RE: External Users, Exchange 2000, and Relaying

2001-12-12 Thread Ritch Roberts

For those interested, I fixed the problem I mentioned below by deleting the
SMTP Virtual Server and then recreating it.  I wrote down all the settings
in the old server before deleting it so I would be sure the new server had
the exact same settings.  The only thing I can figure is that something with
the SMTP virtual server was corrupt and recreating it fixed the corruption.

Subject: External Users, Exchange 2000, and Relaying

Before I installed SP1 I did not have the following problem.

I have external users who use Outlook Express to get their mail and use our
server to send messages.  On the SMTP virtual server if I have the radio
button under Relay Restrictions set to Only the list below and the check
mark in the Allow all computers which successfully authenticate... I get
the following error when trying to send a message:

The message could not be sent because one of the recipients was rejected by
the server. The rejected e-mail address was '[EMAIL PROTECTED]'. Subject
'', Account: 'mailhost.mobilefarm.com', Server: 'mailhost.mobilefarm.com',
Protocol: SMTP, Server Response: '550 5.7.1 Unable to relay for
[EMAIL PROTECTED]', Port: 25, Secure(SSL): No, Server Error: 550, Error
Number: 0x800CCC79

The checkmark My server requires authentication in Outlook Express is
filled.

I checked the archives and saw someone suggested putting the IP address of
the server in the Only the list below section and this did not help.  I
have tried both the external and internal IP addresses for the server
without luck.

Before I installed SP1 the configuration above worked just fine.  Now the
only way users can send messages is when I change the Relay Restrictions
radio button to All Except the List below  Obviously this leaves us open
to abuse.  Any ideas?

New Version of Antigen will have content filtering

2001-12-10 Thread Ritch Roberts
Title: Mannesmann vertraut bei Antivirus-Schutz auf Antigen von Sybari 








Orlando, FL (October 1, 2001)  Sybari
Software, Inc., the premier developers of Antigen, a comprehensive anti-virus,
content-management, and e-mail security solution for Microsoft Exchange, today
announced Antigen version 6.5 for Microsoft Exchange. Antigen 6.5 will provide Exchange
administrators powerful new features and capabilities including new content
management tools for subject line, sender, and domain name filtering,
MTA connector message scanning (including X.400 messages), and Named Scan Job
Templates. Enhancements to the Antigen user interface, Antigen Worm Purge, and
support for Microsoft's Virus Scanning Application Program Interface (VS
API 2.0) in the Exchange 2000 Server will also be included in version 6.5.



Antigen 6.5 for Microsoft Exchange enhances administrators'
abilities to proactively eliminate suspect e-mail and spam based on all or part
of its subject line, as well as by sender and domain name. This new feature
further strengthens Antigen's content management capabilities, which
currently includes the ability to filter attachments by filename, wildcards,
and by file type. Filtered messages and attachments can then be deleted or
quarantined for review and delivery at a later time.



"Sybari's
Antigen delivers anti-virus and security solutions for Exchange administrators
and is a valuable business solution," said Kevin McCuistion,
Exchange Group product manager at Microsoft Corp.
"We're pleased to work with Sybari
in delivering a comprehensive solution that will meet the needs of our mutual
customers.." 



Responding to customer demand, Sybari also
added support for X.400 message scanning in Antigen 6.5 via the Antigen MTA
scan job, which provides the ability to scan messages passing through the Microsoft
Exchange Message Transfer Agent (MTA) on an Exchange 2000 Server, including all
Microsoft Exchange MTA connectors (X.400, MSMail, cc:Mail, etc). The Antigen SMTP and MTA scan jobs employ a
server side event slink to provide scanning of the Exchange 2000 connectors.
This implementation provides the means for antivirus scanning and content
filtering at the connector level which does not compete with the resources
needed to provide protection of mailboxes and public folders at the Information
Store.



We started using Antigen right after we got hit by the
I Love You virus, and that's the last email virus that got into our
system, said Bob Schmidt, director of computer networks  systems for
Kemmons Wilson Companies. Antigen has been able to filter out every bug
thrown our way, and I'm looking forward to the added control and protection of
the content filtering technology in Antigen 6.5.



With Antigen 6.5, administrators can easily customize the defaults for
scan jobs and establish custom Job Templates and File Filter Sets. Sybari has enhanced the Antigen MultiInstall
utility to assist in the deployment and loading of named templates by allowing
customized configurations to be included when the product is distributed
throughout an organization's messaging infrastructure. 



Sybari designed Antigen 6.5
specifically for Microsoft Exchange 2000 and Windows 2000 Servers, while
maintaining backward compatibility for Exchange versions 5.0 and 5.5. Antigen utilizes Windows 2000 Active
Directory service (ADS) to gather real-time information about Exchange Storage
groups and for notification alert purposes when viruses are detected or files
filtered. Antigen 6.5 makes
extensive use of the Microsoft Virus Scanning Application Program Interface (VS
API 2.0) for comprehensive and reliable antivirus protection and
content management of Exchange 2000 environments. Microsoft's VS API 2.0 provides
Exchange antivirus developers a versatile, low-level API for creating high
performance solutions.



"We are
very happy with Antigen. It's sleek, fast, and it works!, said Botp Pena,
System Adminstrator at Delmonte. We are one of many who asked
Sybari for subject and body text line filtering and are looking forward to
version 6.5 and the added security features.



Antigen for Microsoft Exchange is a server-level antivirus solution that
protects both Exchange 2000 and Exchange 5.5, delivering multiple virus scan
engine support with five of the leading scan engine technologies from Network
Associates, Sophos, Norman Data Defense, and the
Entrust antivirus engines from Computer Associates. The multiple scan engine manager is available for all Antigen scan jobs, and allows
administrators to customize and configure a variety of settings and options at
each level. Antigen 6.5 includes
two robust content management features:
Antigen File Filtering(tm) (AFF) and Antigen Worm Purge(tm). AFF enables administrators to
proactively filter e-mail based on several filters including subject line,
attachment filename, wildcards, and by file type. Antigen Worm Purge(tm) is a proactive
safeguard tool against worms burrowing into e-mail 

Restoring Inbox

2001-09-26 Thread Ritch Roberts








I am using Veritas 8 to back up my Exchange server which is
running 5.5 SP 4. Today I tried to restore
a mailbox for a user who lost all his mail while trying to use Outlook Express
on the road and each time I restore it puts all the messages in the calendar. I know they are in the calendar because
an unread number appears next to "calendar" in the folder view and
the calendar in now 25 MB. Not to
mention after the restore the inbox is empty. Has this happened to anyone else
before? Does any one know how to
move messages from the calendar to the inbox? Thank you in advance for any input you
might have.
