Re: Error download mail external pop
My guess is that your antivirus is holding the message and checking and hMailserver doesn't like that
What Antivirus do you have on that system?
Can you disable it for a few minutes and manually force an external account download
OR
can you log onto the webmail for that account and look at the oldest message that is not yet downloaded

Just 'cause I link to a page and say little else doesn't mean I am not being nice.

Re: Error download mail external pop
The root cause is hMailServer Error code HM5136
This Error occurs if an outside SMTP-Server contacted hMailserver to devliver a new Email.
hMailServer has established the connection (wihout any error at this time) and the Remote SMTP-Server goes ahead, sends the
SMTP "DATA" Command and finished it with the "." Command and disconnects from hMailServer (without any error).
However:
In this state the whole Email Information isnt allready saved to disk, its in a prestate condiditon and saved in a receivebuffer (a variable)
and needs to be processed before it can be saved to disk as *.eml file. Exactly at this moment, the function in charge parseData() is failing
on reading the Emaildata and crashes the entire hMailServer Process because the error isnt catched by a try catch block.
This is the Error causing function:
void SMTPConnection::ParseData(std::shared_ptr<ByteBuffer> pBuf) / File: SMTPConnection.cpp, Line: 871
See: https://github.com/hmailserver/hmailser ... n.cpp#L871
This is a bug and cannot be solved by a user, except if the user can filter out such Emails before it reaches the hMailServer
I think, the best way to solve this Type of Errors would be to change the above mentioned function code in a way that such maleformed
Emails can be securely dropped (which will prevent the server to crash). Finally a Logentry should be created so the Administrator
has a clue whats happend.
Problem:
*Hard to recreate the Error causing situation on a Developer Machine without the Error causing EML-File.
This Error occurs if an outside SMTP-Server contacted hMailserver to devliver a new Email.
hMailServer has established the connection (wihout any error at this time) and the Remote SMTP-Server goes ahead, sends the
SMTP "DATA" Command and finished it with the "." Command and disconnects from hMailServer (without any error).
However:
In this state the whole Email Information isnt allready saved to disk, its in a prestate condiditon and saved in a receivebuffer (a variable)
and needs to be processed before it can be saved to disk as *.eml file. Exactly at this moment, the function in charge parseData() is failing
on reading the Emaildata and crashes the entire hMailServer Process because the error isnt catched by a try catch block.

Re: Error download mail external pop
I have had the error once or twice myself over the years and there is no obvious cause for these random runaway iocp process errors. A restart of the service will suffice and things will continue normally.
Stopping spamassassin will not make any difference as that only gets involved when an email has been passed to it but in this case the email hasn't even arrived.

If the email contians a virus, the AV won't allow that virus to be written to disk - and I don't believe that this has anything to to do with hMailserver's built in virus scanning, but just how the AV behaves for the entire file system...

Thats unlikely because hMailServer doesnt save the variable to Disk a this point in time, it crashes before the code which saves the Emailcontent to the DATA Folder as *.eml file is executed.mattg wrote: I still think that the local machine AV is quarantining the .eml at this point in time as the Data Directory hasn't been excluded from AV scanning.

I have had a diffrent case in the last days with a Crashfump of hMailServer.exe (not mentioned in the Forum) which has allmost the same circumstances.
According to Debbuger Diagnostic Results, it points to the same Problemfumction.
Anyhow:
No AV Software or wrong read/write permissions should ever lead to a service crash. A known way to Crash hMailServer from the Internet can be exploitet and in a worst case scenario, an Attacker can gain access to the Localmachine Account
which has the highest permissions on a Windows Computer. Such an attacker could download maleware and takeover the complete Computer.
Such crashes are never unproblematic and should never be underestimated.
However:
Until we have more clarfication or a proof of concept exploit, it is best to run the hMailServer Service with less Permissions, atleast if hMailServer is running directly on the Internet and wothout using a Relayerver in gront of it.
I recommend the "Network Local Service" Windows account for now.

Once hmailserver crashes with the dump, it restarts automatically

Re: Error download mail external pop
The saveto *.eml file Function is called AFTER the ParseData Function but it crashes allready at the ParseData Function and never reaches the Saveto *.eml Function.As the .eml file is being written to disk
Thats true, but the new hMailServer gets a brand new Addressspace by the Windows Virtual Memory Manager which has nothing todo with the Addressspace of the previously crashed hMailServerOnce hmailserver crashes with the dump, it restarts automatically
Proccess.
Now it gets really complicated:
A Hacker (i mean real Hacker, not a Scriptkid) can craft a peace of Binary Machine Code, called Shellcode and place it into the Addressspace of the crashing hMailServer.exe Process and can invoke malicious commands with the privilleges of the Localmachine account, which has unfortentlly higher permissions as a Windows Administrator Account. Now the injected shellcode can start EXE Programs, BAT or VBS Commands, download and start downloaded Trojans ect. This type of bugs is called a Remote Code Execution Exploit (RCE) and is really nasty and a Systems Administrators worst Nightmare.
There are builtin Countermeasures in Windows for example the Data Execution Prevention (DEP) and
Address Space Layout Randomization (ASLR)
(stolen from the OpenBSD/LibreSSL Project) but this doesnt stop a real Hacker.
Re: Error download mail external pop
Error occour on download via pop3 external mailbox, HM don't delete old message and Always download it as new message and duplicate them. I manual deleted message in a webmail and no error in this moment. I think this occour after i update HM to 5.6.8, after i try to install 5.7.0 x64 artifact but the problem persist, i solved with procedure up descripted.
Re: Error download mail external pop
Yeah, the Function in question parseData exists in allmost the same form for SMTP/POP3 and IMAP.
Unfortently there is no hMailServer Hotfix avaiable for it. I will file it as a bug and maybe Martin will take care of it.

Re: Error download mail external pop
The Crashdump didnt provice much more Information then we allready know.
There are two things which are important:
1) A probaly malicious or malformed Email is arriving hMailServer and leads to the crash while hMailServer is trying to handle it
2) The unknown, problematic Email cannot be saved, regardles if hMailServer crashes or not
Solution (IMHO)
There is only one possible way to fix this kind of Problem:
Drop the entire thing and catch the unhandled Access Violation Exception by Programmcode
This will not save the Error causing Email in any shape or form. The only thing we can do, is to log the Error
in hMailServers log and continue the operation.
Its not the best solution, but right know i have no better idea solve this Problem.

Re: Error download mail external pop
I filed this as official bug on the hMailServer Github Issue page
See:

This will inform Martin the Core Developer of hMailServer, so any official response should take place at this page.

Re: Error download mail external pop
I expected this.
However:
Martin the Main-Developer of hMailServer responded to this Problem
See:
https://github.com/hmailserver/hmailserver/issues/276
He doesnt agree with me right now, that the recommended code changes would help, but iam pretty confident it would atleast prevents
hMailServer Installations (which facing this sort of Problem with Errorcode HM5136 involved) from crashing and providing a log entry which
explain that a Malformed Email arrived hMailServer and that it was dropped for security reasons.
Solution:
I will include this Patch in my 32-Bit and 64-Bit Long Term Service (LTS) realeases and file it as Pull request for hMailServer official, so its
up to Martin to Merge the Patch into the official version of hMailServer or not.
The Patched Installer can be downloaded here, if its ready (this can take a few days)

This doesnt solve anything because the code changes required to solve your Problem is currently in no version of hMailServer included.
Iam working on a patch, please wait until its avaible (within 1-2 Days)
And if you decide to use it, please report back if the Problem was rellay solved.

Hi,
Sorry, it took longer as expected.
My first idea getting this Problem solved wasnt sufficient and seems not a good idea in itself.
The only thing left is, to get to the bottom of this Problem and trying to fix it by sanitizing the inputbuffer
before a Error can happen. This is a tedious Job and will take some time, but i cannot say how long.
