No, I'm not saying that, you are.
I did run your test and I told you what the results were. I created a message with the title "Smart Mailbox Test" and sent it from my IMAP account. I also set up a Smart Mailbox with the rule of capturing messages in which the subject contains "Smart Mailbox Test." I then used the search function to locate all instances of this message. It located the message in the Smart Mailbox and it located the message in my POP Sent mail account. It did not locate the message in my IMAP Sent mail account which is the account I sent the message from.
If you remember my situation, I have a POP and an IMAP account for my email address. This is because I started with the POP and am trying to convert to the IMAP. During this conversion, this is when I realized that my sent messages from the IMAP account are not actually being sent to the server. I confirmed this by going to the server to look for them and they were not there. Luckily, the POP account does save them on my computer, but not in association with the IMAP account. This is why the Apple engineer and I set up the Smart Mailbox to capture all messages sent from my IMAP account. After they are collected in the Smart Mailbox, I manually drag them to the proper Sent Mail folder so that they will upload to the server.
In my case I use neither Yahoo nor Gmail. The one missing sent message that I became aware of was with a .mac.com IMAP account, so it has to be an Apple problem and I have reported it to them at http://www.apple.com/feedback/icloud.html
I checked the account thoroughly for the missing message both in Mail app and in iCloud, rebuilt mailboxes and then found this discussion where it became obvious it's a widespread problem.
In my case I've now unchecked 'store sent messages on server' but that won't suit people needing to access their email from different devices.
No, I'm not saying that, you are.
Apple say this:
A Smart Mailbox displays in one location messages that are stored in other mailboxes, so you don’t have to move messages between mailboxes. The messages displayed by a Smart Mailbox are based on criteria you define, and are automatically updated to include new messages that match your criteria. For example, you might create a Smart Mailbox that displays all messages found in all mailboxes from a specific sender.
But you still can't understand it.
Nothing you have written (except for the idea to use a smart mailbox) is correct, you are wasting the time of anyone looking for a solution with your Flat Earth approach.
According to the Apple engineer, it doesn't make any difference if I have both a POP and an IMAP account as they said all account operated iindependently. So, that won't make any test that I perform useless.
I really don't understand why you are so belligerent against anyone (not just me) that clearly points out that this is a Mac Mail issue. Your approach is uncalled for and destructive to the conversation, but you continue exhibiting this behavior with each new person that tries to speak. Please try to be nice to people, respect their comments, and stop telling them that they're comments and tests are useless because they don't support your own opinion.
Now, I'm out of the conversation myself. With the help of an Apple engineer, I found a workaround that works for me. I shared it with others so they can benefit and that was my only purpose in being here. I don't have time to continue being bashed by you for trying to help others. Good ridddance to you Csound1.
Oh ****, there is an open thread for this problem.
Only a few of my mails get lost after i sent them.
I run my own IMAP mail server (postfix and so on, works very well), checked all log files, the mail was delivered. But i can't locate this mail on my server, i searched all the files inside my mail folder directly on my server (all accounts).
Logs don't tell my anything negative.
This is a really really big problem.
I'm experiencing the same issues since beginning 2013, when I moved all my accounts from Outlook to Mail. I tried for months with my email providers (I have multiple account, even with domains), but unfortunately it seems there is no solution: "some" emails sent just are not saved.
There is no rule, and there is no way to find the reason why. Or, at least, I still did not find the solution.
I tried to read through all this post, but it seems to me there is no solution. Could someone please confirm there is no solution?
Are Apple engineers working on this?
Thank you all for your help
No they are not.
I called the support because I run my own server and i could see all traffic, logs and so on.
The answer from Apple: There is no bug/problem. BUT: They don't understand what I said, they can't understand the problem. I asked what the person @ the phone normaly works: English teacher...
So I got her boss on the phone. Finally he told me, I have to setup a fresh OSX install and test it.
Thats a big problem because this bug/problem only happens ever on 1/100 mails.
Unless it's not tested on a fresh installed system, they wont open a ticket.
I guess, the bug only appears after a wakeup (after time x, so Mail.app is not able to auto get new mails (IDLE is on...! Mail server sends(!!!) the notice to the system, but Mail.app doesn't do anything - i have to restart Mail.app EVERY time after sleep mode).
So... testing on a new system ok, but with the sleep/wake cycle it could take a lot of time, time i dont have and time i dont have to spend for such a big company.
What i have learned: Apple is great until there is no problem. But if there is a real problem on Apples side, there is also no problem.
If someone wants to call, this is my ticket for this problem: 450130140 (i guess it's written in german, but i'm not sure).
thank you very much for your email. I really do not believe. 1 out 100 is not a small problem for a mass software as it is Mail.app. I will switch back to Outlook, even if the integrations does not work well, it is better to be sure you find your email sent without becoming fool to do it...
If someone has a different experience please add to the forum
There goes another one out into the great wild blue yonder. Email sent and no copy placed in my sent folder. January 12, 2012 was my first post here and it seemed to quiet down a bit after that, as in, no emails lost. Now just recently it has started back up again. Maybe there are just too many bits flying around and a few must get lost here and there.
Here is an interesting story and in some way I think it applies: Years ago I had trouble with static on my phone line. I would call the phone company and they would fix it and then it would be fine for a few months or so. Then it would get bad all of a sudden again. I eventually found out from one of the repair men that there were a few "noisy" switches in the large bank of switches at the central station. As lines were added or moved around, my line would sometimes end up back on one of the "noisy" switches. He said he labled my line to remain where it was and it solved the problem for many years. Calls were so clear I could "hear a pin drop".
So in conclusion, I kind of think Apple has a few "noisy" switches there in the cloud and I seem to be back on one again. At least so it seems, as I am now losing sent emails with irregular frequency, just as I was back in Jan of 2012.
My fix - When it is really important and I want a copy of my sent email...I copy and paste it into the notes app. Once my email is sent and saved in the sent folder, I delete the copy in the note app. Pretty annoying but safe so far.
