...to respond to my own thread starter and to your posting Hansker.
I changed everything around and no longer have 'stuck spam' queues and all that stuff. Adopt whatever you like of the following Hansker, it is just a precis of my changes, perhaps you too will find things resolved to your own satisfaction as well:-)
* Topmost of all - move to SME Server 6.0.1-01
* Purchased Dungog's TDMA email solution, only to find a week later he deprecated it (still available but not supported). So, after the rebuild (clean install of SME Server 6.0.1-01), I have not (re)installed it. Maybe I'll have another go with the other email stuff that came with the purchase if any further email trouble arises.
* Ditched spamassassin and so, without all the previous stuff, I have no stuck queues... which now do not require messing about with qmHandle etc.
* adopted the YUM-installed Amarvis-NG anti-virus stuff from Page Fault - most recommended, automagically it updates some SME Server files too particularly in the console manager area.
* adopted Ray Mitchell's totally wonderful recent smtpfront-qmail patch (in conjunction with the old mailfrontrules rpm) - it's sooooo good it should obligatory:-)
There may be other things done I've forgotten about but the above should ameliorate your situation somewhat...(?)
best wishes, Robert
