This actually also involves irc.mod.

I have seen user to struggle with finding the optimum settings and it was often
necessary to patch modes.c and server.c to support new modes. I believe I read
somewhere it was unreliable, but everywhere I connected and checked the
settings, they were pretty much correct. You can learn very much from these
strings. And if you believe some server versions might screw up you have 2
options: user overrides settings in eggdrop.conf, an exception is handled
parsing RAW 004 which contains the server version.

Here are a few examples I collected together for a few server version I believe
to be popular, so you don't have to research on your own. The server version in
() are taken from RAW 004 code. I hope rizons Hybrid patch isn't mature, I
haven't found another server running it atm..
I used PuTTY in RAW protocol as client to be sure to receive raw data:

Comment by @Robby-
Please do make this configurable (enable/disable) though, as in some IRCd server software the info in raw 005 is not totally reliable. I'm on such a server (inspircd 1.2.8) which for example has MODES=2 and yet I can set 4 modes at a time, also MAXBANS=60 and yet I can set up to 1000+ (really, I tested it). So, the info in there is actually not so reliable unfortunately, and so the need/possibility to set the individual settings (like it's possible now) should continue to exist.

I'm shocked but not entirely surprised such a misconfigured network/ircd exists. You should hunt down the adminstrators of it and yell at them 24/7 if it in fact behaves as you described. It's planned to give options to override raw005 information on a keyword basis, so you could tell eggdrop that it's really MODES=4 and BANLIST=1000. It's not planned to make it possible to disable that feature as a whole though, because it's intended to get rid of config variables.

This is not really misconfiguration, I'm an IRC operator there and have close contact with the administrators. This seems to be a bug in the ircd itself, hence me saying that the info in RAW 005 isn't totally reliable. Good to know it will be possible to override that. :)

It has to be reliable. Hunt down the developers of this software and make them fix it. Providing incorrect information in 005 is terrible.
