Hi,

Thanks for the quick fix for the CRLF issue, that works now.
BTW, the example program still can't send the e-mail, because the dot stuffing doesn't work.

Here's the wireshark output from the session:
DATA
354 End data with <CR><LF>.<CR><LF>

Subject: SMTP example message

.The body of the message starts here.

.
It could be a lot of lines, could be MIME encoded, whatever.
Check RFC5322.
.

Could you please fix that too?

Thanks,

** [bugs:#1456] Curl SMTP client CRLF and dot stuffing doesn't work**
**Status:** closed-fixed

Hi,
I'm trying to send a simple e-mail with curl. SMTP has two caveats here: dot stuffing and CRLF, I've tried to test these in my sample e-mail.
This is the code, which is mostly the smtp example from curl source:
http://pastebin.com/0JtwGTqx
For the options, I've just added curl_easy_setopt(curl, CURLOPT_CRLF, 1L); to do CRLF conversions, and replaced \r\n in payload_text to see whether it works or not.
Bug #1: this example sends LF line endings on the wire, so my SMTP server refuses the e-mail. Shouldn't CURLOPT_CRLF convert them to CRLF?
Bug #2: dot stuffing doesn't happen. The lines with a dot in the first character aren't get prepended with an extra dot, so the transaction here fails (because of the lone LF.LF). If think an SMTP client should do this and not let the client take care of it.
Could you please investigate these?
Thanks,
