PDF Attachments getting corrupted

[sri_elgora]

Hello,

I have a sporadic issue with hMailserver when receiving mails with PDF Attachments, the file is corrupted.

Example:
I'm sending an internal email (no other mailservers involved)
In the EML-File I can see the attachment is split into two parts
The IMAP-Client only receives the first part of the attachment.
We have Outlook 2021 and RoundCubeMail 1.6.8.
The attachment is corrupted in both clients.
hMailserver version is 5.7.0-B2643.17
Possibly the issue came with the upgrade from 5.6.8 to 5.7.0 (I upgraded because of the iOS Mail bug)

Here is an example snippet of the EML-File
Please notice the unusual signs at the end of the first part.
When I copy both parts together manually, I get the complete file.

I can send the original EML-File if someone is interested, please send a DM

I found more tmp files in the data folder, since the exact date of the upgrade:

[RvdH]

Don't know what you have been doing, but you can't simply upgrade from 5.6.8 (32-bit) to 5.7.0 (64-bit) without changings some things in your setup, like program and data and temp paths in hMailServer.ini

I doubt 64-bit hmailserver is installed in C:\Program Files (x86)\hMailServer, not? As it should be in C:\Program Files\hMailServer
Same with Data and Temp Paths, C:\Program Files (x86)\hMailServer\Data vs C:\Program Files\hMailServer\Data and C:\Program Files (x86)\hMailServer\Temp vs C:\Program Files\hMailServer\Temp

You probably made a mess, resulting in those 'Access is denied' errors

[sri_elgora]

I installed 5.7.0 with the installer, which checks for a previous installation and of cource it found one in C:\Program Files (x86), I didn't change it.
Then I copied over the latest binaries.

I will uninstall and reinstall in the correct location and move Data and Temp path to a location outside of Program Files.

Thanks for your time, I will give an update later.

[infohmail]

(5.7, 64bit, latest release). Sometime it's happens to me, but very rare. In our case I think it's linked to spamassasin (run on same hm machine) that doesn't complete the check in a timely fashion and this leave a .eml.tmp in \data folder. We don't care, because the email is still delivered (correctly) to the internal recipient.

[sri_elgora]

I uninstalled and installed hMailserver last night and have the same issues this morning:
Program Files are in C:\Program Files\hMailserver
Data, Events, Log Temp are in C:\hMailserver

Seems to me that another process is locking the file.
I will deactivate SpamAssassin and see if that helps, thanks for the hint.
