Serverside function: Load eMails from Mailserver

[erich.wanker]

Hy ..

 

i want to download all 10 minutes emails from mailserver....

 

WHERE is the best way to store this function?

Is the TuniThreadTimer the right thing?

Where should i store the Timer?

 

 

 

 

i want to download mails.... save them on disk (subfolder /mails) .. create a database entry .. and if the user wants to see a mail - i use a tuniHTMLFrame for displaying it..

 

i store the html-Mails with filename "html_....html

i store the textmails with filename "text_....txt

i store the attachements with filename "Anhang_...[suffix of content]

 

if someone has a better idea - please let me know :-)

 

 

 

for the Maildownload i will use this old code i wrote with Delphi7 ;-) :

Why you work in unigui App? I have this

Unigui

.. Hi Gerhard...

 

you wrote:  "to view and write eMails...   you use UniGui .."

 

What do you use for display? .. UniHTMLframe???

 

Because i have problems if i show a Mail in a form containing a uniHTML-Frame ... the css of the emails chages the layout of my unigui-application ..

 

please have a look at: http://forums.unigui.com/index.php?/topic/8488-displaying-email%C2%B4s-changes-my-unidbgrid/

 

i solved the problem - but very crazy ;-)

 

 

 

 

P.S.:

 

now i use a service for downloading mails ... my Postng: http://www.delphipraxis.net/192647-email-downloader-service.html

 

do you know if somewhere ist a example-code, demo-code or something else online of a solution for:

 

pop without ssl

pop with ssl

imap

ect..

 

i just have the pop3 solution ..

 

Thanx for sugestions
