AmiExpress and DayDream were popular on later days and on telnet age, at least on scene boards. And probably the newest BBS software which gained use was F.A.M.E. (Final Amiga Mailbox Engine). It has been released as freeware nowadays.
As for terminal programs.. I made my first tries with JR-Comm, but I started the real use with Term and later moved to NComm (which is freeware nowadays too). On telnet age I've been using DCTelnet.
