System mail (Fedora 20)

[Robert Moskowitz]

I am joining this thread, as I tripped up on this once I got my old cron 
jobs transfered over to this install.  I have the following|

$ crontab -l
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=me

# For details see man 4 crontabs

# Example of job definition:
# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR 
sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  *  command to be executed
1 3 * * * rsync -tvz ftp.rfc-editor.org::rfcs/*.txt /home/common/ietf/rfcs
1 4 * * * rsync -tvz rsync.tools.ietf.org::tools.id/*.txt 
/home/common/ietf/drafts

Gets all the rfs and IDs  :)  And that is EVERY Internet Draft!

But that MAILTO= line is what causes the problem:

Dec 30 03:26:11 lx120e.htt-consult.com anacron[17136]: Job `cron.daily' 
terminated (mailing output)
Dec 30 03:26:11 lx120e.htt-consult.com anacron[17136]: Can't find 
sendmail at /usr/sbin/sendmail, not mailing output

Some cron config file is set to use sendmail for the MAILTO= option.

Lars has pointed out that logwatch config is coded to use sendmail.

We have a problem, Huston.

Frank seems to be pointing to a way to have mailx handle local 
deliveries, but just pointing me to AIX documentation on .mailrc does 
not do it for me.  I need a more complete set of instructions:

A howto setup mailx to handle ALL local mail delivery (for system and 
users).

If I need an MTA, can I just install postfix and all configs that call 
sendmail will instead have postfix handle the mail (seems like things 
work that way out-of-the-box with Centos which switched to postfix?).

If I only need an MTA to send local jobs (logwatch, cron, etc.) to a 
remote system (that is running a properly configured MTA), are my 
choices only sendmail or postfix, or is there something simpler?

thank you
