Using -DEBUGX or -DX parameter to test SMTP or ESMTP server reveals step by step information exchange between SMTP server and Command line email software. Every byte of information is displayed as it is sent over the SMTP protocol, allowing user to precisely locate the problem or SMTP server incompatibilities as they happen.
When trying to debug or test SMTP server or just trying to find a cause for email not being correctly delivered to SMTP server, -DEBUGX parameter may come at hand by providing the most important information about communication session with SMTP server.
C:\>febootimail -SERVER smtp.server.com -FROM firstname.lastname@example.org -TO email@example.com -MSG debug SMTP or ESMTP server -DEBUGX
Note that due to -DEBUGX implementation that is intended to provide user with full information when testing SMTP server or trying to locate mail sending problems, it is rather advisory not to send messages with large attachments for testing purposes.
To store SMTP communication use redirection operator > and file name. It is recommended to use absolute path to easier locate SMTP communication debug file. If path is not specified, file is created in current folder. The location of default folder is automatically determined by the folder in which febootimail is executed.
C:\>febootimail -SERVER smtp.server.com -FROM firstname.lastname@example.org -TO email@example.com -TEXT Log SMTP server information to text file -DEBUGX > C:\email-debug.txt
