  • Need help with SMART_HOST

    From Lew Pitcher@21:1/5 to All on Mon Sep 1 18:12:51 2025
    For the last 25 years, I've run sendmail, relaying my email through
    my ISP using the SMART_HOST sendmail.mc option.

    Over the weekend, my ISP introduced changes to their smtp service to
    require a login with password. Consequently, all my outbound mail now
    rejects with a
    451 4.3.5 <recipient email address>: Recipient address rejected: Server configuration problem

    Does anyone have any advice as to how I can configure sendmail 8.15 to
    send an appropriate userid (my ISP email address) and password?

    Any help or advice would be greatly appreciated

    Thanks, Marco

    That looks like it will work for me. I'll give it a try.

    This (and a couple of other changes that this lead to) fixed my problem.

    Thanks again for the assistance.
