Description Andrew Meredith 2000-06-02 20:24:08 EDT

Hi There,

If your mailer does remote sync (eg netscrape) which involved going into a 
large number of IMAP folders saying "Anthing new?" and exiting if the 
answer is no, then inetd sees this as looping and issues:

inetd[572]: imap/tcp server failing (looping), service terminated 

It then bounces all further connections to port 143.

Can anything be done to alleviate this. This is either a documentation 
problem or a mismatch between the 3 components netscape, inetd & imapd. 
The are all doing what they are supposed to do, but the overall function 
of syncing mail across a number of frequently un-updated mail folders 
fails.

Cheers

Andy M

This is a feature, not a bug. Add a maximum rate in /etc/inetd.conf like
    imap    stream  tcp     nowait.<MAX>  root    /usr/sbin/tcpd imapd
where <MAX> is the number of permitted spawns per scond (default per man
page is 40)

Oops ... didn't spot this in the man pages .. mea culpa.

<pathetic excuse>

The description of the optional .max parameter was tucked away as the last 
sentence in a paragraph mostly about UDP packet management.

Maybe a para break in the man pages ??

</pathetic excuse>
