Hi,
shortly after (K)ubuntu Edgy Eft came out, I installed it
on my brand-new PC (32bit Version, so as to be able to use
flash and w32codecs without going through chroot).
Now, I've had the surprise at least three times that the
machine would just suddenly start accessing the disk a
lot, and essentially freeze - for a good while.
Just earlier tonight this happened again, while I had
"top" running, as well as the superkaramba theme "aio".
Thanks to these two, I got to see how "kio_thumbnail"
simply gobbled up resources (CPU, RAM and swap maxing
out - we're talking Athlon X2 4600+ with 1GB RAM and
1GB swap) in no time at all, no chance to even get a
shell to kill the process.
I was using konqueror as filemanager at the time, but
not in any directory with lots of files.
I googled a bit, but didn't find much interesting info
on this issue. Is anyone aware of specific problems
with kio_thumbnail?
TIA, Eric

What I did so far is specify
local_recipient_maps=mysql:/etc/postfile/filename.bla
with a simple query to check if the requested mailbox exists... I will
see tomorrow if it helped...
Thanks for your input!

this parameter was actually switched off by default, but then we got
problems because the server sent unsolicited bounces, because the spam
was sent with faked From-adresses of real domains (and we got
blacklisted because of sending these bounces)...
But we changed/tried a lot of config settings since then, so if you will
tell me I should switch it off again with my current config I will try
that... :-)

Hello Folks,
a mailserver we administer is currently under heavy attack by spam, that
is, we get *tons* (100+/second) of messages to addresses like
johndoe(a)mydomain.lu.
This mailbox johndoe of course does not exist. Here an extract of the
log:
Nov 1 19:55:53 roma postfix/virtual[21113]: 780104B0E7:
to=<root(a)mydomain.lu>, orig_to=<postmaster@localhost>, relay=virtual,
delay=341690, status=SOFTBOUNCE (unknown user: "root(a)mydomain.lu")
Some how it seems the send message remains in one of the postfix queues,
and causes a general slowdown of mail handling of the server.
I just want it to drop these (anyway) undeliverable messages, but fail
to set this up...
The main.cf is attached. Help is appreciated... / me desperate ... :-|
regards,
Yves
p.s.
I am not an expert with postfix, the mailserver runs fine since 6 month.
The mentioned problems started 3 days ago only.
