Dotaz: Pomaly postfix

[vlada]

Ahoj, asi pred mesicem jsem nainstaloval na server postfix a vse bezelo v poradku. Ted jsem pres nej zkousel odesilat postu s prilohou a odeslani trva nekolik minut i u prilohy velikosti v par stovek KB. K serveru jsem pripojen 100 mbit linkou a server je do internetu(nemelo by hrat roli) 20 mbit linkou. V logu neni zadna zvlastni hlaska. Stejne tak pflogsumm nehlasi zadnou chybu. Takhle vypada konfigurak postfixu. Diky za rady

hmmmm... a co zkusit nahodit Amavis v debug modu a pozorovat, jestli se to nesekne nekde tam?

[komodo]

A nemas nejaky problem s DNS ? Caka na timeout prveho DNS s resolv.conf a potom sa pyta druheho.

[vlada]

problem neni v cekani na odeslani souboru, ale primo prubeh odesilani je priserne pomaly. Myslim odesilani z meho pocitace na server, kde bezi postfix. Soubor s 1 MB by měl být na serveru téměř hned ale takhle to trva několik minut. Navíc ftp na ten server jede rychlosti v MB/s. Zkusim kouknout na ten amavis.

[vlada]

Tak jsem zkusil pustit amavis v debug modu a nevypisovalo se nic podezreleho....pri odesilani mailu na ten server s postfixem je vytizeni jeho procesoru nekde u nuly a disk je na tom stejne, sit take. Kabel je tam 100 mbit, ale posta z meho pc na server se odesila cca rychlosti kolem 100 kbps. Zkousim to na mailech s prilohou kolem 1 MB a jeji presun na server trva kolem minuty...

[pantera]

No tak jsem zkusil trochu googlit a nasel jsem toto:
Znamenalo by to, ze se postfix pokousi dorucit mail primo - tj. od tebe primo na cilove smtp, coz by mohl byt problem... Chtelo by to sem hodit i vypis z master.cf - ja si za boha nevzpomenu, kde se to nastavuje :o)

[vlada]

zkusil jsem pustit tcpdump na tom serveru a od sebe odeslat mail a ten server pri odesilani komunikoval jenom se mnou.

[vasek125]

A není problém někde jinde? Třeba shaping portu 25??

[vlada]

to mi taky napadlo, ale shaping jsem zatim na tom serveru nedelal, firewall tam nebezi a iptables jsou prazdne :(

Takhle vypada soubor main.cf

myhostname = enkidu
mydomain = enkidu.local
myorigin = $mydomain

Tohle je urcite spravne? nemelo by tam byt napr. mail.mojedomena.cz a mojedomena.cz nebo neco podobneho?

[vlada]

odpoledne jsem to zmenil,takze myhostname je enkidu.mojedomena.cz a mydomain je zakomentovany, protoze se ty domeny natahuji z jineho souboru
