smtp/outgoing mail

iroc409 · 02-18-2004, 03:52 AM

i think i'm in need of setting up an smtp server for my outgoing email, half the emails i sent out last week don't seem to be getting to where they're supposed to go, and it's EXTREMELY frustrating. in fact, i'm probably losing out on some good $$ because of it (not to mention angrifying a few people). the worst part is, i don't have any sort of notification that my emails aren't going through.

unfortunately, my isp blocks all smtp servers except their own, so i can't use any of my hosted servers for outgoing. i'm hoping, however that if i set up a local server, all would be well.

but, can i set up an smtp that will work properly on an internal lan? i'm running a dchp router since i only have 1 ip, so the machine would have to be internal on this network. i'm thinking it should be ok, because it really only needs outbound communications, i don't need to recieve anything (but am somewhat concerned with the server's interactivity with dns and mx records). i used to have a box running sendmail on a static ip, and that worked fine for send/recieve (from that box only). i even tried once using a basic rh box as an outgoing server (on a dynamic internal address), and the mail sent just fine (although it stated the sender as the box owner's address/name, so i need to make sure that doesn't happen - i have multiple accounts all serving different purposes, and they sent mail needs to reflect that).

anyways, i figure i'd just use sendmail for this, but i just had some concerns. any enlightenment, tips, or better solutions you folks have i'd appreciate. i think everything will work, i just need to make sure it does

oh yeah, also, are there any issues with spam filters or hosts on the recieving end rejecting my emails if i set up this way? not that i won't be using completely legitimate email addresses & return addresses, but just worried that they may be filtered due to a somewhat 'unknown' origin...

I think many email providers (such as hotmail, yahoo, etc...) actually block small SMTP host like this. They do that because alot of spam are sent out through 3rd party computers with unregisterd smtp servers. But im not 100% sure, I just tryed to do a smtp server 6 or so months ago, and I remember reading that somewhere.

hrm. that's kinda what i thought. although, i didn't seem to have _too_ much of a problem a few years back running a mail server on a subdomain when i had my biz line... although the subdomain i was on probably wouldn't flag it as necessarily bad, and i generally only used it for people i knew and stuff.
