>Why not verify recipient with callout? Actually, this is a bit more complex than previously stated. The mailbox also resides on our filtering plateform : when an incoming message turns up, a copy of it is stored locally, and another one sent to the remote server. If this latter one is down, our customers can come and check their incoming emails on our platform using a webmail interface. So far, when a mailbox is created on the remote server, the 'remote' administrator also has to declare the newly created email address on our filtering platform (this action performs the local mailbox creation). If not, we consider the email address non-existant. >From now on, I'd like this creation to be made automatically so the 'remote' administrator should not have to worry about the declaration on our plateform. That's why running a script at the ACL level would have done the trick : if the recipient adress is unknown, verify it and if it succeeds, create the local mailbox and deliver both copies of the message. But callout may also do the trick. If the verification succeeds, I can set a $acl_ expansion variable, which would trigger a router, before the ones that deliver both local and remote copies, that creates the mailbox and do somme other stuff. Does that sound good to you ? -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
