Question:
(We are using ChilkatMail2.dll.)
We have an end client trying to send emails/text messages and receiving error:
553-Relaying denied.
We are assuming that their STMP server should have Relaying turned on. Is this a correct assumption?
Is there a way around this? Some STMP server providers don’t want to turn this feature on.
Answer:
Usually the solution is to authenticate by setting the mailman.SmtpUsername and mailman.SmtpPassword properties prior to calling SendEmail. Many SMTP servers will allow non-relayed email to be sent w/out authentication, but require authentication when sending to external domains.
