Well, now I got stuck again...
I did all of my code testing on Windows because that is my normal environment.
When all was done I had created a mailsupport unit encapsulating the stuff I
need for my emailings and I used that in a command line mailer to verify that
everything worked OK.
Which it did on Windows except for some fussy mailservers who would not receive
the emails (my GMail account), but the email was in any case sent.
But then when I moved to Linux (on Raspberry Pi3) I always got errors on mail
send. So no outgoing email.
So I have now finally traced the execution using the Lazarus debugger and it
seems like Synapse does not connect using SSL after all.. :(
I have set it up as well as I have understood the documentation with the smtp
switches for SSL and TLS active (set to true) and the port and user is set as on
Windows (after all I copied the source files over to the Linux box and opened
the project in Lazarus over there). The test emailer has all of the logon etc
info built into the executable (just for testing of course) but failed.
So when I single-step in the code I reach the following location after starting
on SMTP.Connect:
function TSMTPSend.Connect: Boolean;
begin
FSock.CloseSocket;
FSock.Bind(FIPInterface, cAnyPort);
if FSock.LastError = 0 then
FSock.Connect(FTargetHost, FTargetPort);
if FSock.LastError = 0 then
if FFullSSL then
FSock.SSLDoConnect; //<= I get to here
Result := FSock.LastError = 0;
end;
procedure TTCPBlockSocket.SSLDoConnect;
begin
ResetLastError;
if not FSSL.Connect then //<=This goes to no action
FLastError := WSASYSNOTREADY;
ExceptCheck;
end;
function TCustomSSL.Connect: boolean; //<= To here!
begin
ReturnError;
Result := False;
end;
Then I traced over into the ExceptCheck function:
procedure TBlockSocket.ExceptCheck;
var
e: ESynapseError;
begin
FLastErrorDesc := GetErrorDescEx; // <== HERE
if (LastError <> 0) and (LastError <> WSAEINPROGRESS)
and (LastError <> WSAEWOULDBLOCK) then
begin
DoStatus(HR_Error, IntToStr(FLastError) + ',' + FLastErrorDesc);
if FRaiseExcept then
begin
e := ESynapseError.Create(Format('Synapse TCP/IP Socket error %d: %s',
[FLastError, FLastErrorDesc]));
e.ErrorCode := FLastError;
e.ErrorMessage := FLastErrorDesc;
raise e;
end;
end;
end;
FLastErrorDesc gets set to "SSL/TLS support is not compiled"
So now I do not know what to do, is this indicating that I need to change some
Synapse config to get it working or is it a platform problem (Linux)???
What could I do in order to make SSL/TLS support "compiled"
In the documentation
http://www.ararat.cz/synapse/doku.php/public:howto:sslplugin
they write:
First you must explicitly select what plugin you wish to use. You can do it
simply by adding unit with SSL plugin to your project sources. You can add only
one from SSL plugins in one project! When you wish to use OpenSSL, then add
/ssl_openssl/ to your project uses, for example.
And that is what I have done, it is listed in uses of my mailsupport source file
as:
uses
Classes,
SysUtils,
smtpsend,
ssl_openssl, //<= Here
synautil,
mimemess,
mimepart;
Yet it is "not compiled"...
Very confusing.

Synapse's MimePart just get RFC2822 raw plaintext and decompose it into tree object structure representing MIME parts. And/or compose it back to plaintext. But where you got mail raw plaintext? SMTP, IMAP4, POP3, database, file,... (you can use it for HTTP forms too!) So, SMTP is just one of many options. MIME is independent. SMTP deliver messages by SMTP envelope, it ignoring message headers. Look at for any raw message from this conference. You are not written as recepient in "To" header, however you got it. You have been written as recepient in SMTP envelope only, not in message text.

Yes it really looks like the SendToRaw, SendToEx and SendTo functions at the

Yes I did but it involved calling the SendToRaw function inside Synapse at the

Thanks! Much obliged!
Seems like FSMTP is a globally available object managed somewhere else...
And that is where the SSL handling is defined too.
So it is set up to send a lot of emails.
In my case the mail sending is done in the end of the life of a task execution
thread so it will not live on further.
Slowly wrapping my head around Synapse, never used it before. I have used Indy
on Delphi since 20 years or so and continued that path on FreePascal/Lazarus.
But it does not handle openssl above 1.0.2 :(

//If you successfully pass authorization to the remote server
If Not FSMTP.AuthDone Then

Not so simple when you read scores of Internet pages on the subject...
Maybe I am reading an old version (from 2012) of your document lazmail-en.pdf?
The example I have found for the attachments handling uses a call to SendToRaw
inside Synapse where I cannot get at the SSL handling (without changing the
Synapse package code).
Here is where I am at now trying to make a function to send email with a
plaintext message plus at least one file attachment.
I started with the simple example from the wiki page and next I need to expand
it with code from the pdf regarding the attachments (once tyhe plain text
function works):
(***
* This function is based on the examples in:
* https://wiki.freepascal.org/Synapse#Sending_email
* and
* https://www.freepascal.org/~michael/articles/lazmail/lazmail-en.pdf
)
function SendSSLMail(const Subject, MailTo, MailFrom: string; Body, Attachments:
TStrings): boolean;
var
SMTP: TSMTPSend;
begin
SMTP:=TSMTPSend.Create;
try
SMTP.UserName := FSmtpUser;
SMTP.Password := FSmtpPasswd;
SMTP.TargetHost:= FSmtpHost;
SMTP.TargetPort := FSmtpPort; //465
SMTP.AutoTLS := true;
SMTP.FullSSL:=true;
if SMTP.Login then
begin
//What is happening here? 3 SMTP calls in a boolean expression?
Result:=SMTP.MailFrom(MailFrom, Length(Body.Text)) and
SMTP.MailTo(MailTo) and
SMTP.MailData(Body);
SMTP.Logout;
end;
finally
SMTP.Free;
end;
end;
Where is the actual sending of the email happening?
And how do I add the attachments?

It is very strange to me.
So a working SSL SMTP sending example (with file attachments)would help a lot
because my mail server demands such validation to allow sending.
You don't need to change Synapse ?
My setup is basically:
FSMTP.TargetHost:=MailCfg.HostName;
FSMTP.TargetPort:=IntToStr(MailCfg.Port);
FSMTP.AutoTLS:=MailCfg.UseTLS;
FSMTP.FullSSL:=MailCfg.FullSSL;
FSMTP.Username:=MailCfg.SMTPUserName;
FSMTP.Password:=MailCfg.SMTPPassword;
You need these properties:
{:If is set to true, then upgrade to SSL/TLS mode if remote server support
it.}
property AutoTLS: Boolean read FAutoTLS Write FAutoTLS;
{:SSL/TLS mode is used from first contact to server. Servers with full
SSL/TLS mode usualy using non-standard TCP port!}
property FullSSL: Boolean read FFullSSL Write FFullSSL;
That's it. From your story, it seems you just need to set
FSMTP.TargetPort:=465;
FSMTP.FullSSL:=True;

For some reason, sendmail has fallen out of favor, (likely because of it's conceived difficult setup), and most linux distros now use postfix, which in my opinion isn't any easier to configure, but it does allow for a wider range of options. If you check your linux boxes, you'll probably see postfix as the mta, and it can indeed be called to transfer mail from programs. I don't have any examples of this, but the documentation says it can be done.

Yes, because you were using the wrong package. If you use the correct package (laz_synapse.lpk), there will be no issue. See e.g. here: https://sourceforge.net/p/synalist/code/HEAD/tree/trunk/ But you can install it using the Online package manager. In the online package manager, DO NOT use the pl_synapsevs package. You myst use the laz_synapse (Synapse 40.1) package. It does not have GUI dependencies. I use it myself in a headless FPC-created server running on linux, since many many years, and use it in a Delphi-created server also running on linux, so I'm very confident it works as described :-) Michael. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

And this application is precisely the one I am working on now (after having replaced the LazSerial and SynSerial etc packages with a serial class I wrote myself using the FPC built-in serial unit. And using Indy10 for the networking parts since I have used that for some 20 years or so. So only if the emailing synapse is guaranteed GUI-free can I use it. I may even use some external program for mailing by using TProcess to run it But what? THere used to be something called sendmail or similar in Linux but right now I cannot see it on my boxes. And I am uncertain if it can do SSL logins and accept attachment files. Anyway, I received a reply from Remy L concerning Indy and that there is a fix for the oipenssl version available, which he has not tested. I will try to do that test in the near future. It would (if working) require no extra coding in my application just an update of Indy10 itself. :) -- Bo Berglund Developer in Sweden ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

I have an application which is ported from Delphi to FreePascal and will be used on Raspberry Pi (Debian based Linux). It uses Indy10 components. Indy is installed using OnLinePackageManager in Lazarus. The problem I have is that when I run the application it gets an exception when trying to send an email via an SSL encrypted SMTP mail server.
