When we loaded the XML file in the SwithMail GUI and tested it, it sent successfully. If we reduce the attachment size to 9Mb, the mail completes successfully from batch file and GUI. Does SwithMail have any kind of problem with large attachments?

This is probably a limitation on either your SMTP server being used, or on the recipients side for message size limits. Author Posts You must be logged in to reply to this topic.
