clr 2.0 missing in iis log (& broken app)

[frank]

We created an asp.net 2.0 app, which sends smtp email using System.Web.mail.
The app is in an IIS 6 application pool isolated to 2.0 apps on a 2003
server.

The app worked fine for a few days; recently however it began failing when
sending to external addresses (it works fine if the recipient is inside our
internal domain).

Comparing the logfiles, I notice when it was working both versions of the
CLR appear in log entries, for example:

(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1;+.NET+CLR+1.1.4322;+.NET+CLR+2.0.50727)

Log entries from when it fails only contain CLR 1.1, for example:

(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1;+.NET+CLR+1.1.4322)

The app is configured to use ASP.NET 2.0. What would be causing that
version to disappear from the log entries (and presumably the app) like
this?

That is the header from the client (i.e. the client only had version 1.x). I
think you are barking up the wrong tree.

Please cut down your crossposts in the future .. you hit several
irrelevant newsgroups, such as the .inetserver.asp.general group which
is focussed on classic ASP. The groups containing "dotnet" as part of
their names are the only relevant groups for your question

OK thanks; back to the debugging board... -fgb

The SMTP service has its own Log. If it not turned on then enable logging
and see what is happening. Do you see any entries in the badmail folder. You
should also check with your Exchange Administator (if you have one) to see
if they are blocking any emails. You can also configure your SMTP service to
send underlivered emails to an alternate email. You may get more information
from that.
