Original GitHub issue: https://github.com/modoboa/modoboa/issues/546

In the webmail, create a new message, then attach a file. If the file size is 1MB or greater, after clicking on the "attach" button, the "Send" action is running indefinitely. If the file is smaller, then the attachment is working as expected.

Tested with files created like that:

dd if=/dev/zero of=emptyfile-1023.dat  bs=1024  count=1023
dd if=/dev/zero of=emptyfile-1024.dat  bs=1024  count=1024

With a file up to 1023 bytes, like emptyfile-1023.dat : attach file is OK.
With a 1024 bytes file, like emptyfile-1024.dat : attach file is OK.

Backtrace:

Internal Server Error: /accounts/logout/

What is your maximum attachment size ? (see Modoboa > Parameters > Webmail)

10Mo, so the limit is not reached.

If the max attachment size is reached: is there an error message clearly displayed to the user ? (It should).

Your stacktrace is strange because it looks like the one you pasted for #548

Are you sure it is the good one?

And what about nginx? It seems you receive a 413 error...

As you advised me limit has to be configured in modoboa AND in nginx: http://cnedelcu.blogspot.fr/2013/09/nginx-error-413-request-entity-too-large.html

server {
    client_max_body_size 500M; # allows file uploads up to 500 megabytes
    [...]
}

Sorry for the noise.
