Im trying to send to an email from a clients place who is on a different ISP to an address on our mail server from a type of webform
its pretty simple
it sends an alarm to me via email
the smtp server its coming from over here is "smtp.vodafone.co.nz"
however I get in my outlook folder a "Mail Delivery System" failure notice
Diagnostic-Code: smtp; 5.1.0 Unknown address error 553-'5.7.1 <example@mycompany>: Sender address rejected: not logged in (delivery attempts: 0)
it actually has a copy of the info that is sent by the form too (so Im sort of getting the message )
Im presuming that a lot of mail may not be getting to me because of this ?
