Hi,

There are so many things that could be going on here. I'm guessing that you're attempting to send e-mail from your own Linux box, using its own local MTA (Postfix, sendmail, etc), and that when you try to send e-mail to your GMail account you get these bounce messages.

Again this is a pure guess since you've not really given us much to go on here, but if (for example) your Linux box has a hostname of foo.company.com, and you're logged in or otherwise running as 'root' at the time, then mail you send from the command line or otherwise directly through your own MTA will go out as 'root@company.com'.

Now, GMail (and many other mail services besides) tend to do all kinds of checking on incoming e-mail to determine whether or not it's valid. One of these checks can be to determine if the apparent e-mail address the sender is sending as actually exists. Now, if your company doesn't have an e-mail address called 'root@company.com' it will fail this check, and GMail will bounce the mail.

Note that if this is what is happening then this is 100% correct and valid behaviour. You almost certainly don't want to be sending mail out from your workstation as 'root@company.com'. Instead, in whatever script or command or program you're sending your mail, you need to set a valid 'From:' address to use instead. That way, mail has a better chance of going out succesfully.

Also, if your company has an e-mail gateway for sending outbound mail from, configure your own local MTA (Sendmail, postfix, etc) to be a smart relay, instead passing all its own local mail to that relay. Or just directly send out to that corporate mail relay instead, rather than submitting e-mail locally. That would be best practice in general, if you have such a facility to make use of.

Hope this helps.

mlmmj-send(1)						      General Commands Manual						     mlmmj-send(1)

NAME

       mlmmj-send - send mail to a mailinglist or similar

SYNOPSIS

       mlmmj-send [-L /path/to/list | -l listctrl] -m /path/to/mail [-a] [-D] [-F] [-h] [-o] [-r] [-R] [-s] [-T] [-V]

       -a: Don't archive the mail

       -D: Don't delete the mail after it's sent

       -F: What to use as MAIL FROM:

       -h: This help

       -l: List control variable.

       -L: Full path to list directory

       -m: Full path to mail file

       -o: Address to omit from distribution (normal mail only)

       -r: Relayhost IP address (defaults to 127.0.0.1)

       -T: What to use as RCPT TO:

       -V: Print version

DESCRIPTION

       This binary is used to send all kinds of mail to mlmmj managed mailinglists, but can potentially be used standalone for sending mails.

       The only option that is not self explanatory is the -l list control option:

	      '1' means 'send a single mail'

	      This is used together with -F and -T to send one mail to one recipient.

	      '2' means 'mail to moderators'

	      Used for sending mails to the moderators of a list.

	      '3' means 'resend failed list mail'

	      '4' means 'send to file with recipients'

	      '5' means 'bounceprobe'

	      '6' means 'single listmail to single recipient'

BUGS

       This  manual page is very scarce documentation of the mlmmj-send binary. The reason for this is that it's really not supposed to be used by
       any human, but only supposed to be invoked from other mlmmj binaries. So in case more documentation is needed, please read the source.
