Title: RE: Antivirus API We use OpenRetryDelay of 0x800 here with no problems (touch wood). The default set by the GroupShield install is plain wrong.

We do see the error every so often with very large attachments, but they are few and far between. We are using NT4 SP6a, Exch 5.5 sp4 and Groupshield 4.5 from NAI.

RE: Antivirus API
Title: RE: Antivirus API We use NAV with exchange 5.5. Once we setup the NAV to do background scanning the problem you have went away. We were able to keep the MAPI/VAPI mode running. With only the MAPI mode running on NAV you can get some virus' get through the NAV scans. If at all possible you should try to keep the VAPI mode enabled.

RE: Antivirus API
I realize you're talking about 5.5, however Exchange 2000 supports VSAPI 2.0 which doesn't require MAPI to scan emails. Any and all emails are scanned before entering the information store. Since switching from Exchange 5.5 to 2000 SP1 w/ Norton AV for MSE Version 2.5 (build 11) I haven't had any problems. I used to get a lot of quarantines of emails from unknown sender to unknown recipient, which I don't get anymore. :) Trend and Sybari also get great reviews. This message is in MIME format. Since your mail reader does not understand this format, some or all of this message may not be legible. --_=_NextPart_001_01C15CB6.3C737F50 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: quoted-printable Our implementation of NAV for EXCHANGE SERVER 5.5 has the exact same = issues using the VAPI option.. we switched to MAPI Only and all problems went = away. -Rick -Original Message- From: Ropiak Steve - NAO Florence Office Exchange and Bar Code Admn.
