It provides a custom Dovecot filter with a failregex, a jail configuration for POP3/IMAP ports, log path, retry limit, and optional timing values, followed by restarting fail2ban. ### Source excerpt Domyślna konfiguracja fail2ban'a (na Debianie) nie zawiera reguł pozwalających na blokowanie prób włamań na skrzynki POP/IMAP dla dovecota (no chyba że korzystamy z saslauthd). Można szybko utworzyć własny zestaw filtrów co przedstawię poniżej. Tworzymy plik: /etc/fail2ban/filter.d/dovecot.conf [Definition] failregex = (?: pop3-login|imap-login): .*(?:Authentication failure|Aborted login \(auth failed|Aborted login \(tried to use disabled|Disconnected \(auth failed|Aborted login \(\d+ authentication attempts).*rip=(?P\S*),.* ignoreregex = Później dopisujemy na końcu pliku: /etc/fail2ban/jail.conf [dovecot] enabled = true filter = dovecot port = pop3,pop3s,imap,imaps logpath = /var/log/mail.log maxretry = 20 # te dwa poniżej wedle uznania - ja mam dobrze ustawione default'y #findtime = 1200 #bantime = 1200 Zostało zrestartować fail2ban'a: ## pflogsumm - Mail Statistics for Postfix DevFeed: [pflogsumm - Mail Statistics for Postfix]() Original publisher: [Read original article]() Author: Tom Published: 2011-09-22T00:00:00Z Content type: tutorial Language: en Sources: [Tomasz Gągor]() Topics: [monitor](), [Server]() Tags: [command](), [generate](), [health](), [how-to](), [installation](), [linux](), [linux-mail-tools](), [logs](), [mail](), [mail-server-management](), [monitor](), [pflogsumm](), [postfix](), [postfix-log-analysis](), [postfix-mail-statistics](), [postfix-monitoring](), [process](), [reporting](), [review](), [run](), [server](), [standard](), [statistics](), [volume]() ### AI overview A tutorial on using pflogsumm with Postfix logs to generate mail statistics for reviewing a mail server's health, traffic, and communication issues.

To co znalazłem wygląda tak: (echo "testowa wiadomosc"; uuencode test.zip test.zip) \ | mail -s "Test" testowy@mail.pl Wiedząc już jak wysyłać maile z załącznikami, mały mail bombing mogłem zrobić tak: for i in `seq 1 100`; do (cat tekst.txt; uuencode test.zip test.zip) \ | mail -s "Test $i" testowy@mail.pl; done ## Dynamiczne IP i RBL'e DevFeed: [Dynamiczne IP i RBL'e]() Original publisher: [Read original article]() Author: Tom Published: 2011-08-27T00:00:00Z Content type: tutorial Language: pl Sources: [Tomasz Gągor]() Topics: [DHCP](), [Development]() Tags: [dev](), [dhcp](), [linux](), [mail]() ### AI overview A guide to monitoring a mail server's dynamic IP against real-time blocklists (RBLs). It uses the rblcheck tool and a scheduled shell script to identify blacklist listings within an hour while avoiding unnecessary notifications when the IP is clean. ### Source excerpt Mój serwer pocztowy działa od jakiegoś czasu na dynamicznym IP (dobre bo tanie...) i przeważnie nie ma z tym problemów. Postarałem się jak mogłem ustawiając SPF'a i DomainKeys aby uwiarygodnić go u większych dostawców poczty. Niestety wszystko to diabli biorą w momencie gdy wygasa mi leasse DHCP i dostaję nowe IP po jakimś spamerze/zombiaku. Wisi takie w 2-3 większych RBL'ach i o dostarczaniu poczty można zapomnieć. Miło gdy jeszcze zdalny MTA zechce odesłać zwrotkę "zróbta coś bo wisisz w RBL'u takim a takim...", ale zdecydowania niefajnie gdy wysyłasz pocztę a ona od razu leci do /dev/null 😦 ## Soft of the Year Award DevFeed: [Soft of the Year Award]() Original publisher: [Read original article]() Published: 2008-12-19T00:00:00Z Content type: news Language: en Sources: [Front Page on ReactOS Website]() Topics: [ReactOS](), [Software]() Tags: [free](), [mail](), [open-source](), [os](), [react](), [reactos](), [results](), [software](), [win32](), [winapi]() ### AI overview ReactOS won second place in the Technologies category of the 2008 Soft of the Year national Russian software award, based on people's voting conducted by Mail.Ru. ### Source excerpt "Soft of the Year 2008" Award "Soft of the Year 2008" is a national Russian software award given annually to the best computer software.
