Following is a recordio session of one smtp session where there are 3
rcpt to. 2 are bogus, 1 is real. Message is spam.


I'm not sure that it's chkuser that is getting in the way; I tested the 
old version (chkusr 1.0) and it works correctly.


The error you pasted:
 451 See http://pobox.com/~djb/docs/smtplf.html

implies that it's not the fault of chkuser at all; that the message is 
simply badly formatted and would have been rejected to a single good 
recipient as well.


To accept these types of badly formatted messages, use fixcrio (which 
you'll have to check if your TLS patch patched).

Re: [vchkpw] Re: chkuser - rejects legit mail, when followed by bad e-mail

2010-10-08 Thread U. George 
It is not clear to me if the same message is sent to multiple users, or 
multiple messages to multiple users using the same smtp session.


BUT, I think, if the *last* email rcpt is legit, then the message is 
passed along to that legit account irrespective of any any failures that 
happened before. I will have to review the mail log to see if thats true.


I will have to log the smtpd session to see what the actual conditions are.

If I understand this correctly, I think this is the nature of the beast.
If you send an email to multiple addresses at the same server/domain,
some of which are good, and others which are not, the smtp protocol only
allows for rejection or acceptance of the entire message, somewhat
unfortunately. Qmail remedies the situation by sending messages
individually, but this doesn't solve the problem of other servers
sending a mix of valid and invalid addresses in the same message.

Also, addresses are processed by chkuser in whatever order the sending
server provides them. Sequence is of no significance.

the first e-mail rcpt is legit.
It appears that if more rcpts follow, and those accounts dont exist,
then the first legit e-mail is not processed, as is rejected with all
the other bogus attempts to send e-mail the domain.

The chkuser test process appears to try a fake e-mail, and then a
legit e-mail. BUt does not try a legit e-mail, and then a fake e-mail.
