The macosxhints Forums - how to send mail?

It's not easy to get postfix working. As noted above, your ISP may be blocking mail that you try to send. To get this working you will probably have to edit the postfix configuration file: /etc/postfix/main.cf

Here are the lines that I added or modified in my main.cf file:

Code:

unknown_local_recipient_reject_code=550

alias_maps = hash:/etc/postfix/aliases

alias_database = hash:/etc/postfix/aliases

smtpd_sender_restrictions=check_sender_access hash:/etc/postfix/access

inet_interfaces=all

inet_protocols=all

message_size_limit=5000000

mailbox_size_limit=51200000 

mynetworks_style=subnet

##myorigin=mydomain.com

myhostname=mydomain.com

relayhost=smtp.myisp.com

local_recipient_maps=

luser_relay=myshortname

smtp_generic_maps = hash:/etc/postfix/generic

virtual_alias_maps = hash:/etc/postfix/virtual

Oddly, sometimes I have to comment out the "relayhost" line. My ISP is inconsistent about how it treats mail originating from a dynamic IP address.

Here's what the mail.log looks like when mail has been sent successfully:

Code:

Apr 29 08:46:50 Smooch postfix/smtp[7241]: 7D99B8232F8: to=<me@mac.com>, relay=smtp.myisp.com[2xx.xxx.xxx.xxx]:25, delay=4.3, delays=0.32/0.08/3.6/0.33, dsn=2.0.0, status=sent (250 ok:  Message 140916886 accepted)

Good luck. Every time Apple does an OS/X update things change and I have to tweek postfix to get it working again.

As for why someone would want to send e-mail from the command line: I use it in shell scripts to notify me by e-mail when tasks have been done. For example, I have Carbon Copy Cloner send me e-mail when a backup has been done.
