As I suspected:
* Your old server supported "insecure" ("plain text") SMTP AUTH methods
  (LOGIN and PLAIN) even over unecrypted SMTP connections 
  [it is not the recomended way].
* Your new SMTP server supports LOGIN and PLAIN "SMTP AUTH" only over
  encrypted connections as indicated in reply to second EHLO in my test.
  [ BTW *DO* change your SMTP password ]

 My test on the new server:
 >>> EHLO ......
 <<< 250-mta1.es.aau.dk Hello ......
 <<< 250-SIZE 52428800
 <<< 250-PIPELINING
 <<< 250-STARTTLS
 <<< 250 HELP
 >>> STARTTLS
 <<< 220 TLS go ahead
 >>> EHLO ......
 <<< 250-mta1.es.aau.dk Hello ......
 <<< 250-SIZE 52428800
 <<< 250-PIPELINING
 <<< 250-AUTH PLAIN LOGIN
 <<< 250 HELP

So: Your problem (IMHO) is how to *force* gnus to use STARTTLS 
(encrypted connection) in SMTP session to give it a chance to use
SMTP AUTH (that has worked).
