<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">I am using OpenSuSE 12.3, KDE 4.10.5.</p>

<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Back in the day I used spam filtering but with the introduction of Kmail2 I discovered that one IMAP email hosted on an Exchange server would keep downloading the same email over and over when filtering was active on that or all accounts.</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; "> </p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">I have since discovered that by turning off spam filtering for that IMAP account the situation resolves itself and I only receive one copy of any given email.</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; "> </p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">I have reported this as a bug in the past that is reported as being a duplicate of one of many other bugs. Sorry I am not technical enough to sort those out. However for what it’s worth selectively turning off filtering to offending accounts cured this problem for me.</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; "> </p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">I wonder if the same issue is not causing other filtering issues for others. Try turning spam filtering off for offending accounts to see if that resolves problems.</p></body></html>
