your squirrelmail may get hacked by old version bugs and or php bugs and using binary postfix sendmail for sending out therefor it does not use some postfix smtp auth mech for deliver out, you may never find some account in the webmail log and if you might find , it will not be any help also you stated before that you have no idea from smtp auth stop the server, check your whole setup inkl webmail , update all related software and linux distro, read postfix docs, perhaps hire somebody near your for help come back for questions then, after all done start the server again thank you for using postfix -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria
