Email logger does not support multiple TO email addresses

Presently the TO address supports only a single target email address. However this field is multi-valued in the sendmail API and the logger could easily be extended to support this. There is no tooltip on this field so it was not intuitive that this restriction applied - however attempts using "," and ";" delimiters both failed. Work-arounds include setting up multiple loggers, or using a distribution list. However there are times when this would still be handy - especially when d-lists are not easily modified or the requirement is only temproary.
