Hi Toke,
It's true I'm using a different email as my from address to the full one 
in kolab as I migrated from an existing email of andrew@ wheras kolab by 
default is andrew.leech@
However sending as the full email doesn't work either, nor in roundcube 
(where it was already using the full one by default)

I also tried putting my andrew@ address in "Sender Access List" in 
kolab-webadmin / User / Configuration but that hasn't helped, nor in " 
Recipient(s) Access List". The labeling would suggest the sender access 
list is the correct place to put it, so maybe I've got a bug in my 
system somewhere.

I guess the security risk of me sending as anyone isn't that bad, at 
this stage I'm only hosting for myself. I run the risk of forgetting 
I've left this open though, which I'd rather not do. I'll keep 
investigating.

Thanks,
Andrew
