Solved 3CX SMTP Question

[jcostlow]

Hi Everyone,

We have a user who can't receive the welcome email from the PBX using 3CX SMTP.

I made the user account in AD, made the Exchange mailbox, synced ProofPoint users with the local AD and waited 15 a bit to send the welcome email. I know that for false spam ratings the SMTP will not resend for a while after failing.

My guess is I didn't wait long enough for proofpoint to replicate the new user across all their servers. It has since been 2 or 3 days and it won't send the welcome email. How long is the waiting period for it to try again?

@jcostlow did you setup the extension and define the email before you actually create the email at your Mail Server ? If so, then yes this will be bounced as the PBX tries to send email out to an email that didn't exist that moment.
Open a support ticket and we can check if this specific email is bounced.

Hi @NikosT_3CX I made the email address and synced it with the spam filter before creating the extension but the spam filter may not have fully propagated the email address causing it to deny the message.
