Here's the code that check if specified email address is present in MailAddress collection:

if (ContainsEmail(email.To, "pat@example.com"))
{
    // ...
}

private static bool ContainsEmail(IEnumerable<MailAddress> list, string email)
{
    foreach (MailAddress address in list)
    {
        if (address.GetMailboxes().ConvertAll(x => x.Address).Contains(email))
            return true;
    }
    return false;
}

// Linq version:
private static bool ContainsEmail(IEnumerable<MailAddress> list, string email)
{
    return list.Any(address => address.GetMailboxes().ConvertAll(
        x => x.Address).Contains(email));
}
