So as to protect our mail servers from block lists and to protect potential spam or malware being relayed on, we have a number of checks that are applied to email being sent through smtp.aa.net.uk. These include:
 
*IPs not on our network will need to Authenticate using their mailbox credentials
*We'll block individual messages if they are bounces (mail delivery failure notifications) - we don't like to relay on bounce messages from customers own mail servers
*We'll block individual messages if they contain malware (virus)
*We'll block Authenticatedindividual usersmessages if theythe sendsender multipleaddress emailsis ininvalid a(eg shortno time period to invalidMX emailrecords addressesetc)
*We'll block Authenticated users or IPs if they try to send multiple emails in a short time period that have a highto highinvalid spamemail scoreaddresses
*We'll block Authenticated users or IPs if they try to send multiple emails in a short time period that have a high high spam score
*We'll block the email if the sender address is invalid (eg no MX records etc)
 
There are other check, but the ones above are the main ones.
