I enabled the SMTP logging in Exchange Transport in ESM and am getting these 
two errors all the time in the Application Log. 
 
This is an SMTP protocol error log for virtual server ID 1, connection #688. 
The remote host "67.69.144.11", responded to the SMTP command "xexch50" with 
"504 Need to authenticate first  ". The full command sent was "XEXCH50 1028 2  
".  This will probably cause the connection to fail. 
 
This is an SMTP protocol error log for virtual server ID 1, connection #687. 
The remote host "165.212.65.113", responded to the SMTP command "rcpt" with 
"551 <izzie@xxxxxxxxxxxxxx <mailto:izzie@xxxxxxxxxxxxxx> >... User not local  
". The full command sent was "RCPT TO:<izzie@xxxxxxxxxxxxxx 
<mailto:izzie@xxxxxxxxxxxxxx> >  ".  This will probably cause the connection to 
fail.
 
I am wondering if I should be worrying about this or if it will go away with 
time? Thanks
 
Regards,
Andrew
