if lets say someone sends me an email to an individual account created on the SBS console 'email@example.com' it will come through
however if they send an email to 'firstname.lastname@example.org' would it arrive from an external source?
I ask this because someone early today sent an email from an external source from mailchimp to allusers in our business which is a group off all email address's and it came back with a hard bounce back which according to mailchimp indicates one of the following:
A hard bounce indicates a permanent reason an email cannot be delivered. Hard bounced email addresses are removed automatically and immediately from the active subscribers and placed in the Cleaned portion of your list. Cleaned subscribers will be excluded from future campaign sends to this list. While there are many reasons an email address may hard bounce, below are some common reasons this could happen.
•Recipient email address does not exist.
•Domain name does not exist.
•Recipient email server has completely blocked delivery.
now I have checked that the email address is correct (which it is) and I also checked the domain was typed in correctly. which it was!
let me know your thoughts,
