Google has not helped much, but again I may be searching using > wrong keyword. 1.) you can use the courier-suites own tcp server (quite similar to the DJB tcp server), 'couriertcpd' - look into the manpage, it is able to do ip restrictions and much more. 2.) dont know if it is possible to compile courier imap aginst libwrap and use the tcp wrapper (hosts.allow). 3.) i would not start courier imap via inetd/xinetd - courier imap was developed to be a stanalone imap daemon running within the courier-suite/framework...sure, you could use tcp wrapper without probs when using inetd/xinetd but there are better solutions than using one of the "super servers" *urghh*. 4.) use the packet filter on your border router/gateway/firewall or firewall the host directly via ipfw/ipf/pf to restrict access. > > > -Wash > > http://www.netmeister.org/news/learn2quote.html > > -- > +======================================================================+ > |\ _,,,---,,_ | Odhiambo Washington <wash@wananchi.com> > Zzz /,`.-'`' -. ;-;;,_ | Wananchi Online Ltd. www.wananchi.com > |,4- ) )-,_. ,\ ( `'-'| Tel: +254 20 313985-9 +254 20 313922 > '---''(_/--' `-'\_) | GSM: +254 722 743223 +254 733 744121 > +======================================================================+ > Pohl's law: > Nothing is so good that somebody, somewhere, will not hate it. > _______________________________________________ > freebsd-isp@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-isp > To unsubscribe, send any mail to "freebsd-isp-unsubscribe@freebsd.org" > > !DSPAM:42666ca8698371595919483! > -- mfg. christian damm technische leitung phone: dw 42 email: christian.damm@diewebmaster.at icq at work: 124464652 die webmaster - flötzerweg 156 - 4030 linz - austria phone: +43-732-381242 fax: +43-732-381242-22 isdn (leonardo): +43-732-381242-33 homepage: www.diewebmaster.at, public email: office@diewebmaster.at
