What's new in 184.108.40.206 since 220.127.116.11:
[-] Fixed an error of simulteneous access to the ACCOUNT.ATB file which could lead to write error to this file when multipile accounts with OAUTH were trying to simultaneously write to this file[+] A command-line option /SMTP_DELAY_AFTER_SEND:N to specify delay in milliseconds to wait after sending each message, before sending a new message. This delay may only be made if several messages are sent during a single SMTP connection. For example, for 2-second delay, specify /SMTP_DELAY_AFTER_SEND:2000. Minimum value is 1 and maximum is 60000. After sending a message, you will be able to see SMTP status "Delay N ms..." if this option is active.
