Dear,

I've read something interesting recently, so I decided to show it to you. It is something really surprising, please take a look <http://copy.eawebholdings.com/aekvlcx>

Thanks for your consideration, Sascha.Hestermann

sorry to inform you but the link leads to a scam site that has been doing the rounds for quite some time.

That's indeed a spam mail and it wasn't sent by me. As far as I can tell they faked the sender and used my name and mail address.

Looking as the source code of the mail reveals it was sent by 109241132252.raciborz.vectranet.pl via mailhost.mobimail.mobitelnet.lk, so no Gmx was involved.

Since a few month I have seen several of such mails and also get "Undelivered Mail Returned to Sender" mail from time to time for mails I did not sent.

I don't think I can do anything about that as the mails are neither send by me nor by my computer.

Hi

Sounds like backscatter mail;
Sender is spoofing your email; as long as you have valid spf, and dkim for the sending domain the spoofed email should be picked up by most well configured mail server as not originating from sender and not deliver; sometimes the mail server may send a message back to your server informing you that an email was received that failed spf and dkim and was not delivered.

An analogy would be somebody sending a letter to an unknown person and placing your home address as the sender on the envelope; the person it was sent to opens it; and send back 'return to sender'; you then get the letter as your home address is on the letter,having not sent it in the first place, very annoying.

Sometimes an email or domain can be attacked in this way to send out spam/viruses etc, and by having valid spf/dkim etc should reduce the possibility of this happening; however one thing that you will need to check regularly is that you do not get black listed use something like mxtoolbox to check your domain is not black listed; as if your getting attacked in this way and spam/viruses are 'appearing' to come from your domain; mail servers can be configured to auto report this activity to the likes of protected sky etc causing a blacklisting; once your blacklisted you will have problems sending to the likes of hotmail,gmail,aol,yahoo etc as well as company mail servers that use these blacklisting services as blacklist filters.

if you getting problems sending to gmail/yahoo/hotmail,outlook, live etc. Make sure that you have signed up to the bulk mail sending service ( or something like that; it is specific to each one so may take some googling) so that they do not block you dead; hotmail,outlook,live etc if you get black listed can take some time to get cleared as it is not automated and is done by human and you will have to jump through some hoops to clear it.

I come across this a lot; it seems to have escalated in the last 6 months. I have one mail server that is only confirming less than 0.2% as valid emails a months; the rest 99.8% is backscatter/spoofed emails; that you have no control over as you have not sent them. On this one server it was getting blacklisted twice a week; I even took the server down for a 2 week period; and it was getting blacklisted during this period.

Just food for thought.
Might be of use.

I've used AuthSMTP for years to send all of my email to avoid black list problems.

If you are from windows a good antivirus can help

For testing purposes, i want to create a form at runtime with chained panels - to make it simple.

I use this code

  // Create components
  ATestForm :=  TForm.Create(nil);
  ATestForm.Name:= 'Main';
  // Create a Panel
  ATestPanel := TPanel.Create(ATestForm);
  ATestPanel.Parent:=ATestForm;
  ATestPanel.Name:='PanelA';
  ATestPanel.Caption:= 'Panel';
  // Create in the panel a panel (to see the chain)
  ATestPanelSub := TPanel.Create(ATestPanel);
  ATestPanelSub.Parent := ATestPanel;
  ATestPanelSub.Name:= 'SubPanelA';
  ATestPanelSub.Caption:= 'Sub Panel';

but in the ObjectInspector (used at runtime) i see only the PanelA, not the nested ATestPanel. What do i wrong or have misunderstood ?

What is the differnt to Lazarus at desdigntime ? When i place there a a Pnale in a Panel it works.

Andreas

Owner must be the form:
ATestPanelSub := TPanel.Create(ATestForm);

I didn't know you can use the object inspector to inspect controls/components in runtime. How to enable it? Is this documented somewhere?

Yes, Lazarus/examples/objectinspetor/ is an example. My tests based on this and mine is here https://github.com/afriess/LazarusBug0032919 because i am searching for a problem of using components with published interfaces, see bug

0032919: Components with published properties of type "interface" does not work, Access violation in IDE

My try is to isolate the problem completly, and i found only very basically tests for the ObjectInspetor itself. If there are tests pls correct me. So i want to write code to test this without recompiling and debugging Lazarus itself.
