 no SMART_HOST I recently migrated from Fedora to CentOs and forgot to configure SMART_HOST in sendmail.mc. I discovered this after my ISP cut off my internet access because they say I was sending spam. Would the lack of a SMART_HOST make ordinary mail look like spam to an ISP? How come outgoing e-mail worked at all?  |

Are you sure they said you were sending spam? If so, ask them for a copy of the spam so you can investigate. Most likely, what they were really complaining about was that you were running a mail server and you weren't supposed to be. Outgoing e-mail worked because you delivered it, which you're not supposed to do unless you're running a mail server. DS |

I finally got around to reading mail to root and I now see what happened: the outgoing mail was mostly rejected by the destination sites and returned, no doubt with a nasty complaint to the ISP. Mea culpa. Bob T. |

Many ISPs automatically flag inbound mail arriving directly from dynamic IP addresses as spam. > How come outgoing e-mail worked at all? Your ISP doesn't block outbound port 25 from dynamic IP addresses. -- John (john@os2.dhs.org) ** Posted from http://www.teranews.com ** |
