There's always a risk when getting error messages even if the risk might be small. Does the error keep repeating if you dismiss it? Have you tried switching the addon off then on again?

This is AccountSummary:Print() from the postmaster addon.

--[[ Outputs a verbose summary of all loot and currency ]]
function class.AccountSummary:Print()
    local tagSuffix = self.chat.tagSuffix
    if self.account then
        local mailIconSize = math.max(self.iconSize, 100)
        mailIconSize = string.format("%s%%", tostring(mailIconSize))
        local mailIconString = zo_iconFormatInheritColor(self.mailIcon, mailIconSize, mailIconSize)
        local account = mailIconString .. self.account
        if not self.chat.tagColor then
            account = self.prefix .. account .. self.suffix
        end
        self.chat:SetTagSuffix(account)
    end
    LibLootSummary.List.Print(self)
    self.chat:SetTagSuffix(tagSuffix)
end

It doesn't do anything maliculous it just adds a message to the chat saying what you got from your recently opened mail.
There is no risk to you or your account. The Account Summary in question is not your ESO account it's just a 'class' in the postmaster addon.
