Exchange 2013 send connector after provider switch started sending on behalf of.

Exchange 2013 send connector after provider switch started sending on behalf of.

We have a on premises exchange 2013 server.

we receive through a pop3 into the server via 3rd party software which is working fine.
then when we send out we have a send connector with the providers smtp details ( say as send account)

our previous provider we sent email from through the send connector and it was received by recipient from the sender  ""

we changed our provider - all settings are the same in the smtp bar the new password but now the email is received as from " on behalf of"

I have no idea why the change of smtp provider would cause this as surely this is  controlled in Exchange

any help much appreciated

This sounds like it's been applied by your provider opposed to your Exchange Server.  I would raise it with them.

I'd also consider getting rid of the POP Service and use an MX Host (Direct SMTP to your server).   If security is a concern I would look at a third party email filtering service which will cover your inbound and outbound mail.

Thank you for your help

indeed this was a shared hosting supplier issue, if mail was sent out from exchange on the generic connector email details, if they didn't match the actual email address of the person that was sending an email, it would put in in the "on behalf of" to ensure the recipient knew the actual sending email (the connector one)

I got round this buy buying a small VPS with cpanel and using that as a relay server which didn't have that feature, and using that VPS' ip as the sending server in the Exchange send connector
