Hello This is rather urgent: does anybody know how I can simply set the Reply-To: and the From: fields for mails "dynamically"? This is on a Linux machine and mail is sent using mailx's mail program. The MTA is sendmail (which I know little about). If there's anything as simple as setting an appropriate environment variable, that'd be just cool. The mail sending is done inside a (bourne) shell script. TIA Sven (please CC me)
