Is this not the same name of file you want to dump?

But as you said we can just make files "forward" to like (ux0:pspemu/psp/savegame/dump)
It will be faster and better method.

the actual file name stored differently in ux0
.
lets say it's ux0:email/messages /00/01.dat.02 ,and the file name in db is test.png
.
so when u click in the image the email app copy the file to a temp to ux0:temp/email/test.png (not 01.dat.02)
.
so the trick is when u rename the image in the db to ../../../test.png it will copy it to
ux0:temp/email/../../../test.png which means it will be in ux0:test.png
.
that's how it's working!

So i need to add trigger that renames files?
Like i have test.png and i want to dump it just renames it and i get it in ux0:test.png?

I think what mr.gas try to say is that when you click on "Forward" and the message edition panel opens, it takes some time to create a first temporary file inside "ux0:email/messages/00". Then, when you click on the attachment to see it, there is a secondary temporary file created inside "ux0:temp/email/blahblah/AttachmentName": it is this file which will be opened by the email application picture display functionality.
However, it is pointless to get this secondary temporary file if email application crashes because its copy takes too much time. So try to guess what path is represented by "../../.." will not bring anything. We must find out where is the first temporary file (inside "ux0:email/messages/00"), I think the file name probably depends on future message ID and attachment part index.

What I don't get from mr.gas hints (about saving the forward attachment path) is that, as long as the forward message isn't saved (and it cannot be saved if an attachment is too huge), nothing seems to be recorded in "mail.db". I already made this test a long time ago by dumping "mail.db" through music database trick while email application was open on "Forward" message editor. I will try to double check this when I have more time.

Yeah i finnaly find it

Everything is saving in "DT_MESSAGE_PART" in your mail.db

now im gonna try to dump some games

So first forward message then u will see in mail.db "ux0:email/message/00/00/53.Part.1.dat"

So just forward message, dump mail.db with music database trick, and then you just need to configure music.db and dump right file .. i can make tutorial if u want but later becouse i need to try dump something.

Only its little bit complicated becouse you need to count "parts"
you need to know that when you installing file like music.db "say its now 06.Part.2.dat" and after installing it will be "07.Part.1.dat
then when you click on forward for file you want dump it will be "07.Part.2.dat"
so you need to count everything before dumping... but maybe im wrong im now on forwarding stage xD
but anyway its like so "01.Part.1.dat" then "01.Part.2.dat" then "02.Part.1.dat" and so on...

just do a trigger to change the flag from 3 to 0 .. then close the email app .. so the email app wont delete the message and related files in the next boot .. get it ?
