Thanks to you & Paul for your input. Despite sendmail being turned off in rc.conf (and never used in 5+ years), there was a sendmail process running. Simply killing the sendmail process rectified the problem. So it appears that sendmail was being used to send mail from SQMail, although Postfix was being used to send mail from SMTP clients and the command-line mail command. I'm not sure why this should be. Apologies for bringing this to the list, none of the research I had done led me to this conclusion and I appreciate the help.
