Dear J�rgen, I downloaded the latest CVS last night, and tried archiving some emails into ARCHIV. While many of the emails had attachments, there were no large attachments. The received folder had 395 emails, and size 5.8MB.
Method 1. Using the folder controller. Here I simply copied received from $user/Mail to $user/Mail/ARCHIV. Depending which time I did this, the archived version had 135, 102 or 395. emails in $user/Mail/ARCHIV/received (file size 3.9MB). It seems unrepeatable in exactly how many emails are in the archived folder. The folder is gzipped, but if one renamed it received.gz, then try and gzip -d it, one gets "invalid compressed data-format violated". This was done repeatedly on the same folder, brought out of the back-up every time. I closed down xcmail. It would not restart. The only way to restart was delete all files, and copy from my back-up of the Mail directory. Clearly something was set in this directory which prevented xcmail starting - it was not a setting in $home/.XCmail directory. Method 2. This was to highlight a number of emails in the received folder, and then Move them to an existing received.gz file. In small numbers, e.g. 15, this seemed reliable. To do a lot, e.g. 50 or 100, then it would appear to start loosing emails. But again, not predictably. After each 15, I would check that they all had been moved correctly. It is a very slow way of backing up! Maybe the problems are due to any particular attachment in some emails - whether it be html, which is the most likely attachment in this folder, or something else. I have all the folders etc archived up, so can run any particular test on it. Regards, David Pilgram.
