[imp] Random attachment problems

[Michael M Slusarz]

Quoting Babita <brana at ualberta.ca>:

> Horde: 3.1.4
> Imp: H3 (4.1.4)
> PHP Version: 4.4.1
> OpenBSD 4.1
>
> Hello.
>
> We're seeing two major problems on our system related to attachments and
> we're having a difficult time isolating the cause.
>
> 1. uploading certain file types (eg .java and .vms) causes the composition
> screen to go blank.
>
> .vms fails on all browsers except IE 7.0
> .java fails on Safari 2.0.4 but succeeds on Firefox 1.5 (on machine A)
> .java fails on Firefox but succeeds on IE (on machine B)
>
> 2. sometimes the file does not attach despite the "successfully attached"
> message confirmation (ie, the file does not show up in the recipient's
> email).
>
> .jpeg has inconsistent results on both Safari and Firefox
> .jpg and .gif are successfully received every time
>
> These files are no more than 1.5MB in size and do not exceed any upload
> limits. All front end machines have a common NFS mounted upload directory.
> We recently upgraded from Horde 3.1.2 and Imp 4.1.2, applying patches
> incrementally to get to the latest stable release. None of these problems
> existed on the old system.
>
> Any help is appreciated.

I'd start by disabling MIME magic code and see if that helps.
