<div>I don't see how using delayed expunge would really be consider abuse, the documentation makes mention of its use for this very reason.<br></div>

<div style="font-family:Arial;">You will hit performance issues. All expunged messages need to be scanned over at every select and refresh.</div>

<div style="font-family:Arial;">If you are replicating to a system that's backing up, then you need delayed delete to ensure everything gets replicated.<br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;">The backup system that's in development uses the sync protocol to feed the data from Cyrus into the backups.</div>
<div style="font-family:Arial;"><br></div>
<blockquote type="cite"><div><div>We use rsync to make a duplicate of the email spool to a file server at regular intervals, which eventually makes its way to tape. Although we don't have regulatory requirements I've had to do a few recoveries and have done so without problem. <br></div>
<div><br></div>
<div>in our case we have cyr_expire set to 3 days (I believe the default config), which provides more than enough time to in case a backup fails for some reason or another.<br></div>

<div style="font-family:Arial;"> <a href="http://www.mailpiler.org">http://www.mailpiler.org</a> (Fully Free Software)<br></div>
<div style="font-family:Arial;"> <a href="https://www.mailarchiva.com">https://www.mailarchiva.com</a> (the old version is opensource but the<br></div>
<div style="font-family:Arial;"> latest is closed)<br></div>

</blockquote><blockquote type="cite"><div><div><div style="font-family:Arial;">The specific software will be much better for searching the archive.<br></div>
<div style="font-family:Arial;"> Finding something in the delayed_expunge folders after many years of<br></div>
<div style="font-family:Arial;"> archive will absolutely be a nightmare!<br></div>
