I have a something in mailtransports but I can't see how to view it.

In wallet manager I see Filem Settingsm and Help, but no open button.

Advice please

You're using the Wallet Manager to view the data stored in the wallets correct?
If so, does the "mailtransport" item have an arrow beside it? Clicking this should reveal a series of additional items.

The problem in this case could be that Akonadi uses a format unique to it to store the data within KWallet (as it needs to attach data other than just the password). This means that the data is not readable by outside applications unfortunately though if it is the case.

Can you post a screenshot so I can confirm whether this is the case please?
