Most likely you are using SMTP authentication with OE, but not with ASINET... This Microsoft article sums it up quite good: http://office.microsoft.com/en-us/outlook/HA011128331033.aspx Thomas

It is no problem for me to send mail by Xbase++ & Asinet lib through my ISP's SMTP server which authentication is required. 2.) Now I need to send email through some free SMTP server (which needed authentication as well) however, it fail as i describe before ...But it success with Outlook Express ! Following are 2 mail format: A.) sendwith Asinet lib through my ISP's SMTP server B.) sendwith Outlook express through a free SMTP server (since it fail with Asinet lib) A.)

	Andreas Gehrs-Pahl	Re: Why mail 553 error on Wed, 25 Apr 2007 06:45:56 -0400 Shum, Could you post the SMTP settings in Outlook Express and the ones you use in your program (you should obfuscate the Login Name and Password, though!) Maybe this will show what the problem is. The "553" error specifies that the email was considered SPAM, and the Outlook Express email "B.)" is routed through a SPAM Proxy Server, while your ASINet email "A.)" is sent directly, without even being relayed to a different SMTP server (it appears). I suppose that the email has to come from the SPAM Proxy Server -- and probably also contain the required "HMM_xxx:" headers -- before it is relayed by the actual "21cn.com" SMTP server. As I have never seen such an "SMTP-over-Proxy-Server" approach (outside of Web-based EMail) -- neither ASINet nor SEE4XB have any settings for Proxy Servers -- I assume that the "aisp2-smtp" server (at 61.140.60.71) should be specified, rather than the actual (relaying) "smtpf1.forptr.21cn.com" server (at 59.36.102.60). But I can't find a Reverse DNS entry for it, so I don't really know. Your ASINet email "A.)" was sent directly to your ISP's SMTP server named "smtp02.hgcbroadband.com" or "smtp02.net-yan.com" (at 210.0.255.157), which means that the email didn't need to be relayed to another SMTP server. For the "B.)" email, Outlook Express connected to a "foreign" SMTP server using the credentials of "hestia33@21cn.com", and then the email was first routed through the Anti-SPAM Proxy and then relayed to your email Server by the "21cn.com" SMTP Server. In addition to some code, you could also post a Log of the failed attempt, which should look something like this: Info: Socket created successfully Info: Successfully connected to xxxx.xxx Info: Server response: 220 xxx.xxxx.xxx ESMTP server ready (or some stuff) [...] Info: Server response: 553 this mail is rejected by antispam system... Error: Unexpected response from server 5 Error: could not connect! This might help in establishing where and when the error occurred. -- Andreas --- --- Andreas Gehrs-Pahl E-Mail: GPahl@CharterMI.net 415 Gute Street or: Andreas@DDPSoftware.com Owosso, MI 48867-4410 or: Andreas@Aerospace-History.net Tel: (989) 723-9927 Web Site: http://www.Aerospace-History.net --- ---

	Shum [MingYik]	Re: Why mail 553 error on Thu, 26 Apr 2007 02:56:23 +0800 Hello All, I try to use socmapi.dll to post e-mail through OutLook Express (automatically)... (by using free smtp server ie.: smtp.21cn.com) ... But fail again ...??? However, if send-mail with OE manually (using free smtp server ie.: smtp.21cn.com) It is OK above testing: OE with same configuration: ie.: default account are same: the account setting with the smtp.21cn.com server the only different (I think) is one by socmapi.dll under Xbase++ application and the other one is type and send manually. anothe ref.: if the default account is setting using my ISP smtp server ....then both testing are send OK without problem...
