Send mail via smtp

Post by dododo01 »

Hi,
following a migration from VO to Xsharp,
I can no longer send mail via smtp.
I use an object (Class authSMTP) that inherits from CMailAbstrat.
After entering the DNS alias in the RemoteHost property, in VO I see the IP and in XSharp there is nothing.

Could you help me?

Code: Select all

-------------------------------------------------------------------------------------
	LOCAL oCeMail AS CeMail
	LOCAL oCSmtp  AS authSMTP
	LOCAL oDB     AS DBserver
	LOCAL aFile   AS ARRAY
	LOCAL aTab    AS ARRAY
	LOCAL jj      AS INT
	LOCAL ii      AS INT
	
	Default(@lAuth, FALSE)
	
	// création du mail
	pCopieInfo := iif(IsNil(pCopieInfo), {}, pCopieInfo)
	oCeMail := CeMail{}
	oCeMail:Subject            := pObjet
	oCeMail:MailBody           := pBody
	oCeMail:DestList           := pEmailTo
	oCeMail:CCList             := pCopieInfo
	oCeMail:FromAddress        := pEmailFrom
	aFile := {}
	FOR ii:=1 TO ALen(aPiecesJointes)
		AAdd(aFile, aPiecesJointes[ii])
	NEXT ii
	oCeMail:AttachmentFileList := aFile
	// fin de création du mail

	// connection au SMTP et envois du mail
	oCsmtp := authSMTP{oCeMail, "RSGB2 dll"}
	oCsmtp:RemoteHost := psmtp
	IF lAuth
		oCSmtp:UserName := pUser
		oCsmtp:PassWord := pPasswd
		oCsmtp:Authority := TRUE
	ELSE
		oCsmtp:Authority := FALSE
	ENDIF
	
	// envois
	IF !oCsmtp:SendMail( pPortSmtp )
		RETURN FALSE
	ENDIF

Hi Dominique,
to see what is going wrong here we need to see the authSMTP class code.

Hi

Thank you for your investigations.
We found a solution, we use the standard method SMTPSendMail
