That is correct. POP-before-SMTP is an antiquated and obsolete feature 
that only works with Sendmail. I'm even considering removing it 
altogether and will most likely do so soon. After all: Our default MTA 
has been Postfix for quite some time now.

POP-before-SMTP has always been a hack and it was introduced before 
proper SMTP-Authentication was supported in Sendmail. But for two 
decades SMTP-Auth has been and is a standard feature of MTAs.

Therefore: It's best to forget about POP-before-SMTP. Instead enable 
"Enable SMTP Auth" and have users login with their username and password 
in order to send email.
