Question / Problem
When I tried to send an email to an catch-all mailbox which will be collected by smartpop2exchange some BCC recipients don 't get the mail. Why?
Answer / Solution
Please first have a look at FAQ in the help of SmartPOP2Exchange.
In case of using BCC there is definitely a loss of mails for server with the upper described behavior. BCC recipients are not stored in the header of a mail (that’s the sense of BCC).
So no software is able to replicate mails for BCC recipients.
You see, this is no bug. It’s simply impossible if the pop3 server has this wrong behaviour.
In general we do not recommend to use catch-all accounts because of this issue.
