C2Tray Email forwarding: Error

Not sure where to post this, so posting it here.

Email forwarding has been working fine. I haven’t changed any settings, but today the following error is occurring:

“Email not sent: dataend at C2stray201.pl line 2478”. Any ideas what could be the cause and/or fix for this?

Please send me you c2tslog.txt file (usually in the C: folder). And tell me the time of day this error occurred (and your time zone). Thanks.
