The *22 RFCs allow it, so Postfix does too.
Comments starting line 59 of src/global/is_header.c:

The Postfix MIME parser also strips the obsolete whitespace:
Comments starting line 866 of src/global/mime_state.c:
* Normalize obsolete "name space colon" syntax to "name colon".
* Things would be too confusing otherwise.
If MIME processing is disabled by the administrator, the above applies
only to the primary headers.
*Each* folded header-line may be up to 100k bytes in length. There is
no limit on the total length of all headers, other than the message
size limit.
