Firmware 9.408-4 has a Bug with Recipient Verification

what i see is 

in Definitions & Users/ Authentication Services/ Servers/ 

if i click on the test server settings, i get password wrong error, even though i know the password is correct, if i paste the password again new, i still get password error.

however if i go to the advanced tab and do a sync /prefetch it works.

also if i test the email , recipient verification still works as expected 

so it would like like being able to update the stored credential is whats wrong ?

this is exactly the probelm.
another Person has opened a Support case (Sophos). I have been following the case with great interest ;)

If i do the same as you, go to the advanced tab and do a sync /prefetch, it does not work.

I chose two users:
@ 1X User which is defined under Definitions & Users/ Authentication Services/ Authentication Server
@ 1x User for which i will send to a E-Mail recipient, in other words, my Active Directory Users which have a E-Mailadress.

The test was, i had send a Mail from my Business E-Mail to my private E-Mail (Active Directory User on my Server) with enabled recipient verification under SMTP/ Routing/ Recipient Verfication/ verfiy recipients with Active Directory And: received the following error:
