Hi all.

I'm working on an installation of .Net MailServer and when I enable the DNSBL no mail gets through at all, and the following error appears in the logs:

550 Object cannot be cast from DBNull to other types

Does anyone know why this would happen and what can be done to resolve it?  It occurs if I have just one or all three enabled.

Thanks,
Dave

This has now been resolved. I just enabled them again and they worked. Strange

Mail Server v1.0.5.8

Mail Server

  • Mailbags now have an option to accept mail only when specified server is down - will help to fight with spam which attempt to deliver mail bypassing the main server;
  • When delivering mail, if main exchanger returns 4xx reply (temporary problem), the server will not try other exchangers, will retry later the main exchanger;
  • Server options moved from registry to a XML file. 64 bit versions of Vista and 2008 server appear to be having access rights problems to the Windows registry, and the change will make our server more compatible with 64 bit versions;
  • Added an option to specify the number of lines on the log screen, when using the user interface. Was causing memory problems if left running for long time;
  • Fixed couple of problems, which were showing when SQL server was set up to use case sensitive SQL statements;
  • Made changes in the remoting interface to allow logging in using aliases;

Web Interface

  • Made changes to allow logging in using aliases;
  • When viewing folders, web interface now displays the name of logged in user;

FTP Server v1.0.1.6
  • Server settings have been moved from registry to the XML file, which will be located in the common application data directory. 64 bit versions of Windows were having trouble writing into the registry; similar change is coming to the mail server;
  • If used, XML files (Users.XML, Groups.XML and ServerOptions.XML) will also be moved to the common application data directory;

FTP Server v1.0.1.5
  • When performing active data transfers on systems with multiple IP addresses, data connections were using first available IP address, rather than one on which the control connection was active. It was causing confusion with firewalls and routers;

Web Mail Hosting

I am considering to start web mail hosting service for ArGoSoft Mail Server .NET: mail server will be installed on your computer, while the web interface - on ours. It will save the hassle with setting up the web interface, and keep updating it.

Please vote here wheter you are interested in such a service.

  • Each session can have a limit of RCPT TO commands Options - Server Settings - General . This feature was present in the Pro version, but was missing in the .NET.
  • Now allowing to specify the lifetime for remoting validation token, can be useful to extend the length of web interface sessions (Options - Server Options - Advanced);

Web Interface

  • Updated to allow the domain group administrator to update Max Rcpt To commands (see above);
