It looks as though I'm running 5.3.6 according to vdeldomain -v, which would appear later than 4.9.2, but... still doesn't work right, and I have an alias sitting around now doing nothing but shoving 100 spam messages a day into my inbox (Haven't figured out DSPAM for vpopmail or qmail yet.)
Please try one of the 5.4 releases. I recall that there were some bugs fixed related to deleting alias domains.
I do know that the current releases will properly delete and alias domain without removing the real domain it points to.
