Thanks Scott,
I have tried a few initial tests using two clients (NS and Outlook) and
Imail server using a header field of approx. 200 bytes (that field is in
addition to the standard headers). It didn't seems to choke on either the
clients or the server. I plan to do more extensive testing on larger
fields, but for now it seems that for my purposes, it will work.
Thank you for your help,
Chris Terrebonne

>The RFC isn't too clear on this, in my opinion. RFC821 says that a "text
line" can have a maximum length of 1000 characters. But, unlike 99.9% of
RFCs, it doesn't specify what a text line is. I would assume that means
the DATA section of a SMTP transfer, which would include headers. RFC822
doesn't seem to specify any maximum header lengths.
