I use MailKit and IMAP Client. There are no problems with GMail mails, but when I make the same request to another server, problems appear.
Even a simple Search with the criterion MailKit.Search.SearchQuery.NotSeen does not work. I have access to the mailbox and mails are read, but filters do not work.
The only working filter is MailKit.Search.SearchQuery.All. Also I cannot change flag from NotSeen to Seen using Inbox.AddFlags, it works only with GMail.
When I use Fetch method with MessageSummaryItems.BodyStructure it returns TextBody = null.
Does it work correctly only with GMail or I must fix some server settings?

According to the log, the reason that MailKit's Search(SearchQuery.Unseed) returns no results is because your IMAP server is returning 0 matches.
It turns out that some IMAP servers did not implement rfc4731 correctly. Namely, they do not treat RETURN () as equivalent to RETURN (ALL). MailKit 2.11.1 will be more explicit and use RETURN (ALL) to work around this issue.
I'm trying to connect to my Atlas mongodb database through pymongo. I make the connection and do a basic query just to count the documents and it times out.
I am able to run the same string on my personal linux (and managed to get it working from a clean Docker), but did not manage to get it working from my Mac that I use for work (and neither did my colleagues and I wasn't able to make it work in a clean Docker image either). If it matters I'm running pymongo 3.8, that I installed with pip install pymongo[tls]. I tried downgrading as well and tried also pip install pymongo[tls,srv].
Personal guesses: something to do with proxy/firewall blocking the connection maybe? I checked whether the port was open On the server I whitelisted the 0.0.0.0/0 so that shouldn't be the issue.
import pymongo
client = pymongo.MongoClient("mongodb+srv://whatever:yep#cluster0-xxxxx.mongodb.net/test?retryWrites=true")
client.test.matches.count_documents({}) # this blocks and then errors

I'm working with the ESP8266 wifi module programming it in LUA using NodeMCU. I was able to connect from an iPhone app to the TCP server created by the wifi module to send 3 floats. I parse the huge string into 3 strings and send them using uart to and Arduino. It works just fine but after about 10 inputs it crashes/freezes. I need the constant flow of data to keep coming but consistently and I'm unable to do it reliably.
I've printed after each line to keep track of what is actually happening and even after that i'm still not sure what is going on.
Code
`
print("11\n")
wifi.setmode(wifi.STATION)
print("22\n")
wifi.sta.config("WDTS03","Walker14!")
print("33\n")
elWiFi =(wifi.sta.getip())
if elWiFi ~= nil then
print(wifi.sta.getip())
end
print("44\n")
if srv~=nil then
print("444\n")
srv:close()
print("555 \n")
end
print("Create server \n")
srv=net.createServer(net.TCP)
print("1\n")
if srv ~= nil then
print("srv !=nil \n")
srv:listen(6969,function(conn)
print("listening \n")
if conn ~= nil then
print("incoming\n")
conn:on("receive",function(conn,numbers)
print("2\n")
print(#numbers)
print("chekcing for nil \n")
if numbers ~= nil then
print("3\n")
p = string.find(numbers, "x=")
print("4\n")
q = string.find(numbers, "&y")
print("5\n")
if p ~= nill then
print("6\n")
if q ~= nil then
print("7\n")
x = (string.sub(numbers,p+2, q-1))
print("x=" .. x)
end
end --p ~= nill
print("8\n")
p = string.find(numbers, "y=")
print("9\n")
q = string.find(numbers, "&z")
print("10\n")
if p ~= nill then

if q ~= nil then

It fails on the "conn:on" argument for "srv:listen" after a few times
Thanks for the help and sorry if formatting is messed up. First time
Too long for a comment, sorry.
PANIC: unprotected error in call to Lua API (attempt to call a nil value)
Hard to tell which value was nil/null. Create a Minimal, Complete, and Verifiable Example (MCVE) to reduce the amount of code one needs to analyze.
The following snippet will eventually lead to out-of-memory due to closed upvalues. Each of your callback functions should use its own copy of the passed socket instance rather referencing the one of a wrapping callback function. The third line should NOT re-use the conn variable but define one with a new name.
See https://stackoverflow.com/a/37379426/131929 for details.

Don't use those old 0.9.x binaries, they're outdated and contain lots of bugs. http://nodemcu.readthedocs.io/en/latest/en/#getting-started helps you get started with a new firmware.
JavaMail newbie here. I'm trying to figure out what's wrong with a Javamail client that's embeded in a very large system. Sorry I do not have a short, self-contained example, but I'm hoping that someone might be able to give me some tips on how to go about debugging this issue.
It's JavaMail 1.4.3 in Java 7, running on Windows 7. The email server is on a Linux box. The intent of the code is to read all emails in an inbox, delete and expunge them, do some work on the emails, pause for a while, then repeat, looping forever. The problem is that if there are already emails in the inbox when this program starts and the JavaMail client code executes, it does not retrieve them. However, if I send emails to the inbox once the code is running, it retrieves them just fine.
The code gets the inbox with Store.getFolder("INBOX"), opens it with Folder.open(Folder.READ_WRITE) and does a Folder.getMessages(). The getMessages() call always returns no messages when first starting up, but does return the messages sent after the program's been started.
I'm using Pine to verify that the inbox does or does not contains messages, but am not opening the messages in Pine, so they should still be new. And if I use Pine to look at the inbox after running this code, it still contains old messages that were sent before the program was launched, but not any that were sent to it while the program was running (they've been successfully read, deleted and expunged).
The code should also be reading messages that are already in the inbox when it starts. I set mail.debug=true and that output follows. Again, any tips for how to dig into this would be greatly appreciated. Thanks.

Your server is telling JavaMail that there are no messages in the Inbox ("0 EXISTS") when it first opens it, then a message appears ("1 EXISTS"), which your program processes, deletes, and expunges. That all looks perfectly normal.
If you think there are other messages in the Inbox, the server disagrees. Perhaps you have some messages cached in your Pine client? Perhaps you've set Pine up to work similarly to how most POP3 clients work - download messages from the server, cache them locally, and delete them from the server?
We are are setting a the IMAP flags using the Java Mail API. Is there is a way to look at these flags in Thunderbird or other client for debugging purposes?
You can learn enough of IMAP to use socat to try yourself. Here's a sample exchange, I've marked my input with >, and responses with <:
$ socat READLINE ssl:imap.gmail.com:993,verify=0,crlf
< * OK Gimap ready for requests from [ip]
> a LOGIN user#gmail.com password
< * CAPABILITY IMAP4rev1 UNSELECT IDLE NAMESPACE QUOTA ID XLIST CHILDREN X-GM-EXT-1 UIDPLUS COMPRESS=DEFLATE ENABLE MOVE CONDSTORE ESEARCH
< a OK user#gmail.com User authenticated (Success)
> a SELECT INBOX
< * FLAGS (\Answered \Flagged \Draft \Deleted \Seen $Forwarded)
< * OK [PERMANENTFLAGS (\Answered \Flagged \Draft \Deleted \Seen $Forwarded \*)] Flags permitted.

You will want to at least skim RFC 3501, so that you understand UIDs and message sequence numbers, and section 6.4.5 will tell you the various things you can ask for in a FETCH command, such as flags, envelope, etc.
Each command is preceded by an arbitrary tag. I've used just a in the examples. It's intended to allow pipelining of commands and responses, so that they can be matched up.
The LOGIN command is just the username and password, and SELECT INBOX chooses the mailbox for the following commands to use. FETCH takes a sequence list (in the example, I said messages with sequence numbers between 810 and 820, and a list of items to fetch, in this case, just the flags.
Get Trojitá, it shows e-mail flags by default. I have no idea how to configure other MUAs to do the same, but I suspect many of them can do this for you as well.
