Topic: Outlook clients can't send anymore

Hi!
I have been using iRedMail for quite a while with no problems but
for the past few days my outlook users can no longer send emails
I did not touch anything on the configs so I am wondering why
this problem occured.

From the logs this things show up

May 24 22:11:26 pen3 postfix/smtpd[20649]: connect from unknown[10.75.0.222]
May 24 22:11:26 pen3 postfix/smtpd[20649]: CDC9D2AA038D: client=unknown[10.75.0.222], sasl_method=LOGIN, sasl_username=xxxxx@xxxxx.xxxx
May 24 22:12:41 pen3 postfix/smtpd[20649]: lost connection after DATA (0 bytes) from unknown[10.75.0.222]
May 24 22:12:41 pen3 postfix/smtpd[20649]: disconnect from unknown[10.75.0.222]

Pls. Help ...
Thanks

Anything change during these days?
Server configurations, client software, network switches, etc?
