Hi,
I am following the sample code at
https://curl.haxx.se/libcurl/c/smtp-ssl.html to try to send an email
from a C program that I am writing, but it is not working. I am using
the same curl calls to do other stuff in the same program (HTTP POST,
etc.) and they work just fine. Here is the DEBUG info:
* STATE: INIT => CONNECT handle 0x8006bcc0; line 1402 (connection #-5000)
* Rebuilt URL to: smtp://smtp.gmail.com:465/
* Added connection 0. The cache now contains 1 members
[New Thread 7524.0x3cb4]
* Trying 74.125.25.109...
* STATE: CONNECT => WAITCONNECT handle 0x8006bcc0; line 1455 (connection #0)
* Connected to smtp.gmail.com (74.125.25.109) port 465 (#0)
* STATE: WAITCONNECT => SENDPROTOCONNECT handle 0x8006bcc0; line 1562
(connection #0)
* SMTP 0x8005cd88 state change from STOP to SERVERGREET
* STATE: SENDPROTOCONNECT => PROTOCONNECT handle 0x8006bcc0; line 1576
(connection #0)
* response reading failed
* multi_done
* Closing connection 0
* The cache now contains 0 members
curl_easy_perform() failed: Failure when receiving data from the peer
My source code is below.
Any advise?
Thanks everyone!
