I've been using a combination of Fetchmail and Sendmail to send and receive email with no problems every since I first started using Linux. Today, however, something weird happened that has never happened to me before. Sendmail suddenly started rejecting all incoming email with no explanation. It started saying that the domain does not resolve. For example: Jun 15 17:23:15 homerun sendmail[1373]: g5FMNFS01373: from=<speakup-admin at braille.uwo.ca>, size=3406, class=0, nrcpts=0, proto=ESMTP, daemon=MTA, relay=myrow at localhost [127.0.0.1] Jun 15 17:23:16 homerun sendmail[1374]: g5FMNGS01374: ruleset=check_mail, arg1=<speakup-admin at braille.uwo.ca>, relay=myrow at localhost [127.0.0.1], reject=451 4.1.8 Domain of sender address speakup-admin at braille.uwo.ca does not resolve It may have caused Fetchmail to delete some messages, but not all of them. Anybody know what could have caused this? I don't remember changing anything. For now, I have Pine using my ISP's Imap server and SMTP server directly, but this is slow over a dial up which is why I have always used Fetchmail and Sendmail. Any suggestions welcome.
