Sending Duplicate emails using Mail and mBox for mac

I have been sending duplicate emails inadvertantly recently. It seems it's when I use mBox for mac (registered copy) in Mail to use my Hotmail with IMAP.
I hadn't noticed it at first, but now I see everytime I send a mail I get 2 copies in my sent box. I can turn off the store sent messages on server option to fix it (but that's the whole point of having IMAP!!), or I can turn off mBox for mac and it also seems to work (but then I can't use IMAP!). I've also tried on the same machine from gmail, and iCloud accounts (MobileMe), and I had no issue at all. I've also tried 2 different Hotmail accounts, and both of them send double messages every time I send.
I've searched for a loooooong time, and can't find anyone with a similar issue - but surely I'm not the only one? I think anyone still using a hotmail account will eventually install something like mBox for mac if they've gone Mac recently - as I have.
I checked the mail headers of the 2 mails, and they are quite different (masked where appropriate) -

I'm surprised I can't find anyone else with a similar issue. I've submitted a support ticket with mBox/fluent factory, but I'm still not convinced it's their issue, and possibly a Mail on Mac issue.
Does anybody have any suggestions? Thanks for your help!

@ Kokola
Great staff!!! MBox Fluent Factory is very poor app.
I was having problem with duplicated sent emails and cleaning up my inbox, sent items and deleting emails. Try to contact them via email for over 3 months and never got a reply!
I just used the suggested configuration and my Entourage (email app for MAC) is working perfetcly. I can visualise all my online folders now!
Thank you so much!
mBox never addressed the issue and the duplicated emails reached new levels of annoyance but the good thing is that Hotmail and Outlook.com finally rolled out support for IMAP.
Incoming Mail Server: imap-mail.outlook.com
Outgoing Mail Server: smtp-mail.outlook.com
http://windows.microsoft.com/en-us/windows/outlook/send-receive-from-app
No more duplication issues once you switch over, and no need for a third party (mBox)software to bridge the missing feature gap.

Please send me some good links on System Function Calls

Hi,
I want to know more about System Function calls. Please send me some good links on the same.
Eg : CALL 'C_DIR_READ_NEXT'
 ID 'TYPE' FIELD file-type
 ID 'NAME' FIELD file-name
 ID 'LEN' FIELD file-len
 ID 'OWNER' FIELD file-owner
 ID 'MTIME' FIELD file-mtime
 ID 'MODE' FIELD file-mode
 ID 'ERRNO' FIELD file-errno
 ID 'ERRMSG' FIELD file-errmsg.
Rgds,
Raghavendra.

Hi,
CALL - Call a System Function:
Note
This statement is for internal use only.
It cannot be used in application programs.
As of Release 6.20, you should use Kernel Methods instead of system functions.
Syntax
CALL cfunc.
Addition:
... ID id1 FIELD f1 ... ID idn FIELD fn
Effect
Calls the system function cfunc. The relevant function must exist in the file sapactab.h. If you change or recreate a function, you have to compile and link the SAP kernel again. For this, you need the C source code files.
Normally, external programs should be called by RFC with CALL FUNCTION ... DESTINATION.
Addition
... ID id1 FIELD f1 ... ID idn FIELD fn
Effect
Passes fields to the called program by reference. With "ID id1", you specify the name of a formal parameter, and with "FIELD f1" the relevant field from the ABAP/4 program. If a formal parameter expects an internal table, the latter is passed in the form "FIELD tab[]".
Example
DATA RESULT(8).
CALL 'MULTIPLY' ID 'P1' FIELD '9999'
 ID 'P2' FIELD '9999'
 ID 'RES' FIELD RESULT.
Note
With some critical C functions, the system automatically performs an authorization check. If the user does not have the appropriate authorization, a runtime error occurs. You can check the authorization with the function module AUTHORITY_CHECK_C_FUNCTION.
Exceptions
Non-Catchable Exceptions
Cause: You do not have the authorization to call this C function.
Runtime Error: CALL_C_FUNCTION_NO_AUTHORITY
Cause: The system function specified is unknown.
Runtime Error: CALL_C_FUNCTION_NOT_FOUND
Cause: The system function SYSTEM is deactivated (in CALL 'SYSTEM')
Runtime Error: CALL_SYSTEM_DISABLED

After installing the new Yosemite OS on my iMac I can no longer send email. I can receive email, but not send. I use gmail and can send email on the gmail (google) site, but not on "mail" on my iMac. Any others with this problem? What should we do?

After installing the new Yosemite OS on my iMac I can no longer send email. I can receive email, but not send. I use gmail and can send email on the gmail (google) site, but not on "mail" on my iMac. Any others with this problem? What should we do?

My gmail, which is correctly configured for Mail with gmail SMTP and Google IMAP, works for awhile on Mail, which I leave open while working on other applications. But several times a day I get msg from Google: "We recently blocked a sign-in attempt to your Google Account" . . . and requiring me to verify my account details, re-enter passwords, confirm security settings (or change them from "disable" to "enable less secure methods" and so on). In Mail I also have tried "taking all accounts online", and re-entering my gmail password inside Mail account settings. These steps successfully re-set comms between gmail and Mail ... for awhile, then it happens again. Enough occurrences over a work day that I just quit Mail and revert to accessing gmail directly. Apple Care advisor and an Apple knowledge base article say that Apple can't deal with this, as gmail is third-party app, and they refer me to gmail, and so far I've found nothing helpful there.
From today I also have several instances of a window saying "Mail has unexpectedly closed" and asking me to Re-open it.
I also use Yahoo mail, which stops working with Mac Mail at the same time as gmail, but I do not receive notices to re-verify from Yahoo.
I recently upgraded from Mavericks to Yosemite. The Mail problem happened occasionally with Mavericks but is far more frequent with Yosemite.

Sending udp packets using java and receiving it using c

hi,
Is it possible to send udp packets using java and receive the same using c??????? if yes.... plz help immediately.

The biggest issue is data format. The JVM is big endian, with 16-bit characters. The machine running 'C' could be almost anything. A (signed!) byte array is probably the easiest unit of exchange.
The Java program has its own techniques for storing/retrieving data to/from the byte array - and the C program has its own techniques. ASCII Strings are often the easiest to exchange - just convert the java String objects to byte array and send them.
apaliwal1 has already given the UDP calls to send/receive the data.

I just used a firewire connection to transfer files from an older MAC to a newer MAC. My newer MAC has lost all that was on it, and all the applications are opening like they have never been used before and asking for Rosetta. Help!!!

I just used a firewire connection to transfer files from a PowerBook G4 to a MacBook Pro. The MacBook Pro has lost all that was on it, and all the applications are opening like they have never been used before and asking for Rosetta. How do I find all my files on the MacBook Pro, or undo what I have done???

IGNORE the last post: he thought you are using Lion or Mountain Lion.
Since you are using Snow Leopard, you need to install Rosetta. It can be found on your Snow Leopard Install DVD in the Options section.
Once installed all should be well again.
Also, if your computer is connected to the internet when the Dialog Box about PowerPC applications comes up, it MIGHT allow you to download Rosetta from the internet. There has been some discussion that Apple has discontined internet download of Rosetta into Snow Leopard.
Someone else will have to address your lost files problem.

HT204053 I had Snow Leopard and was using iWeb and Filezilla for my website (not MobileMe). Wanting to move to single-click publishing, I now find it is not supported by iCloud and Mountain Lion. I feel cheated, having bought it mainly for this purpose!

The other thing they don't tell you is that Mountain Lion disables OfficeMac, and I am considering uninstalling it for that reason - do I get my money back?!

You stated; "Mountain Lion disables OfficeMac"
That is not true.
Mountain Lion does not have Rosetta so it is not capable of executing PowerPC code. If you have MS Office 2004 that is coded in PowerPC code and will not run in Mountain Lion. What you need to do is upgrade to an Intel version of Office.

Adobe usually offers discounts on the full Creative Cloud (all apps) for customers with CS3 or later. However the Photography plan (Photoshop and LR) Is $9.99 pm (or local currency) and the initial benefits for CS customers who took what was then called The Photography Program (larger cloud storage) has now ended.

Want to use an external hard drive for my photos, iMovie, music and documents for use on my MacBookPro and iMac, can I do it and how?

I want to use an external hard drive to store my photos, imovie, music and documents, how can i do....Thanks

There are very good external drives available...I bought one when I got this MBP in September from OWC, http://www.macsales.com they are Mac specialists. Bought their 2 TB Mercury Elite Pro since it was eSATA, Firewire 800/400, and USB interface...use the Firewire 800 now. Partitioned into a 1.5 TB partition for Time Machine backups and 500 GB for extra storage. Both show up on the desktop, you just set the destination for you application to be the external drive volume you want to use.
If you want to discuss further, just ask what you want to know.

Like Norton Utilities for PCs, is it helpful to use a software on a MBP to clean up junk that is not used programs and documents?

Like Norton Utilities for PCs, is it helpful to use a software on a MBP to clean up junk, that is not used programs or documents? If so what's the best software for this?

No. See this recent thread and always look on right side bar for "More like this"
https://discussions.apple.com/thread/5098172?tstart=0
Norton for one thing does more harm than good and tries to modify the system's behavior.
Your post is not in the MacBook Pro area, would also be more along t he lines of something for OS X Mavericks Community.

Why use link-local addressing for HSRP in IPv6?

I have scoured the internet for an answer to this question, and am no closer to having it answered. Am hoping someone here can help!
* Why do we use link-local (or autoconfig) addresses for the standby IP in FHRPs? If you are forwarding a packet towards a link-local destination address, wouldn't the source address then have to be a link-local address from the same prefix, which according to scope, should not route beyond the local link? How do you route an IP packet that has a link-local address for a source address?
Any insight would be much appreciated.
Thank you in advance.

Dougles,
next hop is used for reaching "gateway" that know where to send packets farther (read it as "next hop to the destination")... routing in IPvX is hopping between nodes where every hop is closer to destination... This is theory behind.
So as machine that needs to send packet to "not directly connected destination" you only need to send packet to gateway leading to this destination...
so you need to send packet so, that "gateway" will recieve this packet and gateway then send this packet farther... it is not important what IP address this gateway has.
On ethernet you only need to know MAC address of this gateway and you send packet (with your source IPv6 address and intended destination IPv6 address) encapsulated with "destination MAC address" of gateway. When gateway recieve ethernet frame, and this frame is for it (destination MAC address is its MAC address), the gateway will proceed IP header (inside IP header the gateway see IT is not final destination for this packet, and gateway will route this packet).
So configuring IP address as next hop is just "hleper for simpler administration".. MAC address of gateway is important. In IPv4 address resolution protocol (ARP) is used to automaticly get MAC address of gateway if you configure next hop as IP address. In IPv6 there is neighbor discovery protocol(ND) used for this task.
conclusion: you can use link local address as nex hop address for addresses from any scope ... next hop is just next hop, it is not used just for the same scope communication.
And question is... if we need just information about MAC address of gateway, why to ask using global address?
We need to get MAC address... that is information important just "locally"... so to ask for local information, why not use link local address ?
HSRP is the same case... really just need MAC address to send packets correctly.

Send me some useful links and documents for PI 7.1?
