I won't argue too strongly on this (though I should because I *have* configured sendmail systems and its just not that hard, if you're a developer. And I have rolled my own Perl scripts that talked enough SMTP to connect directly, so its not that big a deal, again for a developer), but my point was that the arguments that said "don't use sendmail, it won't get through firewalls that block port 25" are just wrong.
Now, if someone had said "Apple's default firewall only lets Mail.app connect out through port 25", I'd have gone home and taken a look because I wasn't aware of that capability being in the box. That's why I use Little Snitch. The points being made about some users not having an SMTP-able email server is quite valid. Though people using gmail can still do smtp, as far as I'm aware. http://lifehacker.com/software/email-apps/how-to-use-gmail-as-your-smtp-server-111166.php -----Original Message----- From: Andrew Farmer [mailto:andf...@gmail.com] Sent: Wednesday, 24 June 2009 3:27 PM To: Jeff Laing Cc: Nick Zitzmann; cocoa-dev@lists.apple.com Subject: Re: Cocoa and email (SMTP/POP3) On 23 Jun 2009, at 21:52, Jeff Laing wrote: > Ok, I'll bite. > > How does the mail server that Mail.app is talking to distinguish > between Mail.app and /usr/sbin/sendmail ? They both presumably just > talk SMTP ? Mail.app is configurable by the user to connect to a specific relay mail server, potentially using login credentials, SSL, and/or an alternate port. Sendmail, by contrast, is not configurable (without cracking open the terminal, at least), and will by default always connect directly to the destination mail server. It's this exact behavior that makes it unlikely to work properly. Consider also that not all users even have Mail.app configured. An increasing number of users use online mail services such as GMail exclusively. In their case, not even scripting Mail.app will help you. If you really need to deliver email notifications from an application, the only reliable solution is to put together a properly secured web- to-email gateway for your application somewhere and use that. Sending email directly from the desktop is no longer a viable solution without explicit configuration. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
