Anonymous Relay and ISP's and how they effect mail handling.
Posted Jun 4, 2007 @ 1:23 pm, Viewed by 436 Visitors, Read 440 Times.
Folks,
I have been fielding a lot of e-mail send/receive problems as of late and I wanted to let you all know the fix.
When you are hosted with Real Estate Webmasters you get mail hosting for free on our servers.
The problem with that is that over a year ago a large-scale spam attack caused many ISP's to deny anonymous relay of mail.
So, to still send and receive mail you will have to first know who gives you your connection to the internet.
In the case of a Cox.net customer I have, we made his outgoing SMTP to smtp.east.cox.net
Another customer of mine uses qwest and set their SMTP to smtp.phnx.qwest.com
Keep in mind you do have to make sure you authenticate yourself on their servers by setting the Outgoing server to use the Incoming servers login credentials.
See the screenshot below:
That is the easy part.
The hard part is knowing what ISP you are using while you are traveling between offices or client locations.
In this case your e-mail browser (Outlook 2003, Thunderbird, etc) may not be the best choice unless you set up multiple identities using the same incoming credentials but all the different ISP setups for outgoing servers in your area.
Alternately, you could use the webmail console.
If this instruction leaves you confused, e-mail me and I will be happy to assist.

Hey Thomas, I sometimes get customers send me this error. 553 sorry, that domain isn't in my list of allowed rcpthosts Does this mean that they need to set their outgoing mail server to their ISP's outgoing SMTP?
