I am often asked whcih blocklist providers do I use / trust not to get mail filtered becouse of bad blacklist provider.
On my servers I am using three lists (sorted by quality – my personal opinion 🙂 ):
zen.spamhaus.org – a combination of three spamhaus.org lists (SBL, XBL and PBL)
bl.spamcop.net – Spamcop blacklist
list.dsbl.org – Distributed sender blackhole list
I use this three lists without getting in troubles – at least for now. I suggest that you regularly check your SMTP logs to see how list are working.
I always notify sender that it was blocked by a blacklist.
Here is an example from and Exchange 2007 SMTP recieve log:
> “220 mail.mydomain.com Microsoft ESMTP MAIL Service ready”
< EHLO [87.69.94.190],
> 250-mail.mydomain.com Hello [87.69.94.190],
< MAIL FROM:<cathiFerm@flagpeakproperties.com> SIZE=656,
> 250 2.1.0 Sender OK,
< RCPT TO:<xxx.xxx@mydomain.com>,
> 550 5.7.1 Your IP is blacklisted. http://www.spamhaus.org,
< QUIT
> 221 2.0.0 Service closing transmission channel
Z veseljem vas obveščam, da bomo do konca decembra 2007 postavili bivalne kontejnerje v katerih bomo aktivisti Kulturnega in Multimedijskega centra Mostovna vzpostavili novogoriško hišo poskusovv. V hiši bodo predstavljeni fizikalni, elektro, računalniški, akustični in podobni eksperimenti… V primeru, da imate kakšen konstruktiven predlog se priporočamo. Odprli smo tudi spletno stran:
Trenutno na strani lahko sledite le novostim, ki jih objavljamo na forumu… V kratem video posnetki poteka dela.
Se vidimo med eksperimenti! 🙂
Večkrat se mi je zgodilo, da se je v podjetju strežnik nekako “zamrznil” za minutko ali dve nato spet sprostil nikakor pa nisem uspel najti razloga za takšno dogajanje, saj se je to zgodilo večkrat na dan ob različnih urah. Izkaže se, da do takšnega pojava pride v primeru, da uporabniki v svojih Outlook odjemalcih uporabljajo arhivske mape .PST, ki jih imajo shranjene na strežniku. Zaradi specifičnega delovanja .PST datotek pride do “zamrznitve”. / Sometimes it happen that servers “freeze” for minute or two without any reason. Well the reason is “hidden” in .PST files that users open in their Outlooks over the network. There is an KB article that describes the problem:

If you want to get NT Backup logs to your mailbox you can take advantage of IIS SMTP pickup folder or Exchange pickup folder installed on your server. Pickup folder “grabs” generated mail message and sends it to the address. This utility allows you to create VBS and BATch file that you need to complete this action. You just need to run the utility and then to schedule BATch file. If you would like to change something you can do it as the source is published. / Ce zelite poročila (log datoteke) programa NT backup poslati na vaš e-mail naslov lahko izkorstite IIS-evo SMTP pickup mapo ali pickup mapo vasih Exchange streznikov (2000, 2003, 2007). Iz Pickup folder-ja SMTP servis “pograbi” zgenerirano mail datoteko in jo nato dostavi na elektronski naslov. Moje orodje omogoca izdelavo VBS in BATch datoteke, ki pripravita vse potrebno za izvršitev takšne akcije. Po tem, ko zaženete orodje in izdelate konfiguracijski datoteki pripravite scheduled task s katerem ob določeni uri poganjate BATch datoteko. Ce zelite v programu kaj spremeniti to lahko naredite, saj je poleg izvršilnega programa (.exe) objavljena tudi izvorna koda.
After updating some SBS servers 2003 I noticed that Exchange System manager crashes if I do click help. The problem is that Internet explorer 7 – which was installed during Windows Update changes the version of Psapi.dll which is used by Exchange system manger (older version) and by IE7. To solve this problem you just need to / Po posodobitvah sistemov SBS 2003 sem ugotovil, da se Exchange System Manager “obesi”, ce v njem pritisnem na tipko Help. Tezava je v tem, da tako IE7 kot Exchange 2003 izkoriscata Psapi.dll, ki se pa med njima razlikuje. Za rešitev težave sledite spodnjim navodilom:
1. Stop the Microsoft Exchange System Attendant service (dependent services wil be also stopped) / Zaustavite servis Microsft Exchange System Attendant (pri tem sem bodo zaustavili še “odvisni” servisi).
2. Stop the IIS Admin Service (dependent services will be also stopped) / Zaustavite servis IIS Admin Service (pri tem se bodo zaustavili še “odvisni” servisi).
3. Rename the file Psapi.dll to Psapi.dll.tmp (or whatever) which can be found in your .Exchsrvrbin directory // Preimenujte Psapi.dll v Psapi.dll.tmp, datoteko pa najdete v mapi .Exchsrvrbin. <be> 4. Start stopped services / Ponovno poženite zaustavljene servise
You probably encountered CAPTCHA in form of distorted letters and numbers when you tried to register to some online forums, free e-mail providers and so on. It was invented in late 90’s and as a term spoted on the internet in 2000. More about it’s history can be found here. Most of new applications (formus, blogs …) already implement CAPTCHA as a system for preventing bots to automaticaly sign in into your web aplications and then spam or gather information. On the official Captcha website http://www.captcha.net you can get the number of CAPTCHA-s solved around the world in one day. The number is around 60 milion CAPCTHCAs per day that mean 150 000 working hours. The inventive scientists at CAPTCHA.net invented a new system called reCAPTCHA that uses words (pictures of words) that were not translated from the scanned books using OCR programs so they are solved by humans on the internet. In this way we are making two good things – protecting our online application and at the same time help solving the words from a scanned books so we are making process of digitalisation of books faster.
You can use CAPTCHA or better new product reCAPTCHA with all your online applications like MediaWiki, WordPress blog, phpBB … You can also protect your mail if published on a web site by using Mailhide – your address is partly hidden and can be revealed only by solving reCAPTCHA.
Verjetno ste se pri uporabi internetnih storitev že srečali s čudno popačenimi črkami in številkami v primerih, ko ste se želeli prijaviti na kakšen forum, oddati kakšen komentar v katerega od blogov, narediti e-mail naslov na kakšnem javnem servisu … Aplikacija, ki izdeluje takšne slike in jih uporablja za ugotavljanje “človeškosti” uporabnika se imenuje CAPTCHA – avtomatiziran test za določanje “kdo je človek” in “kdo računalnik”. Razvili so jo konec devedesetih let, na internetu pa se je pojavila v letu 2000. Več o zgodovini projekta si lahko preberete tukaj. Večina novih spletnih aplikacij že vsebuje takšen sistem, s katerim preprečuje avtomatično prijavo “robotom”, ki po spletu iščejo forume, bloge in podobne aplikacije preko katerih potem pošiljajo neželena sporočila ter iščejo e-mail naslove, ki jih kasneje ravno tako uporabljajo za pošiljanje neželenih sporočil. Na uradni spletni strani projekta CAPTCHA http://www.captcha.net so izračunali, da se dnevno razreši približno 60 milionov takšnih testov (ko se ljudje prijavljajo na različne storitve) kar preračunano znaša približno 150000 delovnih ur na dan. Inovativni razvijalci projeta so zadevo razvili in jo poimenovali reCAPTCHA – ta sistem pa v bistvu rešuje dve stvari na en mah – preprečuje zlorabo naših spletnih aplikacij ob enem pa ljudje, ki rešujejo test pripomorejo k razreševanju težav, ki nastajajo ob digitalizaciji knjig. Programi za prepoznavanje zapisa (OCR programi) včasih nepravilno razrešijo besedilo. Besede, ki jih program ne zna razbrati se uporablja v sistemu reCAPTCHA. S tem v bistvu ljudje – uporabniki interneta – pospešujemo digitalizacijo knjig.
Program reCAPTCHA lahko uporabljate s katerikoli spletno aplikacijo. Za nekatere so razvijalci že pripravili t.i. plugine oziroma odseke kode s katero zadevo relativno enostavno implementirate. Poleg formumov, blogov in podobnega pa lahko zaščitite tudi vaš e-mail naslov, ki ga objavljate na spletnih straneh. Mailhide poskrbi, da je delček vašega naslova skrit – odkrijejo ga pa lahko le ljudje, ki rešijo reCAPTCHA test.
