Oops, I changed doc but forgot to commit, will commit later (out of office now).

The changes are:

- don't block "zip"
- don't block "wmf"

Now it seems to work correctly. Thank you.

Can you tell me what has changed in the amavisd.conf for this fix? As far as I can see there is no difference in what is on the upgrade tutorial page compared to what I had previously. I have refreshed my browser page.

Me too, I would like to know what is changed in update tutorial, but can't find a difference.

Thanks for the feedback and help. Repacked iRedMail-0.9.6 with this fix, also updated upgrade tutorial.

There isn't a .wmf attachment. There is only an .xlsx file attached. As this is a test email, I know what is in it.
This new feature I will be keeping off our production server until I can explore further.

A "Strict open xml-document (xlsx)" is a zip archiv which could contain a windows meta file picture.
But in my case an excel file example.xlsx with a wmf-picture isn't banned whereas the same file renamed to example.wmf is banned.

A .xlsx file is virtually a zip archive containing a number of files so maybe the .xlsx zip archive contains a .wmf file inside?

Thanks for the reply ThASattler. Here is the postmaster message:

The reason of banning this mail is there is an attached file with file extension .wmf.
You can remove 'wmf|' in section of  '# Dangerous file name extensions' in Amavisd config file.

Hi dsp3,

you should enable administrator notifying about banned mails

change in /etc/amavis/conf.d/50-user:

$banned_admin = undef;,

to

$banned_admin = "root\@$mydomain";,

and then post the mail to postmaster in the forum.

I suppose the reason is:
   

 [qr'T=x-(msdownload|msdos-program|msmetafile|wmf)(,|\t)'xmi => 'DISCARD'],

to

[b]$banned_admin = "root\@$mydomain";,[/b]

then postmaster gets an email and you can post the head of the mail in the forum.

I suppose the reason is [edit] (this was not right):
   

 [qr'T=x-(msdownload|msdos-program|msmetafile|wmf)(,|\t)'xmi => 'DISCARD'],

I have, but it still doesn't work:

Feb  3 12:38:04 mail amavis[18960]: (18960-01) Blocked BANNED (.dat,image1.wmf) {NoBounceInternal},

This is when sending .xlsx file created in Libreoffice

Did you restart amavis after making the change?

Yes
