Or tabulator or space:

$ echo -e "foo.example.com\t/home/joe" > mylist
$ echo -e "bar.example.com\t/home/jane" >> mylist
$ parallel --colsep '\t' echo "Server: {1} Path: {2}" < mylist
Server: foo.example.com Path: /home/joe
Server: bar.example.com Path: /home/jane

This might be what you really want:
$ parallel --colsep '\t' echo "ssh {1} ls {2}" < mylist
ssh foo.example.com ls /home/joe
ssh bar.example.com ls /home/jane

...without the echo

And BTW, this is the same:
parallel --colsep '\t' echo "ssh {1} ls {2}" :::: mylist
