Emails with .exe attachments being silently deleted

[stilbury]

I have had several clients complain that emails with executable attachments are dissapering, I traced this to the exim filter at /etc/antivirus.exim, and with the help of this wise advise of this forum (using the search) found out how to edit it (PICO).
My question is many of these attachments I want to remain blocked and the sender recieve notifiction of the failure, which they currently do not (and never have).
is there a -verbose setting or something i should enable ?

Thanks in advance

Wish it was easier to change the list of extensions, becasue as a programmer I'm always sending .exe's and .reg's out and I only just found out they where being wiped... crappy setting!

Could you not rename the file extension to something obscure like .kjl or .tou etc. thats not on the filtered list, then tell the recipient to rename them back to the original .exe or what ever. You could also wrap them up in a .zip or a .rar compressed file for sending.

I just looked at the antivirus.exim file and I would be loath to change anything in there.

Here is the current list of filtered extensions ad[ep], ba[st], chm, cmd, com, cpl, crt, eml, exe, hlp, hta, in[fs], isp, jse?, lnk, md[be], ms[cipt], pcd, pif, reg, scr, sct, shs, url, vb[se], ws[fhc]

You could, but half the people I deal with don't follow instructions anyway, meaning that I get the file don;t wokr, or worst still they copy the renamed exe (I'm a programmer) then run the original (as they didn;t rename) and I'm told that the issue still happens!

Just deleteing sent emails because they don't meet someone elses specs is a poor show. At least give us an exim options for files to filter.

I notice in WHM Feature Manager/Edit a Feature List/default Edit/Email Filtering Manager can be unchecked to diasble the filtering.

You could create a new feature list and give it a name and edit your packages to give users this unfiltered feature list in their packages. This may have been cPanels answer to this issue, who knows.

Yours is a crappy practice. Adapt! You might get some sympathy for exe's. But reg files? Come on!

Even if you allow the mail through your cPanel server (my preference), there is still a chance that it will never reach its recipient based upon client side filtering. Allowing those types of file attachments is dangerous. If a user cannot figure out how to rename a download or unzip a file, I certainly would not want them to be open to any all types of exe and reg traffic.
