A followup ... OK the problem came back big time, within 2-3 hours of starting kmail around 6 accounts would be locked out.
In desperation I purged kmail, wiped all its accounts, re-installed & setup, reinstalled lots of apps in kmails dependency tree - same problem ! So in desperation I contacted my hosting company - 'err yep we have a problem - you are hosted in hong kong & we have cable damage, would you like to be hosted in the US ?' Moved to the US & all is well now :) Thought the followup may be useful - incidentally thunderbird did not suffer from this problem - must be an internal timing thing. Or maybe kmail just never times out and retries an account ? Anyhow thanks for your help Dave s -- kmail 'goes to sleep' https://launchpad.net/bugs/73639 -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
