Dotaz: Postfix zrezava jednemu uzivatelovi maily

[eth4rendil]

Dobrý deň,

mám taký divný problem. Jednemu uživatelovi chodia niekedy nekompletne maily. Proste v polovici alebo na zaciatku ten mail odsekne a nepokracuje dalej. Tento mail je orezany tiez na serveri. V logoch nie je nic podozrive:

Vôbec nemam tušenie čo to može byť, žeby clamav? Alebo disclaimer - ten mi pridáva vždy na koniec mailu text... ale kode (nižšie) nie je nič take čo by to mohlo robiť :F a prečo prave tomuto jednemu, vôbec tomu nechapem.....

 

Viete niekto poradiť? Ďakujem pekne

disclaimer:

/etc/postfix/disclaimer

#!/bin/sh
# Localize these.

# Start processing.
cd $INSPECT_DIR || { echo $INSPECT_DIR does not exist; exit

cat >in.$$ || { echo Cannot save mail to file; exit $EX_TEMPFAIL; }

Pokud je to reprodukovatelne, neni nic jednodussiho nez zapnout vetsi 'ukecanost' jednotlivych komponent a pote je zkouset vypinat. Postfix takovehle veci nedela, ja bych si tipnul ten disclaimer. Zkus vzit vzorovy mail, ktery ti neprosel cely, a prohnat ho tim disclaimerovym skriptem.

 skúsil som ten disclaimer vypnúť, ale začalo to robiť znovu... nechápem tomu. Môže také niečo robiť clamsmtp?

Není problém v délce řádku u textu dislclaimeru (či celého mailu)? Postfix má limit pro maximální počet znaků na řádce. (/etc/postfix/main.cf, direktiva line_length_limit = 102400 <-- například).

Měl jsem navíc podobný problém s maily, ve kterých se citovaly původní zprávy. Některý mail klient nemusí správně ukončovat řádky a nasypat "všecko za sebe".
