sending email
in [Visual Basic]
|
From: kpg on 11 May 2010 11:01 Using MAPI I've been sending email in vb6 for years. But what it does is launch the clients desktop email program (outlook express, outlook, whatever). Many of my clients are now using web based email but want to email from my app. I found code that sends email using a gmail account using cdo for vb6, works great. So I try it with my cox mail account and I get: Sorry, You must login before using this server (or something like that). So I found tons of articles claiming they know how to solve this, using network credentials. Well, I've tried most and still I cannot authenticate with the smtp server. Note that outlook express has no trouble with this at all. I'm already passing the username and password to the smtp server, but this is not good enough. Apparently it must be done ion two steps, fine, but I can't get it to work. If I connect using outlook express, I can then send email, because, I assume, I am now authenticated (at least for a short time). So how does outlook express do this with servers that not only require authentication but require that you "first login". I'm always amazed at how the simplest things get so darn complicated. Anyone have a a link to samples that overcome this issue? Thanks, kpg

If the SMTP server requires credentials, you (or the user) are going to have to provide them. Provide a way in your app for the user to provide those credentials. Other than that, there's not much you can do. The other thing you can do is use an SMPT server that DOESN'T require logging in. Most likely, this WON'T be the user's SMTP server. You can use any SMTP server. It doesn't HAVE to be the user's. But in order to avoid providing credentials, it's probably one that you need to provide and it'd be open (meaning ANYONE could theoretically use it if they know about it). -- Mike
From: Mayayana on 11 May 2010 20:07 | No. I get the same error. | | Error 421: Sorry, You must login before using this server. 421 usually means "come back later". As far as I know it's sent in response to EHLO, which is the initial server connection. That happens before you get to the password part. http://email.about.com/cs/standards/a/smtp_error_code_2.htm You might try asking in the VBScript group, where a lot of people use CDO, and post the actual code. There may be something you can do. Another possibility -- I don't know whether this will help, but you might be able to debug the connection with it: http://www.jsware.net/jsware/scripts.php5#mailer It's an ActiveX EXE that comes with a sample script and an HTA. If you use debug settings to send mail with the EXE, the HTA will report the actual server conversation. Also, you might visit cox.net and find out exactly what settings you need to send email through them. But if you're not sending from your home machine that's connected through cox.net you may have a problem. They may be checking the IP addess to make sure it's one of theirs.
