Hello,
I have customers, where sending emails ist blocked by a error 550 and a 
message that server is in a blacklist. But this only happens with asinet, 
and not with Outlook, Why ?

Are you sure that the same SMTP server is being used in both cases?

What ISP is used? Normally the ISP is responsible to get his servers off
the blacklist.

Hello Thomas,
thank you, Bruce pointed me to something that could be the reason.

Rudolf

Most probably you need to set the permission for the SMTP protocol to relay 
mail either from your workstation, if that is where it is originating, or 
from the server itself, if you are generating the email in that computer. 
If a Microsoft OS, in the SMTP Protocol, under Access, set the Relay 
Restrictions to allow relaying from the LAN IP's of your chosen computers. 
It sounds odd, but the server has to be granted permission to relay emails 
orginating from itself.

Also, you can put any domain name, real or imaginary, in the From and Reply 
of the email's header, i.e., you can be a spammer.  However, many ISP's and 
corporate email servers now do a reverse DNS lookup of the sending network's 
IP address in the email header, and, if the sending domain name is not 
resolved from the check, then the receiving server will mark the email as 
spam.  Make sure your mailer server's domain registration has an A record 
which resolves to its IP address.

Hello Bruce,
thank you, now it is clear for me, it runs on the notebook of a customer, 
but with  my email accound settings. So the DNS lookup will be the problem. 
I will change the account settings and test it.

Hi,

I have a automatic email send function in one of my apps.
This will send the XbbError.log to my.
For this purpose I just made me a new MyProgrammName@gmx.de Adress and

No problems yet.
