Hello list,
I have a client who is trying to send email using his blackberry to addresses on the qmailtoaster and is getting the following 'chkuser' rejection: << -----Original Message----- From: "Mail Delivery System" <mailer-dae...@smtp12.bis.na.blackberry.com> Date: 05 Nov 2009 22:12:10 To: <SRS0=/y9rsq=gz=domainone.com=johnqpup...@srs.bis.na.blackberry.com> Subject: Delivery Status Notification (Failure) The following message to <janeqpub...@domainone.com <mailto:janeqpub...@acemt.com> > was undeliverable. The reason for the problem: 5.1.0 - Unknown address error 571-'sorry, sender address has invalid format (#5.7.1 - chkuser)' >> Is the following the solution: http://wiki.qmailtoaster.com/index.php/Chkuser_Settings And, how would a person accomplish this, by editing one of the 'c' files? I find it interesting that this doesn't always happen when a client sends from a blackberry. Thank you! Eric
