Re: [twsocket] TSmtpCli in library: how to process events?

Re: [twsocket] TSmtpCli Questions
I am using a delphi 7 TRichedit box and using the code Smtpcli.MailMessage := editor.lines where editor is the Richedit. You need to set the PlainText property to false to read rich text into a stream or file, don't know about use of Lines.Text, not mentioned in the help. Use the debugger to ensure you are actually reading RichText. How do I set the Mime type for the TSmtpCli component. Using RichText for the main email body is not a good idea, since some email clients will be unable to interpret the RTF formatting. It is more common to use HTML for pretty formatted emails. So normally the main body is plain text, and HTML or RichText is an attachment, see the OverbyteIcsMailSnd and OverbyteIcsMailHtml demo projects. You can save your richtext to a file with RTF extension, and add the file name to the EmailFiles list, and the component should automatically set the content type and encode it. Unfortunately the file extension RTF is not currently recognised by the component, since it's virtually never used, so the source would need updating to set text/richtext.

Re: [twsocket] TSmtpCli Questions
1. I have a richedit box hat I have formatted text in Smtpcli.MailMessage := editor.lines; I have noticed that none of the formatting is carried across to the sent email How are you extracting the text from the richedit control, with which method? To maintain RTF formatting, you also need to set the MIME content type to text/richtext and encode it. 2. Is there a way to set a delivery report, in the email hearder, if so how? Delivery reports depend on the client recognising the special header and returning an email, many clients deliberately do not. Just set ConfirmReceipt to true, and the Disposition-Notification-To: header will be added with your from address.

Re: [twsocket] TsmtpCli with SSL
Does the TSmtpCli support ports other than 25? No, only TSslSmtpCli supports SSL/TLS. Including SSL/TLS connections or method/command STARTTLS on any port number you want. Just to clarify Arno's answer: If you need to send Emails with SMTP over SSL/TLS link, you need the SSL enabled version of the well known TSmtpCli component. This component is names TSslSmtpCli. The usage is almost the same as TSmtpCli with of course added properties, methods and events to handle SSL/TLS operation. TSslSmtpCli is included in the standard ICS distribution of ICS. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

At least Firebird provides 5 priorities so why should we remove this

It's likely that X-MSMail-Priority can be removed, however my OE v6

Remember, one thing is the header it sends, another is the headers it understands from incoming mail. Typically, mail client developers understand that they receive messages from many different clients. RFC #2156 defines only 3 levels for the Priority header: normal, urgent, and non-urgent. X-Priority on the other hand is typically treated as a numeric value (0 through 5), where zero (or no header) means normal and the rest is a range between very low and urgent. This was the way it was defined in the old Eudora client. Like I mentioned, it's a mess of standards. What most programs do is to use what they think is the most common (e.g., X-Priority) and then attempt to detect all other common possibilities. I think ICS should do the same, pick one from the most common ones and send that one only. Client applications using TPop3Cli component should then take care to expect different formats and attempt to decode them. It should not hurt to include more than one, but it may be unnecessary, and it also doesn't follow the convention of other popular clients. The RFC standard suggests Priority, but like I said, not many clients seem to be using it. They probably support it, though. The most common one seems to be X-Priority. I'm not an expert on this, so please do not think I'm proposing definitive solutions. These are mere personal suggestions based on my observations. Your views are welcome. Isn't it just the high priority itself, that scores? I did a bit more research on why SpamAssassin and why it would treat the priority headers as spam and found the following default rules: X_PRIORITY_HIGH: 2.0—Sent with 'X-Priority' set to high MISSING_MIMEOLE: 0.5—Message has X-MSMail-Priority, but no X-MimeOLE PRIORITY_NO_NAME: 0.5—Message has priority setting, but no X-Mailer It seems obvious what the problem was with the original ICS code: a very high spam score was given because X-Priority was set to high instead of to a numeric value, suggesting that it was a spamming tool and not one of the many real clients that use the Eudora header. Also, X-MSMail-Priority is expected to come with X-MimeOLE which identify the client as MS Outlook. And lastly, any priority header detected without an X-Mailer header suggests that it doesn't come from a real mailer. Also, keep in mind that modern clients use a single header for priority (whichever they pick), so including many may also alert other spam detectors. dZ. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

It actually uses 5 values, look at the source:

In scanning messages sent from MS Outlook through an MS Exchange Server, I
noticed that it set the following headers:
...
Importance: high
X-Priority: 1
...
This suggests that those two headers are deprecated. SpamAssassin (as
well as other anti-spam engines) tend to look for these obsolete headers as
markers of e-mail sent by a spamming tool.
The rationalization is that users tend to upgrade eventually to the
latest versions of applications, while spamming tools, being created ad hoc and
seldom maintained consistently, do not react as quickly to changes. Thus it is
reasonable to assume that if a spam tool is designed to mimic Outlook at some
time, whenever those headers are changed by Microsoft, only the tool will
continue using them.
I suggest a better solution would be as follows, which more closes
adheres to conventions. These values have been empirically discovered testing
with Apple Mail, MS Outlook, and Mozilla Thunderbird. They are also described
in various suggested standards. Notice that Normal Priority is typically
marked by the absence of any priority marker.

Sender ok RCPT TO:a...@msn.com 451 Too many messages Send failed RequestDone Rq=9 Error=451 Disconnect failed RequestDone Rq=6 Error=451 First, am I right in assuming this is a mail server issue? Correct. Or could there be something I can do with ICS other than just failing gracefully? The number of emails involved is actually quite modest (here the process failed after 25 emails had been sent). Are those messages just carbon copies or blind carbon copies? If so, you could try to issue Data when you get the 451 error, and send the next 25 after command Reset if the server does not drop the connection of course. Second, how can I avoid the Disconnect failed error as well? Where does it come from? Does the server disconnect the line? -- Arno Garrels -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

With a program sending multiple emails, one user is getting this:
MAIL FROM:x...@btconnect.com
250 x...@btconnect.com... Sender ok
RCPT TO:a...@msn.com
451 Too many messages
Send failed
RequestDone Rq=9 Error=451
Disconnect failed
RequestDone Rq=6 Error=451
Are those messages just carbon copies or blind carbon copies?
If so, you could try to issue Data when you get the 451 error,
and send the next 25 after command Reset if the server
does not drop the connection of course.
No, the emails aren't carbon copies, though the text might be identical.
Second, how can I avoid the Disconnect failed error as well?
Where does it come from? Does the server disconnect the line?
I am issuing a Quit() myself when the Mail() command fails. The log output
above is generated in the SmtpClientRequestDone event
switch (LastRequest)
{
case 8:
s = (Error == 0) ? Connected : Connect failed; break;
case 9:
s = (Error == 0) ? Mail sent : Send failed; break;
case 6:
s = (Error == 0) ? Disconnected : Disconnect failed; break;
}

Yes, it sounds as though I need to ask the user to talk to their service
provider. But 25 emails seems unbelievably stingy.

I have looked at this source and there is no OnRequestDone source, but I do see that this source uses a TSyncSmtpCli component and that SendButtonClick event source contains what looks to be a way to send multiple emails using SmtpClient.OpenSync; instead of SmtpClient.Open; So can I gather that I should be using a TSyncSmtpCli component (using the SendButtonClick event source as a guide) instead of the TSmtpCli component using some form of coding in the onRequestDone event?

Re: [twsocket] TSmtpCli - How do I process multipleemailsusingthiscomponent?
Mike, If you read my posting you will see how to implement the RequestDone event. It's also explained in the wiki at http://wiki.overbyte.be/wiki/index.php/TSmtpCli.OnRequestDone There is a line of code where you re-populate the fields (subject, recips et.c.) and this is where you would read from the database. At the wiki it's explained as generateSingleEmail; //a procedure i use to create my e-mail What happens after the mailserver has sent you that it has received data you check if you have any more mail to send and then do a mail from again. If not then you do a quit. I use the normal SmtpCli.

Hi Fredrick, Sorry, I have somehow skipped over your comment //generate email to send here, set all values et.c. when reading your prior post. I was not aware of the wiki although I probably should have been as I have looked at other links on the website. I will give this a go and see what happens.

Mike, If you read my posting you will see how to implement the RequestDone event. It's also explained in the wiki at http://wiki.overbyte.be/wiki/index.php/TSmtpCli.OnRequestDone There is a line of code where you re-populate the fields (subject, recips et.c.) and this is where you would read from the database. At the wiki it's explained as generateSingleEmail; //a procedure i use to create my e-mail What happens after the mailserver has sent you that it has received data you check if you have any more mail to send and then do a mail from again. If not then you do a quit. I use the normal SmtpCli.

Re: [twsocket] TSmtpCli Attach files without real files
I have not tried it but from looking at the sources I would say that it might work if you would change the OnAfterFileOpen event so that it passes the FStream as a var variable. Then you could initialize that stream variable with a memory- or stringstream in your event handler. Maybe you will have to do Base64-transcoding in your event handler also but there are routines for that in the MimeUtil unit. /Tobias Francois PIETTE wrote: Out of my mind without checking the source code: You may override the function which read the data frm file.

That won't work, since TSmtpCli does not convert strings to different charsets (something that still is to be implemented), currently it should work when sender and receiver use the same charactersets. Encoding is to make the component RFC-conform, since characters beyond 128 are not allowed in SMTP by default.
