Hah... too bad in my industry, incompetence is pretty common. And the more incompetent, the more likely you are to be promoted. So the most incompetent ones are the ones I can't afford to ignore. ;) > With TMDA you can use the tmda-pending utility to show a list of > messages which are unconfirmed.

If I don't want to make people reply to confirmation messages, I could simply run a whitelist by default, /dev/null all the blacklisted items, and inspect the "purgatory" spool once a week or so to update both lists. -Chuck

(Yeah, it happens!!) With TMDA you can use the tmda-pending utility to show a list of messages which are unconfirmed. Some people seem to like having cron send them a daily list of messages in the unconfirmed list. (or, perhaps a list of new messages in the pending directory...) So, it's not like you never get the chance to see the message. You can look in the list and say, oh...release that message for me.

Redundant Mail....

by wlug＠beakerware.net

I couldn't think of a better way of phrasing it. I'm running Courier for incoming SMTP, POP3, IMAP, and webmail. The mail itself is stored using Maildirs in user's home directory. Short of running something like rsync between my primary box and backup, is their any good way of getting redundancy into the picture here? I already have the backup box setup as a relay in case the primary goes down, but that doesn't make the mail any closer to the user.... -mike

As it is now, my junk is routed to a junk spool that I check on a somewhat-weekly basis, just to make sure I didn't accidentally junk a message from a potential customer, or other business contact that's just lame enough to send a spam-looking message from his Yahoo account. (Yeah, it happens!!) Spamassassin looks cool, but I don't admin the machine where my mail is processed, so it may be a while before I can set that up. ;) (It's actually a Redhat 5.1 system that hasn't been touched since Redhat 5.1 was brand new. We've only installed security upgrades.) But I did find mention of ordb.org on the spamassassin web site, which has solved my immediate problem. ;) > > BTW, for the curious, my daily haul of junk mail varies from 20 to > > 40 messages.

I have SuSE 7.2 and I get a response to ipchains -L but not to iptables -L :-) (uname -r gives 2.4.4-4GB) SuSE supplies two firewalls, a personal one (a quickie, basically just masquerading) and "SuSE firewall". The latter is configured via a file /etc/rc.config.d/firewall.rc.config which has this line Note: For 2.4 kernels, you need to have ipchains support enabled. in the comments section. So Chuck's instincts seem well-based. In SuSE's defense, this is back at 2.4.4 kernel which, I gather, was not quite ready for prime time even with the ipchains modules. Also SuSe does not claim to hand-hold for firewall stuff; you have to pay extra for that >-) doug PS My spell-checker thinks "firewall" might be "fireball" :-)

I would think the firewall would only timeout connections which are being masq'd and run through connection tracking...and in that case, I thought the default timeout was pretty high. try iptables -t nat -L to see what's going on there. -- Josh Huber
