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...
