Dostałem odpowiedź, że tutaj widać limitowanie pingu tylko na routerze i wszystko jest dobrze. Po podbiciu ticket przejęła nowa osoba która chciała więcej testów więc pokazałem packet loss ~10% niezależnie od tego jaki host pinguję oraz test transferu do ich wewnętrznego serwera gdzie transfer nie przekracza 50mb/s. Sprawa została przekazana do "premium technician" według którego Grzecznie wysłałem jeszcze raz i dopiero teraz sprawa została poszła do 'network team', który stwierdził Nie mam wykupionej obsługi premium ale już w upc lub netii łatwiej jest się przebić przez pierwszą linię supportu. Propozycję rozwiązania problemu zostawię bez komentarza...

Start lts sprzed kilku lat i szczerze mówiąc nie wiem co dokładnie oznacza ich gwarancja łącza bo nie mam dużych potrzeb i nigdy nie musiałem się tym interesować, ticket założony dzisiaj rano ale jak na razie brak odpowiedzi. Tak to teraz wygląda.

Ostatnie kilkanaście dni to jest jakaś masakra - wszystko zapchane i nawet poza godzinami szczytu gubi pakiety bo linki im nie wyrabiają. Teraz maksymalny transfer z serwera we Francji nie przekracza 200kb/s...

Jasne że nie, rspamd jest dużo bardziej zaawansowanym narzędziem, chyba nawet potężniejszym od spamassasina (którego reguły można bezpośrednio zaimportować) tylko jeszcze mało popularnym. Właśnie postawiłem na serwerze z postfixem i raczej tak to powinno działać chyba, że masz naprawdę duży ruch to warto również wykorzystać redis (szybka baza nosql) do cachowania.

Rspamd jako dużo wydajniejsza alternatywa dla spamassasina oraz rmilter dodający limity, greylisting, podpisy dkim itd. Projekty zapowiadają się bardzo fajnie i są szybko rozwijane ale ciężko znaleźć królika doświadczalnego który się z tym bawił i mógłby stwierdzić czy już się nadaje na produkcję. Ktoś testował? https://rspamd.com/ https://github.com/vstakhov/rmilter

Też macie ostatnio problemy z łączem? Jakieś straty pakietów, okresy większych pingów, a na weathermapie wszystko wygląda dobrze.

To chyba troszkę mniej niż 11 gb, możesz spokojnie podbić wartości cache Warto nałożyć indeksy na wszystkie joiny

Przeglądam internet i znalazłem kilka opinii, że logowanie/replikowanie w trybie mixed może generować błędy, spotkaliście się z czymś takim?

To już kolega wyżej zaproponował logwatch chociaż ja tam wole zwykły grep i wc do liczenia

Poza poziomem optymalizacji są jeszcze flagi które robią większą różnice (np. avx) więc jak umiesz dobrać odpowiednie ustawienia zyskasz na wydajności.

Ostatnio zauważyłem, że dużo spamu przychodzi z błędnymi nagłówkami, w jaki sposób można to zablokować na poziomie postfix? Delivered-To: kontakt@get24.org To: <test@enmix.pl>

nie chodzi o ustawienie spf na mojej domenie. przykładowo email zostaje wysłany z adresu nadawca@gmail.com, dochodzi do odbiorca@domena.pl gdzie jest przekierowywany na adres odbiorca2@wp.pl. Problem polega na tym, że serwery wp.pl odrzucają taki email ponieważ ip serwera domena.pl nie mieści się w spf`ie gmail.com

Skonfigurowałem postfixa aby przekierowywał pocztę przychodzącą do abc@domena.pl na adres abc@wp.pl jednak przy wysyłaniu z kilku serwerów o bardziej restrykcyjnych ustawieniach SPF maile są odrzucane z komunikatem: 550 BLAD SPF - zobacz strone / SPF Error: Received-SPF: neutral (smtp.wp.pl: 91.121.7.45 is neither permitted nor denied by domain of gmail.com) client-ip=91.121.7.45; envelope-from=przyklad@gmail.com; Pytanie brzmi jak ustawić postfixa aby przekierowania nie kolidowały z SPF`em - najlepszym rozwiązaniem wydaje się SRS ale z tego co widzę nie ma implementacji dla postfixa.

Identyczna sytuacja występuje na lighttpd więc jest to problem z ograniczaniem ilości jednorazowych połączeń z danego ip. Problem natomiast nie występuje przy testowaniu na localhost. Pytanie brzmi czy mam coś namotane w konfiguracji kernela (o ile można coś takiego w ogóle zrobić) czy jest to standardowe ograniczenie nałożone przez serwerownie?
