I have built a custom recipient source that fetched mail-recipients from our own external database and it works perfectly by implementing the EPiServer.Mail.Core.Sources.IRecipientSource inferface. I have one problem though. How do I catch the bounced emailadresses coming back from EPiServers mailcluster via the EPiServerMailService.asmx webservice. My guess was that it is done by implementing the logic in the method AddBouncedAddress in the custom recipient source. I tried that but it is not executed. When is the AddBouncedAddress-method called? What do I use it for? Is it possible to catch the incoming bounced addresses at all?
So it's not possible to get the bounce from my customSource without making a http-listener?
