hello I try to send an email from arduino ethernet through an account smt2go and telnet but I do not know where is the problem because my receiver does not receive anything in spite of write the commands of telnet are well like you can see on the image attachment , the weirdest is the report in my smtp2go account records the shipping.
thanks.
