I could not find any official place where ReturnAddress is documented even though it is used at quite a few places in the RTL, VCL, FMX and 3rd party libraries like DUnitX, Spring4D, JCL, ReportBuilder, TeeChart.
I tried searching it in the contexts of Delphi 2007, Delphi 2009, but there is only a [Archive.is] different System.ObjAuto.TParameters.ReturnAddress documented in XE2 and higher.
procedure Abort; begin raise EAbort.CreateRes(@SOperationAborted) at ReturnAddress; end;
There is a (usually broken*) ReturnAddr function used in various places of the RTL/VCL/FMX and (therefore wrongfully copied) in many other peoples code.
function ReturnAddr: Pointer; // From classes.pas asm MOV EAX,[EBP+4] // sysutils.pas says [EBP-4], but this works ! end;
Related to the above is the documented ExceptAddr.
I’ve used this in my ExceptionHelperUnit to build a GetStackTrace function in the example gist below.
I found these posts documenting the behaviour of the above intrinsic functions and more:

[WayBack] I love installers that can download and install in parallel threads. Embarcadero and Zypper can learn from this. – Jeroen Wiert Pluimers – Google+
Most Linux distributions have package managers that can do this (apt and yum can), but OpenSuSE zypper (actually ZYpp) cannot even download packages in parallel:
Embarcadero is in the same state as zypper.

A few notes for managing the users that should be allowed to send mail via sendmail using TLS authentication.
Most of it is derived/summarised for [WayBack] SMTP AUTH in sendmail 8.10-8.13 and [WayBack] Creating Users for a Postfix-Based Mail Relay – Scott’s Weblog – The weblog of an IT pro specializing in cloud computing, virtualization, and networking, all with an open source view

NETUNIX NEWDB NIS NISPLUS PIPELINING SASLv2 SCANF SOCKETMAP/etc/passwdSASLv2 or older. For SASLv2 they are:
/etc/sasldb2 has the users/passwordssasldblistusers2 lists the userssaslpasswd2 manages usersFor instance, this commands creates a new user for use with sendmail:
# saslpasswd2 -c -u example.org firstname.lastname
Password:
Again (for verification):
firstname.lastname@example.org: userPassword
....................firstname.lastname@example.orguserPassword
For future reading:
not found in sasldbI thought I needed this so I could add an alias @pluimers.com to my gmail box, as I read only the accepted answer at [WayBack] Add new alias to Gmail without SMTP (forwarding-only address) – Web Applications Stack Exchange pointing to:
[WayBack] External Addresses No Longer Use Gmail SMTP ServersI should have read the second answer at [WayBack] Add new alias to Gmail without SMTP (forwarding-only address) – Web Applications Stack Exchange:
As of writing, however, you can simply use the Gmail SMTP server, as long as you use [WayBack] Google two-step authentication.
So just for completeness, the full steps:
- Gmail settings, Accounts and Import tab.
- Add another email address you own
- Type name and email address to be added.
- For SMTP Server, put
smtp.gmail.com- For Username, your full Gmail address including
@gmail.com- For password, provide an App Password generated in Google Accounts at https://security.google.com/settings/security/apppasswords
- Leave Secured connection using TLS selected as is.
- Add Account
