Hello, I've different setup of perdition proxy (POP3 and IMAP4) and I wish to have a kind of fallback server. I'm using popmap.re regexp filtering to loadbalance over 2 mailboxes server based on the name of the owner (a-l -> server a, n-z -> server b). Both server are able to serve all mailboxes so I wish to know if I can setup something like this : ^[a-l] : serverA:143,serverB:143 ^[n-z] : serverB:143,serverA:143 If serverA fail to answer then perdition uses serverB and vice-versa. Thanks -- Alexandre Ghisoli
