Hello,
yesterday I have found BUG in KMS 6.1rc1 and 6.1beta5 (tested on two computers: Windows2000 server SP4 and Windows XP SP2).

When you try to send email to "txtlbv<_at_>abuse.net" KMS will hang and CANNOT BE STARTED AGAIN!!!
Look at DEBUG log entry:
[21/Jun/2005 06:26:14][1264] {smtpc} Recipient <txtlbv<_at_>abuse.net> not accepted: 550 Forged abuse.net address in spam (#5.7.1)
[21/Jun/2005 06:26:14][1264] {smtpc} No recipient succeeded

You can see "{smtpc} SMTP reply too long". After this error KMS will stop. Until you delete the email (addressed to "txtlbv<_at_>abuse.net" or anyone at abuse.net) from mail queue, you WILL NOT BE ABLE TO START KMS!. But, you can't delete this email using ADMIN, because KMS will NOT start with this email in queue. It maybe starts when disconnected from internet, but I can't test this (I'm connected to KMS via internet over VPN). KMS will hang when it try to send this mail from queue (see the log entry above).

Why our KMS try to send email to "txtlbv<_at_>abuse.net">? Because we have received email from this address (spam - but not recorgnized) and KMS just send AUTO-REPLY (out of office)...

BTW: I will report this to KERIO, but now I'm collecting some datas from test machines...
