Subject: [exim] SAN, email notification and 'SMTP protocol synchronization error'...

I'm setting up my first SAN (an HP MSA 1040, indeed); setting up email i've
seen that does not work.

Digging a bit, i've found:

2016-06-15 18:26:26 SMTP protocol synchronization error (input sent without waiting for greeting): rejected connection from H=[10.5.254.2] input="NOOP\r\n"

digging a bit more:

there's some way to fix that (exim side)? Thanks.
