[twsocket] Correct shutdown/abort procedure
Hi all I use TsmtpCli and TPop3Cli, and am not shutting these down correctly, and would like some advice on how to stop these components. Here's the problem. These components work reliably on a thread where there are many other such components, reading and writing user email. Each account on our system gets one of each. At any point, an account may be requested to stop. What is the correct way to say to these 2 components 'stop whatever you are doing, clean up and quit'? The thread that the components exist in continues to run. The problem I have is that sometimes after they've stopped, I get GPFs in the message pump that these used to exist in - sometimes immediately, sometimes after a delay of several minutes.

Re: [twsocket] Correct shutdown/abort procedure
Thanks for the tip Arno. I was calling abort, but then going on to free the components after the Abort. I'll add a delay, and a custom message as you advise.

In order to abort and stop them as fast as possible call Abort. Abort most likely will trigger other events, setting all event handlers to nil prevents this. Since an instance may not be freed from its own event handlers one has to PostThreadMessage() a custom message, and free the object when this message is handled.

[twsocket] I keep tripping the same POP3 Client Exception
Hi
In response to a 'Stat' command, TPOP3Cli sometimes raises this exception:
procedure TCustomPop3Cli.StartTransaction(
OpCode : String;
Params : String;
RqType : TPop3Request;
NextState : TPop3ProtocolState; { Next protocol state in case of success}
DoneTrans : TPop3NextProc); { What to do when done }
var
Cmd : String;
begin
if FProtocolState pop3Transaction then begin
FErrorMessage := '-ERR ' + OpCode + ' command invalid now';
Display(FErrorMessage);
raise Pop3Exception.Create(FErrorMessage);
end;
On the whole, things work OK, and this may be a timing issue, or I'm not
handling an error correctly.
How can I check it is safe to issue the Stat command?
Thanks

[twsocket] Problem sending larger attachments
Hi Any ideas how I solve or problem solve this? Using Thunderbird I can send 5MB+ emails to myself. Using TSMTPCli I can send something like 1.5MB, but nothing bigger. The SMTP server does not report any error - the email just does not arrive. Any ideas why this would be? The SMTP server is the same in both cases. I've whitelisted myself, and I don't think anything is being blocked by anti spam. It seems to be size that is the issue - I can predict which ones will arrive, and which not, based on size.

Re: [twsocket] Using lots of TSmtpCli in a single application
Thanks for all the messages! Some useful things for me to know. My question wasn't about email volume as such, but simply about having lots of TSmtpCli components active at any one time, even if they are not doing anything. The application I'm working on is 9 years old, has many thousands of man hours spent on it, and whilst it would be nice to have a single TSmtpCli, in order to avoid a massive code rewrite it's much easier for me to have lots of TSnmpCli components, rather than one (you can't see it, but I can of course). Reading the responses, it looks like this is somewhat un-orthodox but will not generate any stability problems at all with respect to ICS - which is what I'd hoped.

Re: [twsocket] Using lots of TSmtpCli in a single application
This is a really useful thing for me to know, thanks for posting this. This is the correct way of handling. As per the RFC, error codes win the 400 range are transient errors, meaning that they are temporary, and the sender should retry eventually; while codes in the 500 range are permanent errors. Of course, servers are not required to adhere to the RFC, but I haven't come across one that does not in this regard. It's for their own benefit, for they stand to break the entire system and lose e-mail if they send the wrong response. Greylisting and other anti-spam techniques should result in a 4.x.x error. Any mail sending application should be smart enough to re- queue these. 5.x.x errors must not be re-tried without modifications. In my mail queue server I have a simple algorithm to attempt to determine the reason for the failure, and sort them so that they can be manually analysed and corrected if necessary. The most common errors I've seen are: 1. User not found (account closed) 2. Destination server blacklisted in ORDB 3. Common typo in domain name (e.g. yaho.com, gmail.cmo, etc.) dZ. _ Windows Live Messenger: Happy 10-Year Anniversary—get free winks and emoticons. http://clk.atdmt.com/UKM/go/157562755/direct/01/ -- 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
[twsocket] Using lots of TSmtpCli in a single application
Hi I've used ICS components for a while now and had great results. I have something new to do and wanted some advice before starting a new project. Previously my app used a single TSmtpCli and this all worked fine. Now however I have to send mail on behalf of lots of accounts and the number of TsmtpCli components in use simultaneously, used in a multi threaded application, could be in excess of 100. Assuming that the machine has enough memory and processor power, am I likely to run into any problems? I don't evisage the email volumes being massive - say 20 per hour per account, meaning something like 200 per hour outgoing per application. My reason for asking is simple - I'm doing something unusual. If it is likely to be a problem I can try concentrating all emails through a single Tsmtpcli but because of the code base I am working with this will be much harder to do. Any comments welcome.

Re: [twsocket] I need some help understanding TWsocket states
Thank you to the two people who replied. I got really good advice which I followed and this seems to have given me a working server, but I still have client problems. - I created a message-pump in a distinct thread for the DLL server, as advised. - Both client and server were changed to async programming style, and this worked for the server. I have another problem though, which seems stange, and may be related to timing (or something). My client wants to sometimes connect to the server, send a few lines of data, and then disconnect. When I want to send data this is what I do procedure sendData(asMessage: string); begin mystringlist.add(asMessage); if mytwsocket.state wsConnected then begin mytwsocket.addr := '127.0.0.1'; // client and server are on same machine mytwsocket.port := '17072'; mytwsocket.connect(); end; end; Then I have handlers for OnSessionAvailable and OnDataSent. OnSessionAvailable doesn't seem to get called ever. In OnDataSent I do this begin if mystringlist.count 0 then begin mytwsocket.sendStr(mystringlist[0]+#$D#$A); mystringlist.delete(0); // we've sent this one end else begin mytwsocket.close(); // no more data to send, so close end; end; Here's what I've observed. The client can send once, and that's it. I can't send twice. However, if I put a breakpoint at the end of the function that connects to the server,it works - almost like there is some kind of timing issue. I'm working on Windows 2003. Should I use threads for my clients as well? Any advice is greatly received. Wilfried Mestdagh wrote: Hello Pete, if myclient.state wsConnected then begin myclient.connect; loop for 5 seconds begin You have to think async.

The client can connect to the server and successfully send as much data as it chooses. However, once it disconnects it can't reconnect. The code on the client is broadly thus (using a pseudo code): if myclient.state wsConnected then begin myclient.connect; loop for 5 seconds begin myclient.processMessages; if myclient.state = wsConnected then begin lbConnected := TRUE: break; end; end loop; end else lbConnected := TRUE; if lbConnected then myclient.sendstr(thedatastring); myclient.close(); On the server, this is what I have: myserver.OnsessionAvailable begin myserversocket.dup(myserversocket.accept()); end; I'm also handling the OnDataAvailable event, and this works fine - but only the first time (or at least until the client disconnects). I've tried recalling listen() in the OnSessionClosed event, but it does nothing. The state of the client on the 2nd attempt to reconnect remains at closed.

[twsocket] [tsyncsmtpcli] Problem sending email to Exchange 2000 server
Hi (Before saying this is a server problem, read the whole message, as it's got us confused) Our ICS-based email app (using TSnycSMTPCli) work fine most of the time. We have once instance though where when sending external emails (i.e., emails that require to be sent over the internet, not internally) the application using ICS thinks it's sent, but the email just disappears. Internal emails go fine. Now, the strange thing is that Outlook Express (connected as a SMTP/POP3 client) on the same machine as ICS *can* send external emails with no problem. Does anyone have any ideas as to why OE might be able to send, and TSyncSMTPCli might not? There are no errors reported by ICS. If anyone can help I'd be grateful.

Re: [twsocket] [tsyncsmtpcli] Problem sending email to Exchange2000 server
Wow thanks for your quick reply. I'll reply between the lines. First, what kind of SMTP Server is receiving the e-mails on the other end? Exchange 2000 server. Second, are you positive that your ICS application is sending a QUIT command at the end of the transaction? I believe so. The function QuitSync is called, and the return code tested. And third, the server might be rejecting messages from your ICS client because it does not recognize the MUA as a valid one, while it recognizes OE as a legitimate mailer. That's an interesting one. What is MUA and how do I set it? Sorry for what is probably a dumb question.

Second, are you positive that your ICS application is sending a QUIT command at the end of the transaction? Some servers require this in order to queue a message, and if the connection is closed without receiving the QUIT command, they might dismiss the message. And third, the server might be rejecting messages from your ICS client because it does not recognize the MUA as a valid one, while it recognizes OE as a legitimate mailer. Can you post, or send by private message, a verbose log of a complete SMTP transaction between your ICS client and the server, from one of those messages that is lost? Also, you might want to compare the headers sent by your ICS client and those sent by OE. Try mimicking OE by forging the message's headers to look like Outlook Express' and see if that helps. dZ.

Re: [twsocket] [tsyncsmtpcli] Problem sending email to Exchange2000server
Hi Verify that OE use SMTP and don't use IMAP4. It definately uses SMTP.

Re: [twsocket] [tsyncsmtpcli] Problem sending email to Exchange2000server
Hi Are you absolutely sure? We get customers emailing us all the time saying Outlook works fine We get that too from our customers. Outlook Express and Outlook are quite different. We are using OE as the tester. Exchange is a beast with way to many stupid settings. I'll second that! Maybe Outlook is using one type of authentication while your SMTP client is using a less secure method (or no authentication at all). Our client is not using SMTP authentication, but neither is OE. I'm going to give SocketSpy a try to see what could be up. Thanks to everyone for their help.

It definately uses SMTP. Are you absolutely sure? We get customers emailing us all the time saying Outlook works fine, but your [SMTP based program] won't send emails outside of our domain! It's always that Outlook is connecting to the server using IMAP and the settings on the server are set to allow those emails to relay or whatever. I would double- and triple-check the settings on Exchange to make sure that emails coming in over SMTP can send out to the internet. Exchange is a beast with way to many stupid settings. The only other thing I can think of still has to do with the server side: see if there's some settings in Exchange that limit who can relay emails based on what type of authentication they use to access the server. Maybe Outlook is using one type of authentication while your SMTP client is using a less secure method (or no authentication at all).

Re: [twsocket] [tsyncsmtpcli] Problem sending email toExchange2000server
Hi No, it is *not* using IMAP4 - it's Outlook Express (not Outlook) we're using. They have the same name but are quite different. However, we will get a non-MS email client like pheonix tried out tomorrow. I'll post on my findings.
