PB.Ex Mail (Windows)

[Little_man]

RSBasic,

A strange error occurs when updating to "PB.Ex Mail 1.1.5.0" in Windows 10 Home, x64.
After putting back "PB.Ex_Mail_x64.dll 1.1.3.0" the strange error has disappeared !!...

Kind regards

Hello
Sorry for the late reply.
What error occurs?

[RSBasic]

PB.Ex Mail 1.1.6.0 has been released.

Changelog:

• Updated: .NET Framework 4.5.2 > .NET Framework 4.8 (required for TLS 1.3)
• Added: TLS 1.3 support

Please, is it possible to have TLS protocol 1.3 ?

Done, I added TLS 1.3 support.

I cant access my mails on my GMX mailbox... (SSPI call error is returned... ?)

I can confirm it with my GMX account (also with TLS 1.3) but I have no solution.
The following exception occurs:

A call to SSPI failed, see inner exception:
System.ComponentModel.Win32Exception (0x80004005): The function requested not supported
bei System.Net.Security.SslState.StartSendAuthResetSignal(ProtocolToken message, AsyncProtocolRequest asyncRequest, Exception exception)

Void StartSendAuthResetSignal(System.Net.Security.ProtocolToken, System.Net.AsyncProtocolRequest, System.Exception)

If I run my class library in Windows Forms it works without SSPI errors, but in PureBasic I get the SSPI error. I don't know.
Anyone an idea?

The DLL works fine with other mailbox... Thanks !!

Which provider does it work?

[drgolf]

Hello,

Very thanx for the update.
The DLL work with IKMAIL (infomaniak) but dont work anymore with Orange or GMX.
TLS 1.3 dont work too, but IKMAIL continue working.

I have message : Error: Échec d'un appel à SSPI, consultez l'exception interne on GMX...

The DLL work in june but in july no.

I have used Libcurl and IMAP for access mail box.

Maybe a parameter missing ?

[RSBasic]

Maybe a parameter missing ?

All required data will be sent.

The DLL work in june but in july no.

That is very strange. Maybe there was a certificate change.

I tested with the following mail providers:

• GMX (belongs to IONOS)
• Web.de (belongs to IONOS)
• Orange.fr
• Strato (belongs to IONOS)
• IONOS
• T-Online
• Hotmail
• Google Mail
• Hosting.de
• Outlook
• Mail.de
• Yahoo
• Freenet
• AOL
• Vodafone
• 1blu
• emailn.de
• Mailbox

Somebody tell me that in place using :

Code: Select all

client.Connect(host,port,false);

use :

Code: Select all

client.Connect(host,port,SecureSocketOptions.None);

Maybe this help.

Hi everybody,
I'm trying to find the root cause of the extreme slowness when retrieving Gmail mails (14 seconds for each mail). 65 mails with only some text in the subject / title (50 chars).
Using this excellent lib since 2019, no problems since last days.

I've updated to last version (1.1.6.0 Pb Ex Mail, before 1.1.3.0), using PB 6.02 x64 under Windows 10 X64, same problems. Using TLS 1.3, with SSL enabled : Are these rights parameters for gmail mailbox ? However, Mails are well retrieved, but with slowness.

When looking a little bit further, the following command :

Code: Select all

ExamineMailEx(1, #PBEx_Mail_SeenType_AllMails, #PBEx_Mail_FetchType_AllData, 0, @ErrorOutput$)

takes 14 seconds to execute (before maybe 2 or 3 seconds).

I tried the

Code: Select all

#PBEx_Mail_FetchType_OnlyHeaderData 

flag instead of

Code: Select all

#PBEx_Mail_FetchType_AllData

, a little bit better (from 14 to 7 seconds)...

The command used to open mailbox is :

Code: Select all

OpenMailEx(1, #PBEx_Mail_Protocol_IMAP, imap_server_name$, Val(imap_server_port$), imap_userid$, imap_password$, Val(ssl$),#PBEx_Mail_ProtocolVersion_TLS13, @ErrorOutput$)

Do you have any idea ? Already encountered this case ?

Thanks a lot in advance !

Hello GG

I tested with my Google account. I have 260 emails in my inbox.

For each email with #PBEx_Mail_FetchType_OnlyHeaderData and without get attachments: 500-600 milliseconds
For each email with #PBEx_Mail_FetchType_AllData and without get attachments: 600-700 milliseconds
For each email with #PBEx_Mail_FetchType_OnlyHeaderData and with get attachments: 800-900 milliseconds
For each email with #PBEx_Mail_FetchType_AllData and with get attachments: 900-1000 milliseconds

I have no idea why it's slow for you.

My test code:

Code: Select all

;...
If ExamineMailEx(1, #PBEx_Mail_SeenType_AllMails, #PBEx_Mail_FetchType_OnlyHeaderData, 0, @ErrorOutput$)
    While NextMailEntryEx(1, @ErrorOutput$)
      MailEntrySubjectEx(1, @Output$, @ErrorOutput$)
      Debug "Subject: " + Output$
      MailEntryFromEx(1, @Output$, @ErrorOutput$)
      Debug "From: " + Output$
      MailEntryToEx(1, @Output$, @ErrorOutput$)
      Debug "To: " + Output$
      Debug "Date: " + FormatDate("%dd.%mm.%yyyy %hh:%ii:%ss", MailEntryDateEx(1, @ErrorOutput$))
      Debug MailIDEx(1, @ErrorOutput$)
      
;       Debug Str(CountMailAttachmentsEx(1, @ErrorOutput$)) + " attachment(s)"
;       If ExamineMailAttachmentsEx(1, @ErrorOutput$)
;         While NextMailEntryAttachmentsEx(1, @ErrorOutput$)
;           If MailEntryAttachmentsFileNameEx(1, @Output$, @ErrorOutput$)
;             Debug Output$
;           EndIf
;         Wend
;       EndIf
      
      Debug ElapsedMilliseconds() - StartTime
      StartTime.q = ElapsedMilliseconds()
      
      Debug "--------------------------------------------------"
    Wend
   
  EndIf
;...

Hello RSBasic,

Things are getting better, I retrieved "normal" timings, I suppose it came from Google, no changes from my part.
Thanks again for your lib and support.

[BarryG]

Tried this code again to read my Gmail Inbox (using IMAP) and it connects, but nothing is output. That is, none of the code between "While NextMailEntryEx(1, @PBEx_Mail_ErrorOutput$)" and "Wend" is executed, so I don't get the Debug output of "Subject" etc. Any ideas?

Hi and a Happy 2024,

Going to sound like a silly question, but when using :

Result = SendMailEx(ID, Subject$, Body$, Priority, From$, ToAddress$, CC$, BCC$, Attachments$, @ErrorOutput$)

How do format the text for the Body$ ?

I thought using #crlf$ would insert linebreaks but it doesn't.

Any help appreciated.

Cheers

Hello captain_skank

HTML code is used by default. I.e. if you want to insert line breaks: <br>

Sorry for the delay in replying, works like a charm.

Thanks muchly.

Yes, you'll need to create an app password for your application in Gmail. Then you can use it in PureBasic: https://support.google.com/mail/answer/185833?hl=en
