Just to follow up on this, I remembered that I had deactivated a number of Windows
services to free up some memory and speed up startup. So I went again to

Start -> Run -> services.msc 

and reactivated a number of of services by changing them to "automatic". One of
them must have done the trick because my PMail its working again now and I am happy.

I have a lot work to follow up on now that my mailer works again so I do not have the time
to test each and every service to find out which one it was but maybe this helps if
someone else has this problem again.

Thank you and sorry to anyone who spent time on this.

Regards,
Hanno

Hello

I have been running PMail for ages but only 4 days ago this problem came up for the 
first time. Whenever I try to send an email with an attachment making it a little 
larger it stops sending after a few percent, then times out and I get the error 
message below. 

I am running PMail Ver. 4.41 but am reluctant to upgrade before this issue is solved.
I have WinXP.
I have not recently changed hardware.
I have not changed MPU settings (but only after the problem has come up I tried and 
changed MPU settings to 1492, without success).
I have checked NVIDIA Network Controler and Checksum Offload was and is "disabled".
I have disabled the firewall for testing the issue, without success.
Changing the time-out within Pegasus only slightly changes the moment at which the 
issue occurs, but same thing happens.
I have installed and tested Eudora, and it works with the same accounts and settings.
I have checked this forum and found no further hints, so every help is appreciated. 

Thank you in advance for your kind assistance,
Hanno

Sometimes the error message also ends with
