EMAILX Troubleshooting
Resources available to you for troubleshooting EMAILX problems include the log file, the SMTP response codes, and the A-Shell forum. See below for details.
Log file
The first go-to troubleshooting tool is the log file. Before spending much time on anything else, we highly recommend editing your CFG file to add LOGFILE and LOGLVL entries and then examining the log after the failure. Here's an example for a GMAIL session with LOGLVL=4 ...

Each line starts with a timestamp showing the date, time, program-user-job#, then either ">" for outgoing commands or "<" for incoming responses, followed by the command or response text, or a description thereof. Lines with no directory indicator are just reporting internal status (like the socket # on the second line), or are reporting a breakdown in the protocol (such as a timeout). Lines with no timestamp are generally continuations of a multi-line response. Most SMTP responses start with a three-digit numeric code indicating the status (as part of the SMTP protocol - see the table below), and are followed by some non-standard explanatory text. Some messages may contain the word "Status" followed by a number, often negative, indicating a local library error code, as in the following examples...
> Checking for data... [Status=-10057 (A request to send or receive data was disallowed because ...)]
> Opening socket mail.optonline.net (port 25) Flags=1... [Status=-10060 (A connection attempt failed because ...)]
*** (Status -10049) ***
Usually the error code is followed by a description, but if not, you can usually look them up on the Internet. In the case of Windows, search the Internet for "Windows System Errors"; for Linux, try "Linux errno values".
