Hi,
We are using iRedmail-0.6.0 Based on CentOS 5.5 which for RoundCube Webmail. It is back end OpenLDAP.
From the last 15 days, there are no mails are delivering to gmail. But it is ok in yahoo and other mail.
When we send mail to gmail, it shows successfully sent to gmails. but no mail received in gmail.
And when we send mail from gmail to roundcube webmail, that mail is returning message to sender.
If you have any solution please inform me.
