Cutting out the rest of the data- This is where the connection is being 
closed:

278 45.011168   148.244.85.213        148.244.85.212        TCP      
smtp > 1342 [FIN, ACK] Seq=88 Ack=1 Win=62780 Len=0

The initial FIN is being sent by the SMTP server. Maybe there's a client 
IP address restriction in the MTA on 85.213 that didn't get changed?
