Secondo un'indagine automatizzata di maggio su circa 800.000 server di posta, Exim detiene una quota del 59,59% (rispetto al 59,15% di un anno fa), Postfix \u00e8 utilizzato dal 33,64% (33,76%) dei server di posta, Sendmail - 3,55% (3,55%), MailEnable - 1,93% (2,02%), MDaemon - 0,45% (0,56%) e Microsoft Exchange - 0,23% (0,30%).     <\/p>\n<p>Principali modifiche:  <\/p>\n<ul>\n<li class=\"l\"> \u00c8 stata implementata una nuova condizione 'seen' in ACL, che pu\u00f2 essere utilizzata per controllare eventi precedenti relativi agli utenti e agli host. La nuova condizione semplifica il lavoro con le liste grigie, ad esempio, per creare una semplice lista grigia per consentire un nuovo tentativo di connessione si pu\u00f2 utilizzare ACL 'seen = -5m \/ key=${sender_host_address}_$local_part@$domain'.\n<li class=\"l\"> \u00c8 stata aggiunta 'mask_n', una variante dell'operatore 'mask', che manipola gli indirizzi IPv6 normalizzati (con e senza due punti).\n<li class=\"l\"> Nelle utility exim_dumpdb e exim_fixdb \u00e8 stata aggiunta l'opzione '-z' per restituire il tempo senza considerare il fuso orario (UTC);\n<li class=\"l\"> In un processo in background \u00e8 stato implementato un evento che viene emesso in caso di errore di connessione TLS.\n<li class=\"l\"> Nel modo di debug di ACL ('control = debug') sono state aggiunte le opzioni 'stop', 'pretrigger' e 'trigger' per gestire l'output nel log di debug.\n<li class=\"l\"> \u00c8 stata aggiunta una verifica per l'escaping dei caratteri speciali nelle query di lookup, se nella stringa di richiesta vengono utilizzati dati provenienti dall'esterno ('tainted'). Se i caratteri non sono stati escapati, l'informazione sul problema viene attualmente registrata nel log, ma nelle versioni future porter\u00e0 a un errore.\n<li class=\"l\"> \u00c8 stata rimossa l'opzione 'allow_insecure_tainted_data', che permetteva di disattivare l'output di errore per l'escaping non sicuro dei caratteri speciali nei dati. Inoltre, \u00e8 stata interrotta la supporto per log_selector 'taint', che consentiva di disattivare l'output nei log degli avvisi riguardanti problemi di escaping.      <\/ul>\n<p>Fonte: <a
