Hi

I was used to send emails with Synapse, and below is an extract of my
code :

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i       Smtp
:= TSMTPSend.Create;    Smtp.TargetHost:= Inifile.ReadString (
'EMail', 'Server', '?');    if Smtp.TargetHost = '?' then      raise
Exception.Create('SMTP ERROR (TargetHost undefined in
'+Inifile.Filename+')' );    Smtp.Username:= Inifile.ReadString (
'EMail', 'Account', '');    Smtp.Password:= Decode_password(
Inifile.ReadString ( 'EMail', 'Password', ''));    Smtp.TargetPort :=
Inifile.ReadString ( 'EMail', 'Port', '465');    Smtp.autoTLS :=
Inifile.ReadBool ( 'EMail', 'AutoTLS', true);    Smtp.FullSSL :=
Inifile.ReadBool ( 'EMail', 'FullSSL', true );    if not Smtp.Login()
then      Raise Exception.Create ('SMTP ERROR (Login) : ' +
Smtp.ResultString );
Today, Smtp.Login returns FALSE and Smtp.ResultString shows :

Code: Text  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i * OK
[CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE LITERAL+
AUTH=PLAIN AUTH=LOGIN] Dovecot on host 112 ready
What does the message mean ?  Is Smtp no more supported ?

I have nearly the same with pop3send, but I can use Imap with ssl and
the same credentials to get emails.

I have read that we could send emails with imap moving messages in the
outbox folder.
But how can we set mailto and mailfrom ?

Thanks for help

What's the Value of Smtp.TargetPort AFTER Reading from the Ini-File?

It was a wrong value, and now I can login...

Many thanks !

No. You can clearly see in the message that it came from an IMAP
server, not an SMTP server. You connected to the wrong IP:port.

POP3, IMAP, SMTP - they are different protocols, and require different
components to access them properly.

Nope. IMAP is a mailbox management protocol. It can only manage the
content of mailboxes/folders, nothing more. It does not support
sending emails in any way. SMTP is the only official way to send
emails.

You don't, because sending emails is not part of IMAP, only SMTP.
