(Not to be confused with “FTPS”, which is the FTP protocol over SSL/TLS.) Most people familiar with FTP know about transfer modes: binary and ASCII. A file […]
Question: With the SMTPQ service, do you have some guidelines on the best practice settings for the number of threads required for sending different quantities of email?
