Postfix restart in Mac OS X 10.8 Mountain Lion

October 14, 2012 - 1:09pm - by admin

Actually it is no so easy to restart Postfix in Mac OS X 10.8 Mountain Lion like in Linux :-)

However you can restart Postfix by plist unload / reload:

sudo launchctl unload /System/Library/LaunchDaemons/org.postfix.master.plist

sudo launchctl load System/Library/LaunchDaemons/org.postfix.master.plist

By the way, if you have a problem with Postfix, look at this article: Cannot send mail in Mac OS X 10.8 Mountain Lion

Cannot send mail in Mac OS X 10.8 Mountain Lion

August 12, 2012 - 4:21pm - by admin

There is an error while sending mail in Mac OS X Mountain Lion 10.8:

send-mail: fatal: chdir /Library/Server/Mail/Data/spool: No such file or directory

To fix just run in terminal:

sudo mkdir -p /Library/Server/Mail/Data/spool

sudo /usr/sbin/postfix set-permissions

sudo /usr/sbin/postfix start

The solution also fixes an error in 10.8 where the fax service has stopped sending emails after the 10.8 upgrade.

Another Postfix Mac OS X issue solution can be found here: Mac OS, MySQL: No such file or directory (trying to connect via unix:///var/mysql/mysql.sock)

Uncaught exception 'Zend_Mail_Transport_Exception' with message 'Unable

November 24, 2011 - 8:17am - by admin

Error:

Fatal error: Uncaught exception 'Zend_Mail_Transport_Exception' with message 'Unable to send mail. ' in /.........../Zend/Zend/Mail/Transport/Sendmail.php:137

Postfix is running, PHP can connect to Postfix.

We have got In Apache error_log:

postdrop: warning: uid=48: File too large

FIX:

The default max message size for Postfix is 10240000 bytes. Thus we do:

% /usr/sbin/postconf -e message_size_limit=XXXXXXXXXXX

where XXXXXXXXXX is the new limit.

And then restart Postfix.

FYI: Related issues:

The the default value for a mailbox size according to Postfix is 51200000 bytes. It may be changed like this:

% postconf -e mailbox_size_limit=0

And then restart Postfix.

The settings for all the size related parameters (in main.cf) can be listed like this:

# postconf -d | grep size

Sample output:

berkeley_db_create_buffer_size = 16777216

berkeley_db_read_buffer_size = 131072

body_checks_size_limit = 51200

bounce_size_limit = 50000

header_size_limit = 102400

mailbox_size_limit = 51200000

message_size_limit = 10240000

Voila !
