
