Which service?

It appears that, at least for some protocols, this message is the result 
of limits hard coded into libpurple.  As Yahoo has been mentioned in 
this context, recently, it looks like, at least in that case, the code 
is representing the service provider's documented limit, moderated by 
the result of tests.

Emails are not formal business letters, whatever businesses may want.
RFC1855 says there should be an address here, but, in a world of spam,
that is no longer good advice, as archive address hiding may not work.
