Sure you've all heard it before, because of the pipe error, no more login processes can be launched, and I have to restart the server. dovecot: Sep 13 05:50:00 Error: pipe() failed: Too many open files I first thought this was the issue with kqueue, but I've since recompiled making sure to use

Hi hoping someone can help me a little with this one. I have 2 mail servers, the incoming mail server runs dovecot and the outgoing mail server runs postfix with sasl. Lately I noticed a lot of spammers are running dictionary attacks on my incoming server and then using that user/password for sasl on the outgoing server. The weird thing is I never see on the logs the guessed

Hi This is a new one on me - I've never seen spammers attempt to use to SASL Auth to inject spam. None of the users they are trying (newsletter, dummy, test, etc.) exist, but what worries me is the illegal chars error - is this a known vulnerability in dovecot they are trying to exploit? I'm running 1:1.2.15-7 installed from apt-get.. Oct 17 15:07:16 mail postfix/smtpd[14422]: connect

When attempting to compile a dynamic language like python/java does LLVM allow a function to compile itself one at a time? In other words, can I parse a function, then gain the machine bit code, then execute without parsing the other functions related to the compiled function? Thanks, Jeff Kunkel

Spring is back in the Stockholm area. After a few day's worth winter re-runs, the sun is back and night-time temperature is at least 5 degrees celsius. Time to move out all my annual flowers and prepare the garden for summer. Sweden is famous for our annual five week holidays - by law. From june to late august, it's almost impossible to make any business decision, since there's always

This is a high traffic list as it is and it is really annoying to see that SPAM is on the rise here. I wonder how they can spam the list since each user has to be authenticated. Do spammers go through the trouble of subscribing to the list? In any case, this msg is to the list admin...could you please do whatever it takes to filter this stuff out? Thank you very much. -bakki

Hi, Some people have suggested maintaining black lists and white lists to avoid spammers and allow legitimate callers into the network. However, the problem with this method is that the spammer's IP address might change due to DHCP. Today a spammer might get aaa.bbb.ccc.ddd and lets say that I put this address in my blacklist. To my annoyance, tomorrow a legitimate caller might get

Hello. This might be a silly problem, but I'm a bit a newbie at this, and the internet didn't give me a solution to this yet.
