I have my Nethserver setup using the getmail multidrop method, and in the most part it all seems to function OK, both sending and receiving emails.
However, it has been brought to my attention, that some users have received messages and the attachments are missing.
It is not a specific user, nor do I think its a specific attachment.
Most users receive a variety of attachments OK throughout the day.
On inspecting the issue, I can see the mail has an attachment on the webserver where the mail is delivered.
I can then see getmail in my logs retrieving the mail, which is pretty much the filesize as the master email on the webserver.
I then see the local delivery to its recipients, with a much lower bytesize, hence no attachment.
Now, whether coincidence or not, those messages received seem to be delivered locally in plain text format.
Note the getmail size (81289 bytes) , and internal mail delivery, size=9677

I have turned off any mail filtering, spam checking, virus checking, but still cant seem to cure it.
Any help would be appreciated.
