that the SMTP greeting failed Article Number: 400 | Last Updated: Wed, Aug 17, 2011 11:38 AM Summary Users report that some messages are returned with the explanation that the SMTP greeting failed because no valid DNS name or pointer record was identified. Details When a message is sent through SMTP, the client and server are expected to identify each other. This identification http://kb.kerio.com/product/kerio-connect/server-configuration/managing-logs-in-kerio-connect-1126.html is part of the SMTP greeting. The following example is a simplified version of a mail server (mail.sender.com) successfully transmitting a message to [email protected]: mail.sender.com connects to mail.recipient.com mail.recipient.com accepts the connection and identifies itself "Hello, I'm mail.recipient.com". mail.sender.com identifies itself "Hello, I'm mail.sender.com". mail.recipient.com acknowledges mail.sender.com http://kb.kerio.com/product/kerio-connect/troubleshooting/general-errors/cannot-send-to-some-mail-servers-with-the-explanation-that-the-smtp-greeting-failed-400.html and says, "OK, give me your message". In the above example, mail.recipient.com has allowed mail.sender.com to transmit the message. In order to prevent spam, some mail servers will validate the name provided by the connecting mail server before allowing the message to be transmitted. The following example is similar to above, however mail.sender.com will provide a false name, and therefore mail.recipient.com will refuse to accept the message. mail.sender.com connects to mail.recipient.com mail.recipient.com accepts the connection and identifies itself "Hello, I'm mail.recipient.com". mail.sender.com identifies itself "Hello, I'm mail.anothersender.com". mail.recipient.com determines that mail.anothersender.com is someone else, or does not exist and says, "You are not who you say you are, Goodbye". mail.sender.com will then return the email to the original sender address, quoting the reason why it could not deliver the message. For example: I'm sorry but I could not del

using Outlook PST files, they will sooner or later reach the maximum file size possible and their mail will break (actually, with Outlook it will usually break before that). Sometimes you http://aplawrence.com/Kerio/fixing-large-mailboxes.html can fix it with SCANPST.EXE, sometimes you can't. If you are using Imap or https://en.wikipedia.org/wiki/Kerio_Connect Kerio Outlook connector, you won't see quite the same problem. Kerio stores mail messages individually on the server, so you are never in danger of reaching file size limits - well, technically you still could because the directory itself could grow too large, but that would take an unimaginable number of messages.Even so, having a lot of messages kerio control is a problem. It slows things down: if you have 40,000 messages in your INBOX, think about what happens at the system level when a new message arrives. That directory with 40K items already in it has to be scanned to find a free spot to stick the new entry. It takes time to scan a big directory; if you have dozens of users all with giant INBOX files, the arrival of kerio control log new email can really slow the system down. That's just the OS: Kerio itself maintains indexes of the messages, and every new message requires adding to that ever growing index. Note that there's nothing wrong with having large mail folders. It's having large mail folders that need to be accessed frequently (INBOX, Junk Mail, Deleted Items) that is the problem.So what's the solution? Well, you could just drag and drop a bunch of messages into a new folder, and if you had been doing that regularly before you got up to tens of thousands of messages, that's fine. But once you get a very large directory, it stays large even when it becomes mostly empty - it still takes extra time to scan through it. So what to do? With Kerio, the solution is pretty simple. Stop the mailserver. That's usually done with the Kerio Engine Monitor, though on Linux you can do it with "/etc/init.d/keriomailserver stop". Now rename the oversized directories for each user to something else. You might rename their INBOX as "Inbox201412", for example. Do the same for large Deleted Items and Junk mail folders. Restart the server; new mail will cause Kerio to automatically create any folders it needs (INBOX, etc.), but they will now be small and quickly sca
