Re: [cobalt-users] smtp not working properly.

[Jeff Lasman <jblists@xxxxxxxxxxxxx>]

Two issues; mentioned (perhaps) by others, but maybe not clearly enough...

1)  Don't rely on Outlook Express "Requires Authentication" to do it by POP 
before SMTP unless you know it does it that way; my guess (I do NOT use 
Outlook Express) is that it doesn't.  Instead actually do a POP to get your 
mail.  I'm not 100% positive, but I believe if you just press "send and 
receive" twice, it'll fail to send email the first time but succeed the 
second time if in fact you've got POP before SMTP set up on your server and 
issue 2 (below) isn't an issue for you.

2)  Many ISPs are now blocking outgoing traffic on port 25.  More are 
adding it literally every day.  Many ISPs THINK (emphasis mine) that this 
helps eliminate spam, which it doesn't.  I see this issue every day, 
because we're American distributors for a Windows-based mail server often 
used by small customers over dialup connections <www.mailtraqna.com>.  If 
the customer's ISP is blocking traffic on port 25 he has five choices:
  1.  Convince the ISP to unblock it for him
  2.  Use the ISPs mail server
      a. problem:  doesn't always work; some ISPs don't
         let you send out mail from their server unless
         your return address is set to their domain; a
         few even change your return address to whatever
         you've logged in as <frown>).
  3.  Find another ISP, who will allow outgoing mail on
      Port 25.
      a. problem:  this is getting harder every day as
         more and more ISPs are blocking such traffic
  4.  Get a direct connection without port blocking
      a. problem:  this costs more than many people
         are willing to pay.
  5.  Use your ISPs mail server, give up on using
      your own domain in your "From:" header, but
      use it in your "Reply-To:" header.

I hope this helps <smile>.
