    Surely will NOT be sent as
    ?! Else that would open the spam-door WIDE?!

    I'll goog: gmail+%22multiple+aliases%22
    I've heard so, but at this rate I'd be dead before I opened THAT door.

    That will be great if it's possible.
    Gmail KNOWS me from my login and the first/easiest
    way to stop spam-Tx is to prevent a false "From:" field.

    Why did they introduce the extra hurdle of TxAuthenication
    and leave false "From:" fields open?

    I've got a 'hand crafted' pop & smtp facility, so that I can
    edit any thing down-to-the-last-bit.
    In fact, it's default mode, is that I must manually enter
    all fields, including "From:". Obviously I often make errors.
    BTW ISP2 also had a default M$ web-based mail and I was
    very happy with my modified ETHOberon set up for that:
    1 clik each for: DirOfPop, FetchSelectedOne, SendMarkedFrame.
    But ISP2 has been OOO for months.

    Investing the effort to pop gMail & smtp gMail will be justified
    if it ALSO solves the currently described problem.

    I'll seek my previous notes, to telnet/probe gmail.


    PS. ETHOberon allows easy pating between multiple apps
    viewable on the same screen. So here's some pop-headers.
    Do they show the <jump path> of the mailS?

    OK, I'm collecting info on 'sendmail+"smart host"', but even this
    best one is deficient: ---------------------
    ==> The SMART_HOST macro allows you to specify the host that should
    relay all outgoing mail that you are unable to deliver directly, and
    the mail transport protocol to use to talk to it.

    =\ Open your configuration file:# vi /etc/mail/sendmail.mcAppend or
    modify macro that read as follows
    :define(`SMART_HOST',`smtp.net4india.com')Replace smtp.net4india.com
    with your actual smtp server address. If line contains word, dnl
    remove the dnl word. Regenerate a new sendmail.cf config file with
    m4 command:# m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cfRestart
    sendmail service:# /etc/init.d/sendmail restart

    ==?==> WHAT is "your actual smtp server address" ??
    -> pgrep sendmail == na.
    ---------------- end of extract ----------------------
    By "your actual smtp server address"
    he must mean the ID of the sendmail-server-on-your-PC?

    Because your-PC will be sending to the remote <[email protected]>?
    So where do I find that?

    You'll need to use openssl s_client rather than nc/telnet, because
    gmail only accepts authenticated email via SMTP/SSL or possibly SMTP/TLS
    (I forget).

    Before investigating 'SMTP/SSL or possibly SMTP/TLS'
    I must confirm that mutt can send/reply without falsefying the

    I meant WITH a falsefied sender.
    So that I can let gmail pretend I'm the original ISP1-sender.

    I think you've misread my comment as its opposite. In the UK it is *not*
    normal to block outgoing SMTP traffic.

    Picking up on your reference to the proposed record keeping, I'm curious
    to know by what criteria an organisation would be judged in order for
    it to be determined whether it was permitted to run its own direct
    SMTP server. But I suspect we ought to take this sideline to its own
