Problems Sending Mail Via Dialup

[WarpGammon Director]

I use Outlook 2000 on my desktop and Outlook 2003 on my laptop. In
each case, I have it configured to send/receive mail from about a dozen
accounts on two different servers.

On my laptop, I am able to both send and receive mail when I am
connected via broadband, but only send when on dialup. I have noticed
this in hotels and at worksites. For example, when staying in a hotel,
if I dial in (I use AOL), I can receive mail but cannot send it.
However, if I decide to purchase the hotel's broadband option, I can
both send and receive. I found the same thing while working at a
client. I am staying at an apartment owned by the client where there
is no broadband, and at the apartment I cannot receive mail through
Outlook. However, in the office they connected me to an external
broadband connection (not the office network, as I think that would
have had outside access restrictions) and I could both send and
receive.

Any ideas?

There's no need to post the same question five times.

If Do you receive any error messages when you try to send? Sending issues
when changing networks are usually tied to proper authentication (or the
lack thereof) to the outgoing SMTP server. See if any of these articles

I didn't mean to post it five times. I had some problems - and I
thought I went in and deleted all the repeat postings.

Thanks for the help pages. I am guessing that my dialup ISP (AOL) is
blocking the outgoing mail. I'll check with them.
