IMAP Proxy jest cacheuj\u0105cym serwerem proxy IMAP przeznaczonym do u\u017cycia z klientami webmail, kt\u00f3re nie potrafi\u0105 utrzymywa\u0107 sta\u0142ych po\u0142\u0105cze\u0144 do serwera IMAP.<\/h3>\n

IMAP Proxy umieszcza si\u0119 pomi\u0119dzy serwerem webmail i serwerem IMAP. Przyjmuje on po\u0142\u0105czenia od serwera webmail dla ka\u017cdego klienta i przekazuje je do w\u0142a\u015bciwego serwera IMAP. Kiedy klient webmail roz\u0142\u0105czy si\u0119, IMAP Proxy pozostawia otwarte po\u0142\u0105czenie przez okre\u015blony czas i kiedy webmail zn\u00f3w si\u0119 po\u0142\u0105czy zostaje u\u017cyte istniej\u0105ce ju\u017c po\u0142\u0105czenie.<\/p>\n

IMAP Proxy jest bardzo lekkim daemonem napisanym w C z u\u017cyciem w\u0105tk\u00f3w POSIX. Kompiluje si\u0119 i dzia\u0142a na wi\u0119kszo\u015bci system\u00f3w UNIXowych i jest dost\u0119pny w prekompilowanej wersji dla wielu dystrybucji Linuxa, jak np. Debian, Ubuntu, Gentoo i Fedora.<\/p>\n

IMAP Proxy jest wolnym oprogramowaniem<\/a>, na licencji GNU GPL<\/a>.<\/p>\n

IMAP Proxy zosta\u0142 napisany w 2002 roku przez Dave McMurtrie. W 2010 roku zosta\u0142 zaadoptowany przez zesp\u00f3\u0142 SquirrelMail<\/a>.\n<\/p>\n

<\/p>\n

Postanowili\u015bmy zastosowa\u0107 IMAP Proxy aby poprawi\u0107 wydajno\u015b\u0107 webmaila opartego na Horde\/IMP. Kompilacja, instalacja i konfiguracja IMAP Proxy nie przysparza problem\u00f3w nawet na Solarisie, poni\u017cej znajduje si\u0119 zapis sesji oraz zawarto\u015b\u0107 pliku konfiguracyjnego. Skrypt w za\u0142\u0105czeniu.<\/p>\n

Imap Proxy nie posiada zestawu test\u00f3w, wi\u0119c skoro si\u0119 skompilowa\u0142, to mo\u017cna zainstalowa\u0107.<\/p>\n
Konfiguracja programu jest prosta i nie powinna stwarza\u0107 problemu nawet niezaawansowanym administratorom, trzeba utworzy\u0107 plik \/etc\/imapproxy.conf<\/code> lub wskaza\u0107 w\u0142a\u015bciwy w opcjach przy uruchomieniu demona in.impapproxyd<\/code>.<\/p>\n

M\u00f3j plik konfiguracyjny opiera si\u0119 na warto\u015bciach domy\u015blnych, zmieni\u0142em tylko limit po\u0142\u0105cze\u0144 (cache_size<\/code>) i adres serwera (server<\/code>). Opcje konfiguracyjne opisane s\u0105 w pliku README dostarczanym w dystrybucji\/\u017ar\u00f3d\u0142ach.<\/p>\n
Po uruchomieniu proponuj\u0119 sprawdzi\u0107 czy IMAP Proxy s\u0142ucha na wybranym porcie:<\/p>\n
\r\ntelnet localhost 143\r\nTrying 127.0.0.1...\r\nConnected to localhost.\r\nEscape character is '^]'.\r\n* OK [CAPABILITY IMAP4rev1 LITERAL+ LOGIN-REFERRALS ID ENABLE AUTH=LOGIN  XIMAPPROXY] Dovecot ready.\r\n<\/pre>\n
Wida\u0107, \u017ce jest rozszerzenie XIMAPPROXY, a pod spodem wida\u0107 Dovecot ready<\/code> od w\u0142a\u015bciwego IMAPa.<\/p>\n
Je\u015bli proxy ma chodzi\u0107 na tym samym serwerze co IMAP, to musimy uruchomi\u0107 serwer IMAP na innym porcie albo proxy. Osobi\u015bcie IMAPa bym zostawi\u0142 na domy\u015blnych portach, a zmieni\u0142 listen_port<\/code> np. na 1143 w IMAP Proxy i przekonfigurowa\u0142 webmaila. To spowoduje, \u017ce normalne klienty IMAP (kt\u00f3re robi\u0105 sta\u0142e po\u0142\u0105czenia) b\u0119d\u0105 si\u0119 \u0142\u0105czy\u0107 bezpo\u015brednio do serwera IMAP a webmail b\u0119dzie korzysta\u0142 z proxy.<\/p>\n
