Hi
Recently our mail server migrated from exchange 2007 to exchange 2013 on prem and Vfire application send mail without any issue using exchange 2007, but when we change host to exchange 2013 I am getting below error
Infra.Mail.Smtp.SmtpSendMailHandler - smprod02 - Outgoing VMware Mail - ERROR: (Infra.Mail) Error in Infra.Mail Infra.Mail.Smtp.SmtpSendMailHandler - smprod02 - Outgoing VMware Mail - Type: (System.RuntimeType) Infra.Mail.InfraMailServerException Infra.Mail.Smtp.SmtpSendMailHandler - smprod02 - Outgoing VMware Mail - Source: (Nothing) Infra.Mail.Smtp.SmtpSendMailHandler - smprod02 - Outgoing VMware Mail - Message: (System.String) "There was an error communicating with the mail server. Please check your authentication methods, user ID, password and SSL settings. Consult the event log for more information. Email Subject was: vFire Call : 2754064 : Forwarded" Infra.Mail.Smtp.SmtpSendMailHandler - smprod02 - Outgoing VMware Mail - Stack Trace: (Nothing) Infra.Mail.Smtp.SmtpSendMailHandler - smprod02 - Outgoing VMware Mail - InnerExceptionType: (System.String) "MailBee.SmtpMail.MailBeeSmtpRefusedDataException" Infra.Mail.Smtp.SmtpSendMailHandler - smprod02 - Outgoing VMware Mail - InnerExceptionMessage: (System.String) "The mail message data has been rejected by the server. The server responded: 550 5.7.1 Client does not have permissions to send as this sender."
Although Exchange 2013 server receive connector are set with appropriate extended AD rights. Anyone know how to resolve this issue.
