Sophia, Sorry, I'm not familiar with SUSE, and I don't know if that distro offers a better way to do what you want. Using an opensource sendmail I think there's not a "quick" way to cover your needs. Sendmail can be configured to meet your requirements but this topic can't be covered in few lines. A little hint: the "check_compat" ruleset could be the right place to check if the sender can use the recipient; I think you'll need also to customize the "check_mail" ruleset to ensure that "sender" corresponds to the "user" and that the "user" is authenticated; just to be paranoid: sendmail must be compiled with STARTTLS feature (user/password will be SSL protected)... The ouput of the command sendmail -d0.4 -bv root will tell you what features sendmail was compiled with; if you need more features, you must unpack the source tarball, define them in the <source tree of sendmail>/devtools/Site/site.config.m4 and recompile/reinstall sendmail; beware: unless you install your sendmail in a different place, the next rpm install/upgrade will substitute your binaries with the standard ones. In the sendmail source tree there are two useful README: one in devtools subdir which explains how to recompile sendmail; and one in the cf subdir, and this explains how to build an .mc file (the guide to build the .cf one). A third useful file is the op.ps located in the doc/op subdir. (redhat sendmail-doc rpm contains all three docs).
But if you want to tame sendmail you _must_ buy and read the Sendmail bat book, 3rd edition.
Best regards G
