I don't say it's the solution for your problem, but I had also a problem with receiving mails from gmail. Gmail use always TLS, and couldn't find password for the server.key file. So the only thing I did: I removed the passphrase from the server.key file (openssl rsa -in www.key -out new.key) and everything was ok .. (new keyfile name needs to be the same as old keyfile name, so backup your old keyfile with another name)

is the problem can be solved if i disable tls connection from admin Console ???

[Sam159]

I disabled TLS Only

[Mido3mad]

we use multiserver Installation so i disable it in General Settings or on one server?

[Sam159]

I only use one server, so I disabled it on server settings, TLS authentication is then still available but other authentications too... IF you check TLS only, it only accept TLS authentications

Still have same problem :|

A log entry showing a server disconnecting immediately after they connect with no other error listed is not indicative of a problem at all. Most of the time this is a) someone scanning the network to see if there are mail servers around they can abuse, b) ISPs receiving email you sent that are checking to see if the MX for your domain actually works before accepting your mail, or c) your monitoring systems checking to make sure things are working (if you're running email for a business you should have monitoring of some sort).

Are you getting email from nobody at all? Or is email from some places working fine, and just from these specific places you're not getting any?

it was working perfectly this happened later and from some mail servers its delivered fast from the first connect
i get mails also from gmail now but with delay time can be 20 or 30 minutes with same connect and disconnect message repeated in each time gmail try to send it again till the connection established and send the message its wasn't happened before
