SMTP and Ironport S160

[praveen.ghimire]

Hi,

We've got the following setup:

A Cisco AP

Ironport S160

Exchange 2010

iPhones

We've setup the iphones to bypass proxy when connected via the AP. The http and https traffic seems to go through fine but we can't get the SMTP traffic to go through or come in. I've setup the tracking in Exchange and can not see the email hitting the Exchange server.

We've tried with putting in the full proxy detail in the iPhone wireless setup but still the same result. 

Can someone advise

Thanx.

Hi Praveen,

As you know the WSA can inspect HTTP/HTTPS/FTP but email protocols are handle by C-Series.

Based on the apple link below the Exchange aplication will use port 993 to recieve emails and in order to send emails it needs ports 587, 465, or 25

http://support.apple.com/kb/ht1421

So this traffic shouldn't be getting to the WSA.

HTH
