SMTP Error - 501 Syntax error / Bogus Domain

[Jason Dax]

I'm using wingate as POP3 Mail Server. I have installed WG 5.2 w/Kaspersky Antivirus Plugin. As I explain in another post, I have my own domain installed w/DNS server BIND 9.2.3.

I can receive mails from outside my network. If I connect from the PC in home, I can send and receive mails trough the WG POP3 & SMTP server.

But, INSIDE my network, I can only receive mails from outside. If I wanto to send mails, the WG send it back to me. Mostly gave me this two errors:

"501 Syntax error in parameters or arguments"

"domain bogus or does not exist"

Below Transcript a piece of the SMTP log generated when I send mails. (I cut date & hour)

Some Emails sent to my WG server account from outside the network aren't reaching destinations. Below transcript a piece of the SMTP log:

BTW, I have enabled the open relay detection, using NAT and trasnparent redirection.

I think the problem is inside the Wingate config, but keep wondering if mi actual BIND config has something to do with this...

Just an update to the problem: I take down all the policies I have enabled in Wingate, just in case one of them was interfering with SMTP.

When I disabled the java auth, i was able to send mails, at least mails to the most important information, outside the network.

Why java auth interfere with smtp??? I will keep testing, and update this thread when I have solid results.

[Jason Dax]

It's a fact: Java Auth has something interfering with smtp services.

The server has running till now 3 hrs, with no problems at all. Every mail sended and received are reaching destinations without problems.

Maybe the Qbik team can take a look at this issue, I don't know if was something I set up wrong or if this is a bug in WG.
