IP addresses and email reliability

[eva]

hi, i'm still looking into buying a reseller plan here, but in reading the forum posts i see recurring problems with email reliability which really concern me. (for example: http://forums.hostnine.com/showthread.php?t=970). it seems the problem usually results from one customer abusing the server by spamming and that shared IP address for all users on that server becoming blacklisted. if that is correct then wouldn't my best defense against this problem would be to have my own dedicated IP addresses to be shared only amongst my own domains? since i am not planning to spam or cause any abuse then wouldn't i be immune to the problems caused by the others?

if the above supposition is correct then could i use the the 2 free IP addresses offered for my domains rather than for private nameservers? or will you let me puchase a dedicated IP for this purpose? i would much prefer to have reliability for my web sites and email than use custom nameservers or having my sites distributed amongst different servers. my plans for reseller hosting are to host my own sites and only friends and friends of friends so i know abuse won't occur. this is the web hosting niche i want to do.

any insight on this would be appreciated because the spam blacklisting issue seriously bothers me since it appears i have no control in preventing it. it also seems to me that resellers should have dedicated IP addresses anyways since they are web hosts and not a shared host. more professional.

thx,
eva

a dedicated ip isn't going to help. The outgoing email server is the host that you end up on - mine was crater for most of my sites. So, mail being sent from
you@yourdomain.tld ends up coming from crater.com (or org or what ever it was).

The only solution that was posted for me was a dedicated server where I controlled who was on it. For my 'charity' sites that I run, that is simply not an option.

Those here that can add a SPF record might try one like this as I have been using this with fairly low rejection rate

"v=spf1 a mx ptr include:server_name.myserverhosts.com ?all"

Where server_name is the server you are on
