Who is their provider...meaning who do they connect
to for their internet access? Many of the larger providers are now blocking
outbound SMTP to any mail server they do not operate. If you don't see them
connecting in your log, have try to telnet to port 25 from a command prompt on
their machine..
>>telnet <your.i.p.address>
25

The only SMTP entries are:
08:23 01:28 SMTPD(029501CA)
[61.171.181.41] RCPT TO: <[EMAIL PROTECTED]>
They
receive email just fine. Just can't send it.

Mark,
POP3 is a
"retrieval" protocol and has nothing to do with the standard sending of
mail. What do the SMTP logs show for this user?

- I currently have 8.05 fully patched on a win2k server. We have a
Sonicwall Pro 330 firewall with cisco routers and switches. We get
our bandwidth from Sprint, and MCI.
- For some time I have experienced an intermittent problem with some,
not all, of my clients being able to access pop3 from their client
programs (outlooks).
- They typically can receive email but cannot send email.
- This will happen to 2 or 3 of my client domains that reside on my
server.
- This is the entry for one of our clients today that nobody in their
office can send email via the client.
08:23 11:46 POP3D (00000570) logon success for sashwill
- mail.somecompany.com from xx.xxx.xxx.xxx
- 08:23 11:46 POP3D (00000570) logoff for sashwill R:0, D:0, P:0
- This is the entire entry for this persons attempt to send an email to
me on the server.
- I do not have their IP listed in SMTP security and do not want
to.
- I had another client early in the morning with the same problem.
I rebooted the server and their problems cleared up but this client is
still having the problem.
- Has anybody else seen problems like this and if so what solution was
found if any?
- Since this is only happening upon occasion I am inclined to believe
the problem is somewhere outside our network. Also since it doesn't
impact our clients severely I have ignored the problem for the most
part.
- We will be upgrading to the latest version soon and I wanted to at
least find out where the problem is coming from.
