There is also a deferred queue to ajust in the /etc/sendmail.cf: O Timeout.hoststatus=30m --- Trond -----Original Message----- From: Rolf Krahl [mailto:rolf@math.uni-bremen.de] Sent: 29. juli 2003 16:59 To: suse-security@suse.com Subject: Re: [suse-security] Re: Problems with a Mail Server and SuSEfirewall2 On Tue, 29 Jul 2003, remote wrote:

Sometimes this is not possible and the mail is saved in a queue. Check the SENDMAIL_ARGS parameter in /etc/sysconfig/sendmail for something like "-q30m".

You were right, "-q30m" ist given as an argument in /etc/sysconfig/sendmail. So, does this argument reroute outgoing mail if there is a problem with the ISP`s mail server ? If so, what can I do to flush the resulting queue from time to time, say once a week ?

This is just what "-q..." is for. The argument "-q30m" tells sendmail to flush the queue every 30 minutes (e.g. look for mail, that have been queued for some reason or another and retry to send any message found in the queue). So, if this argument was actually given to sendmail before the reboot, then its strange, that you didn't see any try to send the mail. sendmail (in the usual configuration) would have send a warning to the sender if it still failed to send the message after a couple of hours and would have given up to send the message after some days. But this only happens while sendmail tries to resend the message, so if your users didn't see any warning about problems to send mail, it's likely that sendmail actually did not retry to send the mail. (Check your logs!) So maybe, due to some problem, that i'm unable to analyse from here, the "-q30m" didn't make its way to sendmail's command line, although it was given in /etc/sysconfig/sendmail? -- Rolf Krahl <rolf.krahl@gmx.net> -- Check the headers for your unsubscription address For additional commands, e-mail: suse-security-help@suse.com Security-related bug reports go to security@suse.de, not here
