<p>Hi,</p>
<p>this sound correct, here is my fstab entry:</p>
<p><i>XXX.XXX.XXX.XXX:/mail-storage /mnt/mail-storage nfs
defaults,timeo=30 0 0</i></p>
<p>Here are my options when doing "mount":</p>
<p><i>rw,relatime,vers=3,rsize=262144,wsize=262144,namlen=255,hard,proto=tcp,timeo=30,retrans=2,sec=sys,mountaddr=</i><i>XXX.XXX.XXX.XXX</i><i>,mountvers=3,mountport=50141,mountproto=udp,local_lock=none,addr=</i><i>XXX.XXX.XXX.XXX</i></p>
<p>How can I do further test?</p>
<p>Thanks in advance</p>

<pre class="moz-quote-pre" wrap="">problem still occurring, I just noticed that if I do an "ls -l /mnt/mail-storage/<user>/Maildir/cur/" from the Dovecot server I can unblock the mailbox of the user and Thunderbird can receives all the e-mails.
The problem occurs even with the gmail client on the smartphone.
I just tried many things but can't find a solution.
I just reinstalled a new server with mail storage not on NFS and the problem seems to be fixed, but this is not a solution valid for us as we would like to use NFS.
