Hi,
We have some problems with sending mail with the SMTP service on IIS
(Windows 2000). We use the ASP.NET platform and have an ASPX-page that sends
different mail messages to about 1000 clients.
After some tests we found out that in one test some messages didn't arrive
at all to the recipient. All logs state that the operation went nicely (no
errors, no bad mail in the mailroot, etc.). We suspect that the target mail
server (all messages went to the same server) blocked some messages (maybe a
spam-filter or something). Is this possible?
In one test the operation was aborted by a exception (after 960 out 1000
messages sent). The exception in below. Any idea what caused the exception?
Exception:
System.Threadin g.ThreadAbortEx ception
Source:
mscorlib
Message:
Thread was being aborted.

There are all kinds of reaswons why an email might go missing at the
receiving end. SPAM filters, Junk Email filters, dropped packets, and let's
not forget the end user deleting it by accident.
As for the ThreadAbortExce ption, that could be caused by the Application
recycling. It could also be caused by your code, if you're using Threading.

Is it always the same email addresses that do not recieve the message?

We couldn't repeat that test because it was done in a production environment
with live users. All the users were in the same mail-domain though. Some
users received their mail and some didn't. Other similar tests in a test
environment worked fine (apart from one that was interrupted in an
exception).

First off, if there is a better place to post for an answer to this
question, please feel free to point me there.
I have some very strange behavior happening with my System.web.mail objects.
I was able to run my application fine for roughly 1500 email messages. The
next time I tried sending mail, it stopped working with the message:

I have a web page that at the click of a button must send a bunch (1000+)

anyone tell me why it is so slow, or how to fix the problem?
To address this I am thinking of just creating a queue table to write the

Right now, I have a mysql DB of registered users. I have a PHP file

mailer) w/ personalized messages (also from the DB) to the users.
Right now I've only got a few e-mails it needs to send per day so it
only takes a second or two for the file to load/run, but this may...

I have a vb app that runs on a server. It periodically checks for rows in a
table that are ready to have data mailed out to clients. After it finds
row(s) that are ready, it emails the info out and then marks the rows as
having been sent. It all works fine except for one thing. There have been a
couple of times when the 2nd part chokes due to a conflict on the server.
The mail is sent out but it never gets around to marking the rows as...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
