The client *DOES* now the maximium MMS, so if it's per-conversation, it
works.
If a message is too long, it's silently dropped by the ICQ gateway.
This is really bad behaviour anyway, but all gateways seem to handle
it like this. The max. MSS seems to be really small on ICQ without
direct connections. And I don't know of any ICQ gateway taht uses direct
connections.
