I'm puzzled by MASQUERADE_AS and MASQUERADE_DOMAIN in sendmail.mc . I'm using KMail (under Fedora-12) on my laptop to send and receive email. I send my email through my ISP, as defined by define(`SMART_HOST', `smtp.eircom.net')dnl in /etc/sendmail.mc on the laptop. I collect my email on my desktop from my ISP and other sources, by running fetchmail as cron.d jobs. I run dovecot IMAP on the desktop, and read the email on my laptop as IMAP. Should I set MASQUERADE_AS and/or MASQUERADE_DOMAIN on laptop and/or desktop? Currently I have them both set on both machines to my ISP, MASQUERADE_AS(`eircom.net')dnl MASQUERADE_DOMAIN(eircom.net)dnl but I'm not sure if this is necessary, or wise. Any enlightenment gratefully received. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
