PORTABILITY

POSIX.2. x/OPEN Portability Guide 4.0. UNIX System V.

UNIX System V has a compatible mailx utility while Berkeley systems have a similar utility

known as Mail.

The –d, –F, –r, and –U options, the Copy, echo, followup, Followup, Save, Unread, and

version commands, and the

allnet

conv

onehop

replyall

sendmail

, and

sendwait

variables are extensions to the POSIX standard.

MPE/iX NOTES

Since the current MPE/iX implementation of mailx does not support the native MPE mailer,

you cannot use it to send mail to other systems. On MPE/iX, it uses the tsmail delivery

agent.

Also,since an MPE/iX child process cannot survive the death of its parent, you should always

use mailx with the variable

sendwait

turned on. By default, this variable is turned off; how-

ever, the default system conﬁguration ﬁle for mailx (/etc/mailx.rc) contains a line that

turns it on.

For more information on how the current

MPE/iX implementation may affect the operation of

this utility, see Appendix A, MPE/iX Implementation Considerations.
