UNIX for Dummies Questions & Answers

Dear all,

I've been working with AIX for, um, 15 years now and I have read all I can about the above, but I am stuck. Everything seems to point to using sendmail on the command line to embed a uuencoded attatchment will not work.

Using something like "(cat plain.txt;uuencode attach.file targ.type) | mail addr@server" works fine, but I need to use the features of sendmail that allow the sender's identity to be changed.

We currently use the latter function in a unix password reset script to e-mail the generated password to the user's MS Outlook account, but we hide the sender and replace it with the helpdesk so if they reply, the mail ends up in a sensible place as there is no route to direct mail back tot he unix host.

Is there anything in the mail command that would allow the function?

I am aware that this could be used for devious reasons, so if anyone would prefer to respond directly rather than posting, I would hope that could be arranged.


Thanks, in advance,
Robin

I don't know about AIX, but .on Solaris' "mailx" one can specify a '-r ReturnAddress' and have all replies to the original email go to the 'ReturnAddress' instead of what's been specified in the 'To:'.

This might also be a more generic way of dealing with it.

Code:

"(cat plain.txt;uuencode attach.file targ.type) | /usr/lib/sendmail -oi addr@server"

You can tack on whatever other sendmail options you want as well, like -f to specify the envelope return address etc.

HTH,

-c

p.s. not sure where the sendmail binary is in AIX, assuming /usr/lib as per solaris, but i just don't have an AIX machine available at this minute to double check!

Hi guys

I had some nice HINT

if you have problems recieving attachments, make an entry in the script to change the permisions for the uuencode file

chmod 666, works on Solaris 5.8
