The exim ldap lookup returns a comma-separated list of values for each
attribute returned. For consistency this is so even for an attribute
having only one value. Exim's standard list-parsing facilities handle
list items which contain the list separator by doubling any such.
The change was made so that it was possible to unambiguously parse
these; it was previously not.
An alternative to the "sg" above for extracting the list value would
be to use (from 4.83 onwards) ${listextract {1}{the_complete_list}}.
For either "sg" or "listextract" you might prefer the style
${lookup ldap {ldap://.....} {modifiy $value here} }
