How Linux comes with sending mail

The following is a script that detects the size of the log file (catalina.out):

#!/bin/bash#author:chris Chan#written for Check catalina.outsize=$ (du-m catalina.out| awk ' {print $} ') echo The size of the catalina.out is: $sizeif [$size-gt 19000]then rm-rf catalina.out echo "Warning, the catalina.out size of the test environment CMS has exceeded 18. 5G, has been deleted. " | Mail-s "Warning" [Email protected]else Exitfi

New Point of knowledge!

The way to send e-mail with the shell is simple, in the following format:

echo "Mail Content" |mail-s "Mail Header" Destination email address

But sometimes it can be an error, such as this phenomenon:

650) this.width=650; "src=" Https://s1.51cto.com/wyfs02/M00/8D/8F/wKioL1ihmEGwpPu-AAB9Nb9SX2M248.png "title=" 1.png "alt=" Wkiol1ihmegwppu-aab9nb9sx2m248.png "/>

Encounter such phenomenon do not panic, in fact, the Mail has been sent successfully, but the reason that there will be such an error, because the current mail service does not support IPv6, then we first #vim/etc/postfix/main.cf, the inside of the inet_ protocols = All modified to Inet_protocols = IPv4, then #/etc/init.d/postfix restart, just fine.

Effect

650) this.width=650; "src=" Https://s3.51cto.com/wyfs02/M00/8D/91/wKiom1ihmb6RuzTnAACUCXUvFqw821.png "title=" 1.png "alt=" Wkiom1ihmb6ruztnaacucxuvfqw821.png "/>
