These SMTP codes always take place in pairs, which means that both of the servers will transmit SMTP codes, until either the conversation is successful, or fails.When troubleshooting dropped or failed SMTP conversations, there are two main types of codes used; 400 and 500 error codes. The first number in https://community.mimecast.com/docs/DOC-1369-mimecast-smtp-error-codes this code, generally indicates whether the MTA accepted the command or if the command was rejected. If you are trying to send an email to a Mimecast customer and receiving any of the error codes below, this should be escalated to the Mimecast Administrator of the intended recipient. Mimecast is only able to deal with the designated contacts for our customers.The values of interest for this article are:4xx: The server has encountered a temporary failure.

Quote Postby Stitch » 2010-07-16 14:16 Hello everyone,This is my first time installing/using hMailServer and everything seems to be working OK so far. My Set-up:Windows 2008 x64IIS 7PHP 5.3.2MySQL 5.1.48hMailServer 5.3.2-B1769SquirrelMail 1.4.20The system receives mail perfectly, however when sending mail I seem to have a very 451 internal error strange problem. I have searched and read many 'almost' related posts and topics but nothing seems to match my issue. The torubleshooting guides state that the SMTP message I am receiving may be related to Greylisting, however every domain on my server has greylisting turned off. MX records resolve fine and the daignostics tool shows no errors.When sending email out (using either SquirrelMail or simply connecting to localhost using SMTP) I receive the following (copied from the logs):"SMTPD" 2088 659 "2010-07-16 11:59:09.749" "127.0.0.1" "SENT: 220 Hi There""SMTPD" 2084 659 "2010-07-16 11:59:09.765" "127.0.0.1" "RECEIVED: EHLO http://www.mydomain.net""SMTPD" 2084 659 "2010-07-16 11:59:09.765" "127.0.0.1" "SENT: 250-mail.mydomain.net[nl]250-SIZE 20480000[nl]250 AUTH LOGIN PLAIN""SMTPD" 2084 659 "2010-07-16 11:59:09.765" "127.0.0.1" "RECEIVED: MAIL FROM:
