First Slovenian “white list” of safe mail servers / Prva slovenska “bela lista” varnih poštnih strežnikov

Leave a reply

In MMC Mostovna we have started a new technological project. This is first Slovenian white list of (slovenian) safe/trusted mail servers. The white-list is freely available but in BETA phase for now. I hope it will be ready soon. For testing just enter the name: si-whitelist.mostovna.com in your mail server and allow records that get code 127.0.0.1. You can get more info by sending e-mail to info(AT)si-whitelist.mostovna.com / V MMC Mostovna smo začeli z novim tehnološkim projektom, prvo slovensko “belo listo” varnih (slovenskih) poštnih strežnikov. Lista je prosto dostopna vendar za enkrat v BETA fazi. Upamo, da bo kmalu opravljena faza testiranj. Za testiranje liste lahko v nastavitve vaših poštnih strežnikov vpišete naslov: si-whitelist.mostovna.com in eksplicitno dovoljujete vse zapise, za katere dobite odgovor 127.0.0.1. Za več informacij smo vam na voljo na info(AT)si-whitelist.mostovna.com.

I will explain just in few words the major differences / changes that I encountered after a deployment of Microsoft Exchange 2007. / Z nekaj besedami vam bom opisal spremembe, ki sem jih srečal ob namestitvi Microsoft Exchange 2007 – sporočilnega sistema.

1. GUI and Powershell / Grafični vmesnik in “Močnostni ukazni poziv 🙂 (Powershell)”
Ok… You can do some basic stuff using GUI interface called Exchange Management Console.
In my configuration Exchange 2007 was installed on a single server so it is running:
– Mailbox role
– Hub transport role
– Client access role

Mail system DLL is invalid

S to zadevo se včasih srečam na Windows server 2003 SBS – ponavadi zato, ker je nanj instaliran Outlook 2003 – Microsoft instalacijo Outlook-a 2003 na strežnik odsvetuje / ni podprta. Outlook zamenja datoteko c:WindowsSystem32mapi32.dll – ce nanjo kliknemo z desnim miškinim gumbom in izberemo Properties lahko pregledamo različico. Za pravilno delovanje potrebujemo 1.0.2536.0. Datoteko lahko v nasprotnem primeru prepišete s kateregakoli drugega Windows 2003 server sistema.
I get by this problem on some Windows server 2003 SBS servers – mostly becouse there is Outlook 2003 installed on the system – this is not racommended and even not supported by Microsoft. You can check c:WindowsSystem32mapi32.dll by clicking right mouse button and then select properties. The version of the file should be 1.0.253.6.0. If you have different version you can replace this file from any other Windows 2003 server.

Konfiguracija DNS strežnika (forward cona) / Configuration of DNS server (forward zone)

Osnovna pravilna konfiguracija DNS zapisa in njegovo testiranje. / Correct basic configuration of DNS records and testing.

Pri konfiguraciji DNS strežnika moramo upoštevati nekaj osnovnih navodil. There are some basic rules that should be folowed when configuring DNS servers.

Vzemimo primer, da imamo domeno company.com za katero bi radi naredili DNS zapis: Let say that we have domain company.com and we would like to create DNS record for it:

1. naredimo primarno forward cono company.com / create forward zone for company.com
2. popravimo SOA zapis: / correct SOA record:
2.1 oštevilčimo po principu LETOMESECDAN01 – primer: 2007020701 / enumerate it with YYYYMMDDnn
2.2 vpišemo ime primarnega DNS streznika ter e-mail skrbnika domene – pozor v obliki ime.domena.končnica – brez afne – @ / enter the name of primary DNS server for domain company.com and its hostmaster without “at” sign – @ example. hosmaster.company.com
2.3 po potrebi popravimo časovne vrednosti zapisa / if it is needed fix the time values of the record
2.4 vpišemo DNS strežnike / enter your DNS servers
3. naredimo zapis gostitelja – A zapis strežnika, ki bo gostil storitve / create a HOST or A record for a computer that will host services
4. naredimo psevdonim – CNAME zapis, ki bo “kazal” na gostitelja. / create alias – CNAME record for aliases that will point to HOST.
5. naredimo MX zapis za domeno company.com / create MX record for domain company.com
6. testiramo delovanje z uporabo / testing:
ping
nslookup
