Yah, thanks!

I see HTTP can detect the OS but seems IMAP is new. So there is no way actually....

Not in any reliable way.

Actually, there is an IMAP proxy (running dovecot) between the real mailserver and mobile device.

I wonder if p0f would help at all, guess it depends what kind/if any proxy exists between the mobile device and the server

I use the Messaging application on mobile device (which use to check sms also).

What I want is open port 143/993 for checking email via IMAP but only allow mobile device to check it. User can configure on their Outlook/Thunderbird... to check mail also but I want to deny this case.

Does the 'mobile device' have an application that supports imap/pop3 ?, or are you talking about to access via webmail ? 2009/10/16 Thu NGUYEN ntathu@tma.com.vn:

Hello,

Do you have any way to detect the client which is connecting to our IMAP server?

I actually have an mail server which use dovecot but I just want to allow mobile device access to this server to get email, not desktop as Outlook, Thunderbird ...

Thanks for your advice.
