>From my reading of RFC2821, 

     <'list at icpsr.umich.edu'>

is invalid.  Here is how I parse it, followed by the RFC 2821

To: "list at icpsr.umich.edu" <'list at icpsr.umich.edu'>
To: [display-name]         angle-addr
To: [display-name]         "<" addr-spec ">"
To: [display-name]         "<" local-part "@" domain ">"

to              =       "To:" address-list CRLF
address-list    =       (address *("," address)) / obs-addr-list
address         =       mailbox / group
mailbox         =       name-addr / addr-spec
name-addr       =       [display-name] angle-addr
display-name    =       phrase
angle-addr      =       [CFWS] "<" addr-spec ">" [CFWS] / obs-angle-addr
addr-spec       =       local-part "@" domain
local-part      =       dot-atom / quoted-string / obs-local-part
obs-addr-list   =       1*([address] [CFWS] "," [CFWS]) [address]
obs-angle-addr  =       [CFWS] "<" [obs-route] addr-spec ">" [CFWS]

Note that 


does not have apostrophes at each end.
