If you have a custom domain, you can add arbitrary email addresses in your domain. An email address may forward to any other email address on the Internet. To simply cause an email address to forward to your mail account, specify your username as the destination.

Thus the classic Linux environment tries to provide useful command-line tools including programs for reading Usenet news and electronic mail. It's expected that as a user in this environment you don't mind reading online manuals now and then (with the “man” command), and you write, or would some day like to write, shell scripts or procmail recipes… text/html 2009-09-26T15:10:48-08:00 http://info.rahul.net/classic:classic_linux_dot_files?rev=1254003048 A so-called “dot file” is an initialization file whose name usually begins with a dot.

He can then supply such email addresses to others. For example, he could tell his school to use the address joeuser-school@rahul.net when sending him email.

At the shell prompt on any Classic Linux machine, type scan.logs -h for help. If you think somebody sent you mail but you did not receive it, scan.logs can be used to find out if it arrived on our servers and was rejected for some reason.

You don't want to completely switch off SMTP filtering, but you still want to receive mail from that sender. Although our SMTP filtering does not allow a specific sender to be white-listed, you can take advantage of our Email Hyphenated Suffixes feature.
