Hi Steve, Thanks for your quick response to my problem on large attachments in Curl SMTP.
Your comment on passing the full string to the read callback identified my error: I misunderstood where chunking occurs in the upload process. I now chunk up to Curl max buffer size in the callback, and it works fine! Many thanks for your help. I don't often run up against brick walls, but this was one, and I value your insight. Regards, Mark. ------------------------------------------------------------------- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette: http://curl.haxx.se/mail/etiquette.html
