My brother in law works for a company that has an admin that simply won't change the current server to use ssl or even simply a different port than 25. so naturally when he is home or on the road, 80-90% of the ISPs will block 25,and he can't send outbound email. Right now he is using an ATT account with his home service that allows him to add his work email to the "list" of email domains he can send from using his att login information.
He took advantage of faster cable internet with Charter as well as cheaper, and it turns out charter only allows you to send email as firstname.lastname@example.org. If you use their smtp, it does send, but no matter what you do, the "from email" address is always the charter.net account.
So anyone where to do this with charter or have a recommendation for a paid service that will do this? Volume is regular business use, so I would guess 150-200 a day, give or take 4k-5k a month, no news letters, just regular mail correspondence.
