Re: SMTP Blocks

Nonsense. You're now going to claim I should be running my domain's email only on port 587. This will effectively cut my domain off. My user population will only have outbound service. "Noone" will be trying to contact my MTA on 587, they'll be going in on the standard 25.

I for one do not think blocking TCP/25 in either direction is "reasonable network management." ISPs will try to claim their MTAs are somehow better than mine, but I don't agree. I'm not a spambot or zombie, I think if it weren't for the residential ToS, my MTA is perfectly legitimate.

I fail to see (except for the nebulous "network management clauses") how blocking SMTP or HTTP is any different than blocking Skype or BitTorrent, and therefore shouldn't be blocked or hampered at all.

I am inclined to agree with you, but "I for one" and myself for two probably won't pass muster. What does the industry generally do and (importantly) why do they do it?

I think enough ISPs block port 25 outgoing and enough mail administrators recommend doing so that ISPs would be able to defend an accusation of unlawful blocking as "reasonable network management."

actually id tell you to get a business class account for your business. 99% of home users have no need for their own mail server, and isp's can easyly claim SPAM controll for blocking use of mail and webservers on residential accounts.

as for smtp or http being different than skype or bittorrent thats a simple one for the isp's. skype isnt used to send spam, and theyd LOVE to kill off bittorrent if givin the chance.

im playing devils advocate here. id love to be able to run my own server from home, would save me a good chunk of change in hosting costs. but i all so understand why isp's block them on residential accounts. if i really wanted too i could get a business account and call it a day. and if that was cheaper than my hosting id do it.

As an 'access' provider, the electric company does not query the brand, model, or use of my clothes dryer.

If the original intention was to give everyone 'neutral access' to the Internet (similar to a utility, as some online have mentioned), it should be across all protocols and ports, not some for the 'rich business folks' and some for the 'little residential people'.

I'm not talking about speed tiers or 'extras' (like hosting, Static IP, rDNS, etc.) here, I'm talking specifically about access.

I think your concept of Skype not being used to send spam is incorrect. I get spam from any 'instant message' based service, including AIM, ICQ, MSN, etc. Skype isn't unique in this regard.

Bittorrent has a sufficient amount of 'illegal' activity and can generate havoc on a network. Why wouldn't 'reasonable network management' apply there?

I would expect the ratio of legal/illegal content flying around the Internet is somewhere in the ballpark of (or worse than) the ratio of ham/spam on Port 25.

No, but if you want to run a laundromat and you need the appropriate juice to power that many driers, you will be forced to get a commercial electric account.

Running a mail server should also require a business class account, as you are doing something that is more advanced than the average consumer needs, and therefore also should understand how to prevent the abuse of port 25 in the first place.
