I'm getting an error message that says it can not connect to 10.0.0.241 (our exchange server). I just talked to our head tech and he pointed out how we don't have port 25 open to anyone, otherwise we'd open ourselves to a crazy amount of spam. Instead I'd have to add the OTRS server to the SMTP connections and relays list. This looks promising now considering I can telnet on 25 (basic test of smtp). But now I get a " No SASL mechanism found at C:/Program Files/OTRS/OTRS/bin/cgi-bin/../../Kernel/cpan-lib/Authen/SASL.pm line 74 " error. Is it because I don't have some perl module installed?

Hi Justin,

What kind of error messages are you getting when trying to configure OTRS for SMTP via Exchange? What is posted in the OTRS syslog? What are your configuration settings in Core::Sendmail?

Hi all, I'm trying to set up customer notifications with OTRS 2.4.5 on Windows Server 2003 (fully updated). The Domain Controller is on a separate server, and the Exchange 2003 is another separate server. This is probably an issue I'll have to take up with my boss (I'm a lowly college intern), but for some reason SMTP and our Exchange server just refuse to cooperate. But, if I use my GMail credentials and tie it to Google's servers, it works just fine. I would use GMail, but my other boss says that would be a little too kludgy, and would make the town administrators next door upset if they found out (town politics are a mess).

Thanks for all your help as always! Justin Holt Town of Vernon IT Intern

Hi Justin, You're **supposed** to have all the packages you'll need for running OTRS, including the SSL modules. 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. If you do that, OTRS will supply them, if your exchange server expects them or not. Leave them out and see what happens. Usually you'd only need SSL modules if you select SMTPS as a mail send backend but then you're also no longer using port 587 or 465.... in this case, it SOUNDS like you should be good by simply checking port 25, SMTP, and NO user/pass. hth, -- 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.

It seems as if there are perl modules I'm missing (IO::Socket::SSL from what it looks, among others). I tried to use cpan to install all of these, but it seems under windows I'm coming up against some barriers. Every package I try to install always fails.  Is this a problem with Strawberry Perl or is it something else I need to install to get this to work right?

Thanks, Justin Holt

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.
