Hi All
I've configured my smtp proxy to work with email encryption just fine (as per document https://community.sophos.com/products/unified-threat-management/astaroorg/f/56/t/49267).
However, I have just noticed the following: I had by mistake set on my cpanel the following option: Send all unrouted email for: (attached)
When I decided to change this to "Discard with error to sender (at SMTP time)" every email I am sending out an email from my domain I am getting an automatic reply back
SMTP error from remote mail server after RCPT TO::
host ****.gr [*******]: 550-Verification failed for
550-No such person at this address
550 Sender verify failed
prvs=0494c85d84=*****@***.gr doesn't exist as a user
Anyone seen this issue before?
Thanks
