i’m a little confused about my dns setup… i registered charles-x.com with dyndns.org, they handle my dns and mx records. i setup dns in 10.3.4 internally with the same domain name. do i need to setup dns records for that too? well, i did and now i noticed strange behavior with clamd and mail gets delayed. clamd used to selfcheck every hour and now seems to check when it wants to or when every i send or receive mail.
clamd.log :
Mon Jun 14 05:01:14 2004 -> Database correctly reloaded (21951 viruses)
Mon Jun 14 06:15:38 2004 -> SelfCheck: Database status OK.
Mon Jun 14 11:34:55 2004 -> SelfCheck: Database status OK.
Mon Jun 14 12:50:18 2004 -> SelfCheck: Database modification detected. Forcing reload.

Mon Jun 14 18:05:22 2004 -> Database correctly reloaded (21961 viruses)
Mon Jun 14 19:08:26 2004 -> SelfCheck: Database status OK.i was looking around on the apple lists and it seems that bad mx records and cause alot of problems. i would really love to figure this one out. can someone tell me if this looks okay to them?
this is what my dns looks like –
localhost.charles-x.com. IN A 127.0.0.1
server.charles-x.com. IN A 10.0.1.201
workstation1.charles-x.com. IN A 10.0.1.2
workstation2.charles-x.com. IN A 10.0.1.3
charles-x.com. IN MX 10 server.charles-x.com.;
; Aliases
;
mail.charles-x.com. IN CNAME server.charles-x.com.
http://www.charles-x.com. IN CNAME server.charles-x.com.
tibook.charles-x.com. IN CNAME workstation2.charles-x.com.June 15, 2004 at 3:32 am #358236iztechParticipantwhat are the mx record at dnydns for your zone?
from the looks of it you have too many cname
they say it is bad to have an mx record point to a cname.it should be…
domain.com mx 10 mail.domain.com
mail.domain.com A x.x.x.xnot
mail.domain.com CNAME mailserver.domain.com

i have freshclam check 6 times a day… i just find it a little odd that clamd stops checking and will start again when mail is sent or received.
i just changed the hostname in my amavisd.conf from server.charles-x.com to charles-x.com and i think that fixed it, i won’t know for a couple of hours.
i really just wanted to know if my mx record looked alright and if it was needed for my particular setup.
June 15, 2004 at 4:02 am #358240bustthisParticipantmy dns records at dyndns are:
charles-x.com – 20 mx2.mailhop.org
charles-x.com – 10 mx2.mailhop.orgi am very new at this dns stuff, but i thought i set it up so the mx points to an A record-
server.charles-x.com. IN A 10.0.1.201
charles-x.com. IN MX 10 server.charles-x.com.
mail.charles-x.com. IN CNAME server.charles-x.comand the cname was there so i could use “mail” instead of “server” – all of my ssl certs are mail.charles-x.com, so i’d like to keep that, but i don’t have another machine to add, until my g5 arrives!!!
would it make sense to do this:
server.charles-x.com. IN A 10.0.1.201
mail.charles-x.com IN A 10.0.1.201two A records for the same machine? i wouldn’t think so, but what do i know!
maybe i don’t have a clue 🙂 i think i need a good book – i just find it confusing with dyndns in the mix.
