Re: [otrs] SMTP Woes

Great you have it working now. Basically, it's because of the reason why the exchange admin had to put you on a whitelist in order to send email. SMTP is a pretty old protocol and, if you have a port 25 smtp service, does not do any encryption. The old style SMTP does not even do authentication, which means anyone can use the SMTP service to send out mail. So spammers could use any SMTP server to send out tons of messages. Therefore SMTP servers usually are configured to only accept data from the local subnet, meaning that only PCs within the Town of Vernon can deliver mail to the local SMTP server. No password is needed, and mail is just sent out. Services like Google mail use encryption and authentication; they accept mail originating from any PC, as long as it can authenticate using a valid username and password (authentication). If they would not use encryption; the username and password can be intercepted by anyone listening to the packets on the internet, because they would be plain text. The communication for encrypted SMTP (also referred to as Secure SMTP or SMTP over SSL) usually uses ports 465 or 587. Modern MS Exchange versions (2007 and 2010) have the old, 'port 25' smtp service disabled by default, and usually only accept mail via secure ports. Of course you can still configure them to accept plain text smtp for backwards compatibility, but at least they have safe defaults. good luck with your first steps with OTRS and ((enjoy))! -- Michiel Beijen R&D OTRS AG Norsk-Data-Str 1. 61352 Bad Homburg Germany T: +31 (0) 6457 42418 F: +49 (0) 9421 56818-18 I: http://www.otrs.com/ Business location: Bad Homburg, Country Court: Bad Homburg, HRB 10751, VAT ID: DE256610065 Chairman: Burchard Steinbild, Managing Board: André Mindermann CU@ CeBIT 2010 in Hannover (Germany) and get to know more about OTRS at booth no.

You guys are all fantastic.  That was it, I took out my user name and password and it worked just fine.  How does that work?

Thanks, Justin Holt

But if you're using port 25 on Exchange, it's most probable that you're running into issue because you ARE supplying a username/password in your Core::Postmaster configuration.

I think you wanted to pint to Framework -> Core::Sendmail, right? :-) Nils Leideck

Sure, of course I wanted that.... :D -- Michiel Beijen R&D
