Hi ALl, I am using QMAIL to send verify email to users registered in my website.no problem except one website.I am send the email via a perl script via open(MAIL, "|$SENDMAIL -t -oi") ,$SENDMAIL is /usr/sbin/sendmail and was link to /var/qmail/bin/sendmail. the problem is when I send to [EMAIL PROTECTED](NOTE:not problem about that domain name,when I send to [EMAIL PROTECTED],its OK) the error msg return by my QMAIL is as following: Hi. This is the qmail-send program at qiji.com. I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. <[EMAIL PROTECTED]>: 202.96.44.17 failed after I sent the message. Remote host said: 552 message is not welcome to our host,maybe too big (#5.3.4) --- Below this line is a copy of the message. Return-Path: <[EMAIL PROTECTED]> Received: (qmail 7854 invoked by uid 99); 14 Oct 1999 08:26:57 -0000 Date: 14 Oct 1999 08:26:57 -0000 Message-ID: <[EMAIL PROTECTED]> From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: WELCOME..... .......... ......... ... OK.I have 2 question. 1.the verify is less than 1K,why got 552 message?I'd check it w/ my own account there and my mailbox is empty there so its not really exceed the box size. 2.weird problem is that,when I resend this email via my own account in my server,via hmailto:[EMAIL PROTECTED] to that [EMAIL PROTECTED],its OK!.why? Thanks in advance! -- ºéÁ¦(Mr. Li Hong) ========================================== Ææ¼£ÍøÂç, Internet Miracle China ÍøÂçÇà´º, Ææ¼£ÎÞÏÞ ========================================== http://www.qiji.com/ Email: [EMAIL PROTECTED] Office:(010)86251065 Cell: 13001051160
