<BR><FONT SIZE=2>> Hi,</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> Be aware that also your .subscriptions file and .customflags </FONT>
<BR><FONT SIZE=2>> are not nfs safe (yet) in dovecot-0.99.10.</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> I know Timo is working on that though :)</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> Kind regards,</FONT>

<BR><FONT SIZE=2>> Ps: I have a "crude" patch to make .subscriptions and </FONT>
<BR><FONT SIZE=2>> .customflags nfs aware (I can not guarentee it is nfs safe ;-).</FONT>
<BR><FONT SIZE=2>> My own setup runs on nfs with the indexes in memory.</FONT>
