Hi,

In Slackware9.1 my user name is peter and my e-mail address is heisspf@isp.net

Apparently mail I send arrives From: peter@isp.net. Therefore, when the
recipient makes a "reply" the mail bounces since naturally peter@isp.net is
not found.

My mail program is exmh.

Can that be corrected w/o changing my user name?

Thanks & regards
