Hi all, (I've sent this to newbie and this one because I am not sure which it would come under) My sendmail is getting this message in /var/log/mail/warnings... Jun 22 01:24:25 mail sendmail[1678]: gethostbyaddr(203.46.23.49) failed: 1 I get a similiar message when I do a Makefile for a perl module and some other stuff,,,,, Does anyone know what that means??? I have suddenly stopped getting my mail as well... nothing from this list in 2 days...or any of the others I am on. but if I use my hotmail account to send my server an email, it receives and passes it along to me just fine.. I don't get it, how come hotmail can send me an email, but most others cannot? sendmail reastarts with no error messages.. so I am lost as to why this is happening.. also, if I log onto the box and use pine to send myself an email, it works as well... is the message because my servers firewall stops icmp???? anyone have any suggestions about that or the error message above...?? if you do, can you cc a copy to [EMAIL PROTECTED] ??? so I can get it? many thanks... regards Frank
