Kasper, FWIW, we don't allow our customers to forward email from their accounts -- no exceptions.
If a user with multiple accounts really wants to aggregate their email at B, we suggest they configure their account at B to fetch their email from A, or; alternatively, just use an email client that fetches mail from both accounts. Put differently, why should the ESP managing B have to gamble on the quality of anti-spam filtering on A? Suppose the destination email address at B is actually a Distribution List with a few thousand members? And suppose the distribution list members are on various email domains external to B? Why should B have to risk its reputation that way? Regards, Mark -- _________________________________________________________________ L.
