[MlMt] Trouble connecting to iCloud (certificate validation)

[Scott A. McIntyre]

Hi,

<aluminium_hat>

For the past few months, every now and again when MailMate tries to talk 
to Apple's iCloud email infrastructure, a certificate validation error 
occurs.

The certificate that MailMate reports is a wildcard for *.mail.me.com, 
signed by Symantec ("Symantec Class 3 Secure Server CA - G4"), with a 
serial number of 11 04 0c 72 fb d3 37 73 1f f4 f0 dc b3 c0 e7 17.

The error in MailMate/OS X is "This certificate was signed by an unknown 
authority".

In my Keychain Manager I have a "Symantec Class 3 Public Primary 
Certification Authority - G4" -- not quite the identical name, but, I'm 
grabbing this from the pop-up that appears when MailMate connects, and 
signing versus issuing may account for a slight discrepancy.

Decades of doing what I do for my day-job has me just paranoid enough to 
raise an eyebrow on this one.

Has anyone else encountered this?

Thanks,

Scott
