I've just started using the Defer/Marking feature (1.59.3) and found a way to cause a loop. I had one of the boxes processing 30 emails per run. With Defer rules added, everytime it restarts the fetch the emails are deferred again, if there are more than the 30 defers it keeps going. I've removed the emails per run limit now. I've added a rule :- Delete From: = List deletefrom Is that correct? Ian -- Ian Hamilton (RISC PC RO4) http://www.hamiltoni.pwp.blueyonder.co.uk/ (Iyonix RO5) Programs compatible with RISC OS 3/4/5
