Speaking on Deep Background, the Press Secretary whispered:
Okay, the main difference seems to be: 1. People here trust, that mailservers on port 587 will have better configurations than mailservers on port 25 have today. I do not share this positive attitude.
Well, is authenticated SMTP 587 going to be worse than open port 25? I doubt it, but... In fact, I think most folks will do way better. Call that blind faith in the inhabitants of Middle Earth ^H^H^H NANOG....
2. Port 587 Mailservers only make sense, when other Providers block port 25. My point is: If my ISP blocks any outgoing port, he is no longer an ISP I will buy service from. Therefore I do not need a 587-Mailserver, as I do not use any ISP with Port 25-Blocking for connecting my sites or users.
So you will choose hotels, conferences, etc, by whether or not they block 25? And coming soon.. airlines! "That's right: aisle seat, low-sodium meal and NO port 25 blocking..." I do well to find out if the above has access at all, esp. if dealing through a reseller [hotels.com, etc]. -- A host is a host from coast to coast.................wb8foz () nrk com & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433
