Hi, I recently upgraded my backup mailserver to FC2 and now when using the etrn.pl script from my primary mailserver, I get the following error from it: # /usr/local/bin/etrn.pl backup-mx.domain.com domain.com ETRN not supported On the backup-mx.domain.com machine the following is output in the /var/log/maillog: Aug 15 12:28:47 primary-mx sendmail[515]: i7F2SkMq000515: primary-mx.domain.com [xxx.xxx.xxx.xxx] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA The etrn.pl script is the one used for: sendmail-8.12.10-1.1.1 Any ideas where I should start looking at this problem?
