--- Quote ---Some file types are blocked
As a security measure to prevent potential viruses, Gmail doesn't allow you to send or receive executable files (such as files ending in .exe) that could contain damaging executable code.

Gmail won't accept these types of files even if they are sent in a zipped (.zip, .tar, .tgz, .taz, .z, .gz) format. If this type of message is sent to your Gmail address, it is bounced back to the sender automatically.

You can send and receive messages up to 20 megabytes (MB) total (including attachments). Any message that exceeds this limit will not be delivered to your inbox and will be returned to the sender.

I got the bounce back.  6.91MB inside a tar.gz  :( 

I'll email with other arrangements.

I didn't know that gmail looks inside tarred and zipped attachments.  But executable files normally don't cause a problem that I have seen.  Perhaps it also looks for file extension like .bin in addition to .exe.

softwaregurl:
It might have been a combination of the file name looking like a tar ball and the complexity.  Two files with tar headers inside the big one.   I was reading where clamav can reject too complex of an archive as a DOS attack.  Or failed a hierarchical scan or complex enough looking that it was scanned more then normal (or the scanner was bored : :P.

tobiaus:
i would have tried zip.tce just because i'm used to zip files offering fewer problems for uploading and downloading (sometimes) and you can zip a tar.gz. in theory it should make no difference to the scanner, in practice it may help.

other than that, wikipedia lists free file hosts for files of that size. just upload and copy the url here. no account setup needed, although they may not be private.

Jason W:
I wonder if making  an iso file system using mksiofs or a cramfs image would pass the scanner as it is looking inside tarred archives but perhaps not iso images or cramfs images.  When I get this extension I will try that sort of thing out abnd mail it to myself and see if it makes it through.  There has to be a format that gmail does not peek into.
