we've been using perdition as a pop3/pop3s/imap/imaps proxy for about
four years now, first with Debian Sarge package and now under Etch.
And throughout this time I've seen pop3s (and from the looks of it
the same happens with imaps) processes stuck in connect, like this:
16836 ? S 5:31 0 120 32179 2204 0.0 perdition.pop3s
28070 ? S 0:00 0 120 32311 1564 0.0 \_ perdition.pop3s: connect
7782 ? S 0:00 0 120 32311 1564 0.0 \_ perdition.pop3s: connect
24468 ? S 0:00 0 120 32311 1568 0.0 \_ perdition.pop3s: connect
14180 ? S 0:00 0 120 32311 1568 0.0 \_ perdition.pop3s: connect
13503 ? S 0:00 0 120 32311 1564 0.0 \_ perdition.pop3s: connect
They never die off, keep the connection open, there is no traffic and the
other end might be long gone. Last trace in the logs is always like this:
Feb 5 22:05:16 pp11 perdition: Connect: hi.mi.ts.u->220.127.116.11
It must be something related to the SSL'ness of these service, since I'm
not seeing this happening ever for imap/pop3. Alas a lot of people do use
TLS with those, so it's not a generic SSL issue. Maybe the master process
could kick a child handling connections in the head after "timeout"
seconds in connect state?
If more information is needed I can try to provide it, but note that with a
rate of roughly 35 pops per second I'm a bit weary to turn on
This may or may not be related to another SSL related issue, which will
be for the sake of making searches in the archive more likely to find good
keywords in a separate mail.

I'm sure this is a newbie-level question, but I can't find it clearly
answered in the docs or example configurations.
Assuming a single instance of Perdition is bound to multiple IP addresses,
can Perdition rewrite requests based solely on what IP address receives a
I'm replacing an old mail system where each domain has a separate IP
address, and there are multiple instances where folks have the same
username and password on different domains. Their mail clients are often
configure with a user name of 'bob' as opposed to 'bob(a)domain.com', so I
really need the IP address in addition to the username/password to figure
out where a connection should go.
I know I could get around this by having multiple instances of Perdition,
each bound to a separate IP address, but there are about 40 domains (and 40
IPs) involved in this process. If there's an easier way to do it, I'd love
to avoid having all those nearly-identical configuration files floating
around, waiting to confuse me.
