Hello,
I have a alias "XXXX@XXX.com" forward to email "YYY@YYY.com"

On delivery log I have found this:
[2017.12.06] 09:55:04 [01136] Delivery started for [fromEmail] at 09:55:04

[2017.12.06] 09:55:09 [01136] Delivery for   to <YYY@YYY.com> has completed (Bounced)

 

The FROM address is empty and email is Bounced!

I test with a "normal" user on CC and I received correctly.

 

This is a big problem for me, can you help me to resolve this issue?

 

I have SmarterMail 16.3.6544
