How do I get sendmail to work reliably on Mac OS 10.5?
I need to use sendmail from Mac computers in the office. At the moment I can get it to work on two development masks (which I think has to do with the fact that MAMP is installed and running), but getting it to work on others seems to be a problem ...
I'm guessing there are some configuration issues, and I hope I can fix it somewhere (without having to install MAMP on every machine!).
I think it might be "local" in nature, but not sure. Here's a dump of /var/log/mail.log if it helps:

Note that this is a postfix you have running on your mac, not sendmail.
The problem is that machine mx01.xxx.uk [212.xx134] is configured to block mail relay (accepting e-mail via SMTP and sending it to the destination mail server). Postfix configuration files are usually stored in / etc / postfix, so you can start looking there. Specifically take a look at the mynetworks setting in main.cf.

Aha! Thanks to Denis - it looks like bliss ...
### MAMP Postfix Configuration - Start ###
myorigin = example.com
myhostname = mailer.$myorigin
smtpd_sender_restrictions = permit_inet_interfaces
# smart host
relayhost = auth.example.co.uk
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_MAMP_passwd
smtp_sasl_security_options = noanonymous
### MAMP Postfix Configuration - End ###
# DONT REMOVE: MAMP PRO main.cf template compatibility version: 1
I will give it and return to you.
