Currently I’m trying to send SMTP mail thru Codeunit 400. I have received a Hotfix (KB981354) from partnersource to change the default port 25 to 587 for smtp.gmail.com in the aforesaid codeunit.
I have done almost the same as written in the Article (KB Article Number(s): 981354).
Still I’m not able to send any emails due to the following error message :
“ The SMTP mail system returned the folloeing error message: The SMTP server requires a secure connection or the client was not Authenticated. The server response was:5.7.0 Must issue a STARTTLS command first. b11sm2417142rvf.10 “
I’m working in Window XP (SP3) machine which is itself my Native Database Server Machine. Navision Version is : Nav 2009 SP1 (IN).
What is the reason behind it ?? Kindly reply.
