I have the same issue and still no solution:
IMAP Error: Authentication for <user> failed (LOGIN): "a001 NO LOGIN failed" in on line 0
IMAP Error: Authentication for <user@domain.tld> failed (LOGIN): "a001 NO LOGIN failed" in on line 0
When i try this, posted from hcl:
[step 2] from hcl
$telnet localhost 143
#this sample on mybox
telnet localhost 143
Trying 127.0.0.1...
Connected to localhost (127.0.0.1).

when i try to send mails via telnet localhost 25 they are sent and received and everything works fine
Is there no solution, is this maybe even a bug ?
