Email with SSL / TLS using FiveWin

[Jimmy]

hi,

i found CLASS TSmtp and CLASS TPop3.

Question : can they use SSL / TLS
if yes, how

what else can i use under FiveWin

---

i also use CDO but it also fail with TLS > 1.1
under HMG i use hbTIP but i was told to use hbCURL and OpenSSL instead.

Dear Jimmy,

> i found CLASS TSmtp and CLASS TPop3

Those classes don't support SSL / TLS

Please search for SSL in these forums

[Antonio Linares]

Please review this thread:

viewtopic.php?f=3&t=25962&start=0&hilit=mail+ssl

[Jimmy]

hi Antonio,

thx for Answer.

as i know Collaboration Data Objects (CDO) is not support any more since Server 2016
Server 2016 use Exchange Web Services (EWS) but it have no COM Interface.
not sure if CDO will work in Future

---

i do use hbTIP with SSL / TLS but i was told to change it
i need SSL / TLS > 1.1

so a can not use CLASS TSmtp and CLASS TPop3

i was told to use hbCURL but found no Sample for Email

---

under Windows 10/11 we have CURL.EXE

i have found Sample using Parameter to send Email using CURL.EXE

Question : is hbCURL and CURL.EXE "same"

Dear Jimmy,

> Question : is hbCURL and CURL.EXE "same"

Yes, they should offer the same functionality

> i have found Sample using Parameter to send Email using CURL.EXE

Please let us know it so we can find a way to use it with hbcurl, many thanks

viewtopic.php?f=6&t=40871&hilit=hbcurl&start=30#p248750

hi

thx for Answer.

i do not like to use "external" 3-PP Tool

---

have read in German Xbase++ Forum

Header-Eintrag "Message-ID:".
Den setzen wir auf eine UID mit angehängtem Domain-Namen, also so:

Message-ID: <821f7e56-8871-4657-ac3b-1504fbbd0456@mmorthosoft.de>

but i don´t know "where" to Set Message-ID

[elvira]

Could you please provide a smtp class that works with Gmail and ssl?

Thank you in advance!

[Jimmy]

hi,
