zstyle -e ':completion:*:(ssh|scp):*' hosts \
    'reply=( ${${words[CURRENT]%.*}#*@}.{domain1,domain2,domain3,...} )'

This will complete the domains directly (with a leading dot) if you
have't already typed the host part.  A conditional test on
$words[CURRENT] could be added to set reply only if there is already
at least one dot.  Additional complexity is of course possible.  You
might also want to put the list of domain names in a variable where
it's more easily edited:

host_domains=( domain1 domain2 domain3 ... )

zstyle -e ':completion:*:(ssh|scp):*' hosts \
    '[[ $words[CURRENT] = *.* ]] && 
     reply=( ${${words[CURRENT]%.*}#*@}.${^host_domains} )'

If you're starting to get really complex conditions, I suggest putting
them into a function and replacing the string value of the style with
a call to the function.
