Make sure email scanning of your antivirus software is turned off. See

Also, what is the size of the attachments? It could be due to the large
size if they are several megabytes.

When I try to send an attachment, either a file attachment or through my
Epson Scan to email, the message looks as if it is trying to go but seems
to get stuck. It then takes over the rest of the system, slows everything
down to a crawl, uses up all the virtual memory and refuses any commands.
I have to resort to an emergency shutdown. On restarting the system checks
the files on the C Drive for consistency. While the problem is there the
msimn.exe on the taskbar rises very rapidly and the cpu memory rises and
falls rapidly.
Can anyone help?
