SBS2003 Server Performance Report email gets corrupted

  • 772

This is a problem I have had for some time, but it has until now been considered relatively minor (by myself and my colleague) so we haven't really tried to fix it. However, a couple of weeks ago an unfortunate series of events could have been avoided if the Server Performance Report email for that day had been legible, so now we have decided to try and fix it.

The problem is that every so often, in a seemingly random manner, the Server Performance Report email comes through as an un-decoded multipart MIME structure, like this:

This is a multi-part message in MIME format.

------=_NextPart_000_0000_01CCB4A5.81987E80
Content-Type: multipart/alternative;
    boundary="----=_NextPart_001_0001_01CCB4A5.819D3970"


------=_NextPart_001_0001_01CCB4A5.819D3970
Content-Type: text/plain;
    charset="utf-8"
Content-Transfer-Encoding: base64

CgkNCg0KDQoNClN1bW1hcnkgZm9yIFNFUlZFUjAxDQoNCiAJU2VydmVyIGhhcyBiZWVuIHJ1bm5p

...and so on...

When I view the message options in Outlook, I find that the boundary for the outer structure has been stripped from the Content-Type: header (which is obviously the reason it cannot be decoded) - here is a direct copy/paste of it:

Content-Type: multipart/related;
    boundary=

...BUT, this only happens about 40% of the time. For example, todays came through fine, yesterdays and Tuesday's were broken, Monday's was fine. Last week everything was fine all week. The week before, 4 were broken and 1 was OK.

I have looked through event logs for any errors, or a pattern of any kind that corresponds to when the emails are broken/not broken, and cannot find anything.

It has the feel of a problem caused by AV to me - we use AVG Internet Security 2010.

The Question(s)

  • Has any one ever come across this before?
  • Does anyone have any idea what might be causing this?
  • Does anyone know how to fix it?

TIA

    It looks like you are right, this problem is caused by AVG Antivirus. Quite a few people seem to have this problem.

    Exclude the following exchange directories from the AVG Resident Shield, the default path c:\program files\Exchsrvr:

    • Mailroot
    • CONNDATA
    • MDBDATA
    • MTADATA
    • SCHEMA

    (I took this from a forum post). Take a look at these links as well for more details:
