Hello everyone,
I have to setup encrypted communication (force TLS) with a partner.
I created a new sendconnector with the following configuration:
AddressSpaces : {SMTP:testsender.CheckTLS.com;1, SMTP:CheckTLS.com;1}
AuthenticationCredential :
CloudServicesMailEnabled : False
Comment :
ConnectedDomains : {}
ConnectionInactivityTimeOut : 00:10:00
DNSRoutingEnabled : True
DomainSecureEnabled : False
Enabled : True
ErrorPolicies : Default
ForceHELO : False
Fqdn : MAILSERVER.FQDN
FrontendProxyEnabled : False
HomeMTA : Microsoft MTA
HomeMtaServerId : MAILSERVER
Identity : Checktls
IgnoreSTARTTLS : False
IsScopedConnector : False
IsSmtpConnector : True
MaxMessageSize : 35 MB (36,700,160 bytes)
Name : Checktls
Port : 25
ProtocolLoggingLevel : Verbose
RequireOorg : False
RequireTLS : True
SmartHostAuthMechanism : None
SmartHosts : {}
SmartHostsString :
SmtpMaxMessagesPerConnection : 20
SourceIPAddress : 0.0.0.0
SourceRoutingGroup : Exchange Routing Group (DWBGZMFD01QNBJR)
SourceTransportServers : {MAILSERVERS}
TlsAuthLevel : EncryptionOnly
TlsCertificateName :
TlsDomain :
UseExternalDNSServersEnabled : False
Im trying to send a mail to testsender.checktls.com but the mails are still stucking at the mail queue with the following error:
441 4.4.1 Error encountered while communicating with primary target IP address: “421 4.4.2 Connection dropped due to SocketError.” Attempted failover to alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failed to
all alternate hosts.
Do you have any ideas?
Many Thanks!
