Reprocessing sendmail failed messages

[Tim Traver]

Hi All,

ok, I know this isn't the right list, but I've already tried the 
sendmail group, and no response, so I'm hoping that there might be some 
sendmail gurus on this list that can help me...

After a temporary DNS outage, several machines that we run have email
messages on them that sendmail attempted to relay to our mail
cluster, but failed because they could not find the host name of the
server they were relaying to.

So, now, I have hundreds of messages in the clientmqueue directory that
are marked as having permanent fatal errors. The top of the d file
looks like this :

   ----- The following addresses had permanent fatal errors -----
i... at xxxxxxx.com
    (reason: 550 Host unknown)

   ----- Transcript of session follows -----
550 5.1.2 i... at xxxxxxxxx.com... Host unknown (Name server:
xxxx.xxxxxxxx.com: host not found)

I see that there are many of these message that are important, and
want to save and send them.

Is there a way to get sendmail to re-attempt to send these messages ? I
think it just ignores them right now because of those lines.

Any help would be greatly appreciated,

Tim.
