simulate smtp session
Having problems with sending mail?
You might want to try to simulate a smtp session to see what goes wrong exactly.
Start a msdos prompt and type:
C:\WINDOWS>telnet smtp.xs4all.nl 25
Your smtp may be different offcourse.
Trying 194.109.6.51... Connected to smtp.xs4all.nl. Escape character is '^]'. 220 smtp-vbr11.xs4all.nl ESMTP Sendmail 8.13.8/8.13.8; Mon, 14 Sep 2009 15:03:50 +0200 (CEST)
Type “helo” followed by your domain
helo bogusdomain.nl 250 smtp-vbr11.xs4all.nl Hello xxxxxxxxx [a.b.c.d], pleased to meet you
Type “mail from:” followed by your email address
mail from:hugo@bogusdomain.nl 250 2.1.0 hugo@bogusdomain.nl... Sender ok
Type “rcpt to:” followed by your email address
rcpt to:hugo@bogusdomain.nl 553 5.3.0 hugo@bogusdomain.nl... Relaying denied,Authenticate with your username and password first
Now we see what is wrong here. This server doesn’t allow me to relay.
Type “quit” to exit.
quit 221 2.0.0 smtp-vbr11.xs4all.nl closing connection Connection closed by foreign host.
If you didn’t get an error after “rcpt-to:”, continue with:
250 2.1.5 Ok data 354 End data with <CR><LF>.<CR><LF> hello hugo . 250 2.0.0 Ok: queued as 60D2A4A24A quit 221 2.0.0 Bye
Mail should arrive now.

Set ownership recursively
One of my customers has a directory filled with home directories of all students.
Due to some copying, the ownership of all files was set to “administrator”.
Since quota was enabled, quota usage of all students was practically 0.
They needed a fix to set ownership back a.s.a.p.
I created the following batchfile. You need the subinacl utility from microsoft though.
- Put the script in the directory you want to make the changes for.
- Usernames must match the directorynames.
@echo off for /f "tokens=*" %%a in ('dir /b /ad') do subinacl /file %%a\*.* /setowner=%%a pause
Maybe you want to grant the users (just to be sure)
@echo off for /f "tokens=*" %%a in ('dir /b /ad') do subinacl /file %%a\*.* /setowner=%%a for /f "tokens=*" %%a in ('dir /b /ad') do subinacl /file %%a\*.* /grant=YOURDOMAIN\%%a pause

Hide from Exchange address list
Sometimes you just want people not to show up in your address list.
Here’s a simple vbs script that does the trick.
REM On Error Resume Next groep = inputbox("Which group?") set objRootDSE = GetObject("LDAP://RootDSE") strdomainname = objRootDSE.Get("defaultNamingContext") set objgroup = getobject("LDAP://cn=" + groep + ",cn=users," + strdomainname) objgroup.GetInfo arrmember = objgroup.GetEx("member") for each objmember in arrmember set objuser = getobject("LDAP://" + objmember) objuser.MSExchHideFromAddressLists = TRUE objuser.SetInfo next
