Error "<#5.5.2 smtp;554 5.5.2 Invalid data in message> #SMTP#" when you send attachment in your mail

Some users were receiving error <#5.5.2 smtp;554 5.5.2 Invalid data in message> #SMTP# when they sent message with attachment. The problem is when attached document name is longer than 50 characters. Some Firewalls have header size restriction and that limit blocks this messages to be sent. To correct this, change header limit on affected Firewall or shorten the name of the document you are sending (which is probably not good permanent solution).******
Update #1: Default header size limit in Exchange 2007 is 64K.Update #2: It might be the SMTP version problem. Mail is rejected with CONTENT-DISPOSITION error (overly long message header field for CONTENT-DISPOSITION) but not for all SMTP servers (same mail sent through different SMTP servers). If you send mail with attachment that has name longer than 50 characters from Exchange 2007 directly through DNS you may encounter this error, but if you send same mail from Exchange 2007 through smart host (other than Exchange) mail is d…

You change Receive connector port by opening the connector properties in Exchange Management Console --> Hub Transport --> RECEIVECONNECTORNAME --> Properties --> Network --> Local IP Addresses (Edit Receive Connector Binding)
Just to clarify what "Local IP Addresses" and "Remote Servers" are (from Exchange 2007 help), because I find it little bit confusing: Use these local IP Addresses to receive mail Use this list to specify the IP addresses and port numbers on which this Receive connector listens for incoming mail. Receive mail from remote servers which have these IP addresses Use this list to specify the remote IP address range fr…

Restore Time Machine backup from Synology

If you find yourself in a situation where you need to restore your Mac from a Synology NAS, you will find out pretty soon after you enter the recovery mode, that backup disk is not visible in recovery window. Steps need to be executed in order Recovery process to find NAS.

Best practise is to name Time Machine shared folder on Synology without spaces. Second, if you are using a password with spaces, which I strongly suggest from security point of view, always put it between ' ' example: 'This is my password'.

Enter the OS X recovery mode by holding Command +R (when Mac restarts and display is grey)When window with options is presented, select Utilities from the bar and select TerminalIn Terminal use following commands:Cd /Volumesls /laCreate a folder to mount Synology to by typing mkdir synologyNow mount your NAS by entering following commandmount -t afp afp://admin:password@10.10.10.11/TimeMachine synology Where admin is your username with administrative rights, passwo…
