unfolding header lines in TIdAttachment[File]

[Boba TC]

Thanks for you prompt reply, Remy.

... FoldLines is used when sending.

then it just does not do what it should.

the receiving server wants the attachment header lines to be unfolded

Why?  That is not standard practice for SMTP.

I am not sure about "standard practice for SMTP"; the RFC does allow it.

and header fields to be separated by "; " (semicolon followed by a space).

It is not possible to have multiple *headers* in a single line, that is not even legal to do, per RFCs.  By *fields*, are you thinking of *per-header attributes*, and not multiple *headers*?  Individual *attributes* can be on a single line, separated by "; ".  Indy already handles exactly that, if you use the TIdHeaderList.Params[] property to assign the attribute values.

I mean each header (single parameter) on a single line, like:

Code:

Content-Type: text/plain; charset="US-ASCII"; name="filename.txt"

instead of

Code:

Content-Type: text/plain;
       charset="US-ASCII";
       name="filename.txt"

I think they are called Values; so how do I ask Indy to put all values of every Name on a single line?
Also, compiler complains: " E3216 'Params' is not a member of TIdHeaderList"; do I need to update the Indy package? header files say "rev. 20.00" - 10 years old; is it too old?

One more thing... Will I be able to build the latest version of Indy Sockets/Protocols with BDS 12.0?
