AKJ> Настораживает само отношение - несмотря на имеющиеся проблемы, более 3-х AKJ> лет без багфиксов блин..... я ГОВОРИЛ!!!! про вещи типа вот такого : взято из mail list'a по exim'y http://www.exim.org/pipermail/exim-announce/2001q3/000037.html ---------------------------- 1. An address longer than 256 bytes could cause Exim to crash. Change 38 for 3.30 limits local addresses to 512 bytes (the RFC limit is 64bytes@255bytes and SMTP addresses have always been limited), so the relevant vector has been increased to 512 bytes. ---------------------------- или вот это, из postfix'овского change log'a : ------------------------------ 20020201 [skip] Bugfix: backed out a null-length address panic call by ignoring the problem, like Postfix did in the past. File: global/resolve_local.c. ------------------------------------- А теперь по поводу DoS'a пара фраз из спискa по qmail'у: ------------------------------------- > Thus I am less interested in how to fix the DoS. What I want, was > just report this problem to whoever interested in fixing the problem > for other qmail users. As you will see if you scan the archives, the "problem" has already been fixed. In fact, there is no problem. Just user error. ------------------------------------- взято вот тут: http://www.ornl.gov/its/archives/mailing-lists/qmail/2001/11/msg00430.html Думаю вопрос снят? сори но не удержусь, из предедущего : ------------------------------------- Yes, yes, yes. Read the archives... ------------------------------------- :) -- Best regards, Dmitry mailto:blood_j@mail.ru
