printf("Insert the subject:\n");
scanf("%s",sub);
strcat(sub,"\r\n");

    This is what the man page will tell you: `%s` format stops scanning at the first whitespace. I suggest using `fgets` and then the input will already be ended by a newline, you won't have to add one. – Weather Vane Jun 17 '18 at 12:29
  • Its true, now works perfectly ty! – Jose Manuel Jun 17 '18 at 12:40
  • I do not see how this question is related to anything around SMTP or even sockets at all. – alk Jun 17 '18 at 16:37
