That's a relief, to a certain degree, as that's one version of Visual Studio
I'm not using - I compile for VC7.1, VC8, VC9 and VC10 but not VC11.

I'm not aware of any IMAP specific issues - maybe someone else on the list
can step in if they are aware of any underlying connection timeout / out of
memory issues.

Is it reliably the same size when you see the problem and what sizes are you
having issues with?

Sorry but I got a little confused... You mentioned it was a timeout but then
mention an out of memory issue. Are these two separate issues? Also when you
say timeout, what do you mean?

For example: The connection stays alive but your callback doesn't get called
after receiving some data and the curl_easy_perform() doesn't return.

Are you able to reproduce the problem with a imap connection as opposed to a
imaps connection?

Additionally have you tried the curl command line utility to see if the same
thing happens with that?

Kind Regards

Steve
