Hi Folks,

I am running qmailtoaster on COS6 32 bit.

Send and receive error message coming frequently and inbox emails are not downloading in outlook 2016 of office 365 email client.

But if i restart the dovecot service then start downloading the emails in inbox then send and receive error message gone.

Outlook 2010 doesn't have the same issue.

Is this server issue? or email client version issues? or if i need to use standalone outlook product instead office 365?

I do the dovecot service restart every one hour for this issue .

if possible to do the cron job for dovecot service restart for every one hour daily or any other solution there.

Kindly Any one help me.
