[vchkpw] 451 mail server temporarily rejected message (#4.3.0)
Hi, First of all I apologise for posting a question that has been already discussed, but I can't find any clues there to solve the problem. As I could see it is a permissions issue...??? http://www.mail-archive.com/vchkpw@inter7.com/msg19534.html http://www.mail-archive.com/vchkpw@inter7.com/msg19681.html I've installed simscan following step by step the README in http://www.inter7.com/simscan/README Everything looks to be alright, but when anybody tries to send an e-mail to my box it anwers: 451 mail server temporarily rejected message (#4.3.0). As an example: mail from: [EMAIL PROTECTED] 250 ok rcpt to: [EMAIL PROTECTED] 250 ok data 354 go ahead test . 451 mail server temporarily rejected message (#4.3.0) If I erase the ,QMAILQUEUE=/var/qmail/bin/simscan in my tcp.smtp everything works fine (just to discard a qmail problem). I'll appreciate any comment. Thanks in advance. Sincerely, Agustín

I know mr. sam and some other profilic people in this sphere thinks pop-before-smtp is dead, is silly and obsolete, but I can say it isn't. just add a bogus account to vpopmail ([EMAIL PROTECTED] works fine and shouldn't get you that much spam), add it as a kmail pop3 account and switch on interval checking. or you could use the filter messages if they are greater than 1 bytes option in kmail for a pop3 account. Or you could use the Precommand functionality of kmail and use something like fetchmail -c -s as you precommand line for your smtp transport. The question still, is how to make this work, not to make me start using smtp auth. If was really smart I would stop using an utterly dead (not developed since 1998), and unsupported software like qmail is and use _any_ of the others that is still alive, supported, developed and in much wider use.

Hi there, According to the author ( I have read somewhere), that this error due to unexpected exit code of Spamassassin which is not understood by simscan. I am not sure though.

Re: [vchkpw] 451 mail server temporarily rejected message (#4.3.0)
Dear Kareem, Thanks for your answer! I think it isn't the spamassassin because I've tried simscan without it (as it recommends in http://qmailwiki.inter7.com/index.php?title=Simscan/Guide for the first try) but I got the same error... If I find the solution, I'll gladly tell you about it...

[vchkpw] vchkpw fails and then succeeds!
When a user tries to authenticate itself, the first time vchkpw fails with: Dec 6 21:50:08 [vpopmail] vchkpw-smtp: password fail but then it succeeds immediatly after: Dec 6 21:50:13 [vpopmail] vchkpw-smtp: (PLAIN) login success This is very annoying, besides the fact that this only happens with Thunderbird, with other e-mail clients they give an error message and the connection is terminated. Is there any way to solve this thing? Oh.. and the greatest of all is that this only happens while authenticating for smtp relay, POP3 and IMAP work out perfectly. -- Pedro Pais Skype name: pedro.pais MSN: [EMAIL PROTECTED] Get Firefox! http://www.spreadfirefox.com/community/?q=affiliatesamp;id=3759amp;t=1
Re: [vchkpw] 451 mail server temporarily rejected message (#4.3.0)
Dear Alastair, Thank you very much for your help! I tried SIMSCAN_DEBUG=2 in my qmail init script and the logs said the lines I'm sending below. When I installed simscan I used --disable-ripmime because clamav can scan mail messages, but It seems that I must install ripmime anyway??? I'll test simscan with ripmime and after that I'll post another message telling how everything goes.

I'm sorry you're not really smart. All I can tell you is I love qmail! If qmail is utterly dead I'm a necrophiliac. Yours truly, Mikael

[vchkpw] chkuser 2.0.8 released again - 2.0.8a
A damned typing error in chkuser.c gives compile error when #define
CHKUSER_STARTING_VARIABLE is defined.
You may download 2.0.8a, or change, in chkuser.c, this line:
if (strùcasecmp(starting_string, ALWAYS) == 0) {
to
if (strcasecmp(starting_string, ALWAYS) == 0) {
Sorry for any inconvenience.
Tonino
chkuser 2.0.8 has been released,
and is available at
www.interazioni.it/opensource.
As usual, this version has been tested and is now working on my
production systems since some weeks.
This version, basically:
freeze
all important changes in 2.0.7 (closing DB connections among all)
is
more RFC compliant (NULL SENDER is now ALWAYS accepted, and all FORMAT
and MX checking defines are OFF by default)
cleans
some small bugs.
It has been released as complete release package, and as
update of previous installed versions (from 2.0.5 to
2.0.7).
Additional note:
I put on the site a small script displaying chkuser activity.
On one of my systems, I defined acceptance limits for existing (limit is
50) and wrong (limit is 5) users.
On that system, I'm facing each day several attacks, and these acceptance
limits help me rejecting them.
They are also suggesting me to implement additional features for
rejecting those IP.
Any comment on this topic is welcomed.

[vchkpw] vpopmail = 5.4.8 solaris install problem
I have identified an installation problem in the latest releases of vpopmail on Solaris 2.7 the install program used by the Makefile does not support installing multiple files in one run, and it does not error when told to install multiple files -- it simply installs the first in the list, and exits. this yields 'make install' not copying config.h, vauth.h, nor vlimits.h to ~vpopmail/include/ needless to say, this makes things _very_ confusing, when vuserinfo works, but when programs like qmailadmin dont work (because they are using include files from an older vpopmail series that were not overwritten) the following patch fixes the problem (use patch -d vpopmail-5.4.8 vpopmail-5.4.8-kisterfix): --- Makefile.am.orig 2004-12-09 00:29:58.222616000 -0500 +++ Makefile.am 2004-12-09 00:31:00.863282000 -0500 @@ -151,9 +151,9 @@ $(INSTALL) -o root -m 0444 \ config.h $(DESTDIR)@vpopmaildir@/include/vpopmail_config.h - $(INSTALL) -o root -m 0444 \ -vpopmail.h config.h vauth.h vlimits.h \ -$(DESTDIR)@vpopmaildir@/include/ + for include in vpopmail.h config.h vauth.h vlimits.h ; do \ + $(INSTALL) -o root -m 0444 $$include $(DESTDIR)@vpopmaildir@/include/ ; \ + done $(INSTALL) -d $(DESTDIR)@vpopmaildir@/doc/man_html $(INSTALL) -d $(DESTDIR)@vpopmaildir@/doc/doc_html --- Makefile.in.orig 2004-12-09 00:30:02.552653000 -0500 +++ Makefile.in 2004-12-09 00:30:30.282952000 -0500 @@ -829,9 +829,9 @@ $(INSTALL) -o root -m 0444 \ config.h $(DESTDIR)@vpopmaildir@/include/vpopmail_config.h - $(INSTALL) -o root -m 0444 \ -vpopmail.h config.h vauth.h vlimits.h \ -$(DESTDIR)@vpopmaildir@/include/ + for include in vpopmail.h config.h vauth.h vlimits.h ; do \ + $(INSTALL) -o root -m 0444 $$include $(DESTDIR)@vpopmaildir@/include/ ; \ + done $(INSTALL) -d $(DESTDIR)@vpopmaildir@/doc/man_html $(INSTALL) -d $(DESTDIR)@vpopmaildir@/doc/doc_html -- Jeremy Kister http://jeremy.kister.net/
