Hi, I use a content filter that does not accept DSN.
=> Postfix 25 => FILTER (via content_filter) 10025 => Postfix 10026 => Is it possible to "remove" the notify=SUCCESS tag in the first postfix and re-insert it in the second one ? I tried to do it with a virtual_maps/pcre couple but it seems it only scans/rewrites the "<a...@b>" pattern in the "rcpt to" field. As if the notify=SUCCESS tag was not seen. Not very surprised but I hoped to have a solution. Thank you Alain
