Hello, The last version of Mail support S/MIME certificates. I have several accounts on my iBook and I tried with a Thawte certificate for my main mail account. So far so good. Then I tried another certificate (from another provider to avoid cinfusion) for my .mac account.. and despite the fact the second certificate is stored (like the first one) in the KeyChain, Mail doesn't show the little icons for my second account. Is Mail able to handle S/MIME certificates only for one of the accounts ? Thanks in advance
