I''ve had to send this from a browser as I can send e-mails via Evolution. mira.net were bought out by pacific.net.au some years ago, but I still keep using the mira domain name. I can receive e-mails O.K. but some replies or new e-mails are sent and received by the recipients, whilst others are blocked. I''ve read documentation until my eyes have turned rectangular. All I want to do is send e-mail!! Thanks for any help. Debian 2.6.22-3-686 lenny/sid on Toshiba A200 laptop. Evolution 2.12.3. Exim4 version 4.68. Below is a snippet from mainlog from today when I tried to send a message to a yahoo account and a test message to yourselves. 2008-04-03 20:35:31 1JhYxv-0002Tu-TO <=3D robstone at mira.net U=3Drob P=3Dlocal S=3D477 id=3D1207265721.8719.0.camel at roblaptop 2008-04-03 20:35:35 1JhYxv-0002Tu-TO ** help66less at yahoo.com.au R=3Dsmarthost T=3Dremote_smtp_smarthost: SMTP error from remote mail server after RCPT TO:<help66less at yahoo.com.au>: host mail-pacific.pacific.net.au [61.8.0.22]: 554 5.7.1 <help66less at yahoo.com.au>: Recipient address rejected: Access denied 2008-04-03 20:35:35 1JhYxz-0002U3-Ok <=3D <> R=3D1JhYxv-0002Tu-TO U=3DDebian-exim P=3Dlocal S=3D1465 2008-04-03 20:35:35 1JhYxv-0002Tu-TO Completed 2008-04-03 20:35:37 1JhYxz-0002U3-Ok ** robstone at mira.net R=3Dsmarthost T=3Dremote_smtp_smarthost: SMTP error from remote mail server after RCPT TO:<robstone at mira.net>: host mail-pacific.pacific.net.au [61.8.0.22]: 554 5.7.1 <robstone at mira.net>: Recipient address rejected: Access denied 2008-04-03 20:35:37 1JhYxz-0002U3-Ok Frozen (delivery error message) 2008-04-03 20:36:30 1JhYys-0002UY-CV <=3D robstone at mira.net U=3Drob P=3Dlocal S=3D534 id=3D1207265790.8719.2.camel at roblaptop 2008-04-03 20:36:33 1JhYys-0002UY-CV ** pkg-exim4-users at lists.alioth.debian.org R=3Dsmarthost T=3Dremote_smtp_smarthost: SMTP error from remote mail server after RCPT TO:<pkg-exim4-users at lists.alioth.debian.org>: host mail-pacific.pacific.net.au [61.8.0.22]: 554 5.7.1 <pkg-exim4-users at lists.alioth.debian.org>: Recipient address rejected: Access denied 2008-04-03 20:36:33 1JhYyv-0002Ud-2V <=3D <> R=3D1JhYys-0002UY-CV U=3DDebian-exim P=3Dlocal S=3D1586 2008-04-03 20:36:33 1JhYys-0002UY-CV Completed 2008-04-03 20:36:35 1JhYyv-0002Ud-2V ** robstone at mira.net R=3Dsmarthost T=3Dremote_smtp_smarthost: SMTP error from remote mail server after RCPT TO:<robstone at mira.net>: host mail-pacific.pacific.net.au [61.8.0.22]: 554 5.7.1 <robstone at mira.net>: Recipient address rejected: Access denied
