[courier-users] Running Courier-IMAP through inetd ????
Hi there, I just installed courier-imap on a Redhat 6.2 machine using the 'authpam' authentication.. This seems to work just fine!!! I do though would like to ask help 1 question because I can't seem to find much in de documentation: The imap-server I installed will only be accessed by 2-3 client computers. Because of this I want to block all traffic from other computers by accepten only traffic by allowing the IP's from the specified clients Normally I run our private services (SSH, FTP) throught INETD which allows me to block traffic using the HOSTS.DENY and HOSTS.ALLOW file.. As far as I know this also prevents any security holes being used in server software like COURIER-IMAP/SSH/FTP because a client should first pass the 'IP' check of INETD before the 'server' software is started.. Is it possible to start Courier through INETD..? I now there is some extra load, but this isn't really a issue.. I tried to do this by adding the IMAPD executable to INETD.. This didn't seem to work for me.. (I could telnet to port 143, but my IMAP client can't seem to connect..) If this isn't possible, is it possible for me to only accept traffic from a few different hosts by changing to configuration files of IMAPD and running it as a standalone version? (How is it with security leaks in IMAPD, have there been found quite a lot..?) Thanks in advance..

[courier-users] ESMTP over SSL (again)
Hi, Posted this question a while ago, but didnt get anything back. I know its lame to keep reposting, but hoping that at least one person has got this working. If im being stupid, just say so, and Ill go away and do (yet more) reading Anyway, Ive got pop3/imap running over SSL, using my thawte certificate, and everything works alright. My problem is with esmtp over ssl. I installed the relevant emstpd.cnf and esmtpd.pem file, using the same settings as I did for the outgoing protocols above. But, I cant seem to get Outlook to play nice with it. From what I can understand, smtp over ssl is normally done over port 465, but here were using the STARTTLS extension, so the clients just connects to port 25. If I telnet into port 25, I get the following advertised; 250-AUTH LOGIN 250-AUTH=LOGIN X-NETSCAPE-HAS-BUGS 250-STARTTLS 250-XVERP=Courier 250-XEXDATA 250-XSECURITY=NONE,STARTTLS 250-PIPELINING 250-8BITMIME 250-SIZE 250 DSN Outlook barfs, telling me that my server reported an internal error, but I cant find anything in the server logs. All I see is the start of a smtp connection. I assume the problem is that Outlook isnt starting the session properly, and therefore isnt doing SSL, and hence, isnt authenticating but does anyone have any clues as to why? Or even if theres some tests I can run to get a little bit more debug info. Oh, and just to confirm, I dont need a emtpd-ssl config file do I ? Thanks, Bryan.
RE: [courier-users] ESMTP over SSL (again)
Thanks Mike, Outlook works alright with my esmtp server, as long as I tell it not to bother with SSL, so I think it can handle the multi-line greeting alright. Similarly, it can handle the secure connections thru pop3/imap, so I assume theres not a problem there. I think its got something to do with my esmtp config. Pop3/imap over ssl have their own port, so I think thats more straight forward. Thanks for the offer of letting me try it with your server, but I think I would really need someone who has SSL running, just to prove that its my courier-mta config thats broken.

You may need to rebuild the machine, for some reason. 2. anyone have any idea (before I put this online) how effective the 'require authorization' option is at stopping spam? It would be wise for you to actually read what that option does, instead of speculating. The only reference I could find among the somewhat scattered documentation was http://www.courier-mta.org/install.html#esmtpauth which tells me that an auth step (in my case PAM) similar to that used to check mail is performed before sending mail. Seems like that would make it harder for my smtp to be used as an unauthorized relay. Right. Except that nobody will be able to send you any mail, since it is unlikely that every other mail relay in the world knows the userid and password for your mail server. This option is designed to be used on port 587 only, the message submission protocol, which requires authentication. -- Sam ___ courier-users mailing list [EMAIL PROTECTED] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users

[courier-users] Attachment filtering
Hi Is it possible to have courier remove attachments such as exe, com, bat, url, etc on incoming mail, as well as, indicate in the message that the attachment was removed? I've noticed the attachment name is defined twice in the email: in the name attribute of the content-type and in the filename attribute of the content-disposition. Which one of these should be filtered? Should the mime value of the content-type also be used in filtering?

[courier-users] SMTP slowly driving me mad
I've spent the past three hours trying to figure out this problem, which is well on it's way to ruining my weekend. For some reasons which I have not been able to figure out, and as of this writing have not seen in the archives, SMTP is hanging upon connect. This is a brand new install of 0.37.2 on FBSD 4.5. So far I've tried disabling DNS lookups, turning off various auth modules, and rebuilding from scratch with --without-authmysql since MySQL is installed on this machine. A connection attempt to port 25 is made, but then there is no SMTP banner and it will sit like that until the end of time. I'd appreciate some insight on to what else I should take a look at to get this working so that I don't have to resort to backup shells to send receive mail. ___ courier-users mailing list [EMAIL PROTECTED] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users

[courier-users] [dev] what's webmail doing?
Hi All, I'm trying to get sqwebmail to run basically behind my own CGI server (actually, it's an addon to Zope), and running into a wierd problem. The thing is basically working, you can log in, and look at the 'folders' view, but it hangs when trying the other views (like preferences or create message). The way this CGI server works is by using os.popen3 (in Python) to run the webmail script, after setting up the proper (I hope!) CGI environment. It's working, and I can see that the child process sets it's owner to whoever I log in as, so it looks like it's working (well, yes, it's working, because it properly shows the folder list for that user. Also the same CGI interface is working great with the webadmin script). I'm wondering why does it hang when, e.g. clicking on 'preferences'? 'folders' is the only navbar choice that seems to work. I've been looking thru the source, but I don't see what could be the problem. Any ideas what it could be doing that would cause os.popen3 to hang? Maybe trying to open some file or fork something? I've been on this for days ___ courier-users mailing list [EMAIL PROTECTED] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
