minute, what is the deal? Its super annoying. Can

Sounds like you need to check for incoming e-mail before sending outbound
e-mail. Some [old] mail servers will reuse the authentication (username and
password) used when connecting to the POP3 server (incoming messages) for
their SMTP server (outgoing messages), but usually there is a time limit as
to when you have authenticated to their POP3 server and when that
authentication expires when you then try to use their SMTP server.

There should be an option in your e-mail client to configure the order of
connecting to the mail servers. In OL2002, it is the "Log on to incoming
mail server before sending mail" option in the configuration of an e-mail
account. It is normally off which means Outlook will normally send e-mails
(SMTP) before trying to receive them (POP3). This allows you to send
yourself a message, or include yourself in the CC or BCC headers, and get
the copy of that e-mail on the same mail poll (if your SMTP and POP3 servers
are fast). Try enabling this option to reverse the order so you first
connect to their POP3 mail server and then follow with a connect to their
SMTP server.

Since you mention relaying, it is also possible that you are trying to use
your ISP's mail server without authenticating to it. That is, you are off
their network (i.e., off-domain), coming in from some other network, and
trying to use their mail server without ever authenticating that you
actually have an account with them to have permission to use their mail
server. If you are on domain1 and trying to use the mail server on domain2
then you have only authenticated to domain1 and you are just some joker from
domain2 trying to abuse domain1's mail server (by trying to relay mail
through it). You need to authenticate to domain1's mail server. So
configure your e-mail account to authenticate to domain1's SMTP server by
providing your domain1 account's username and password for the outgoing mail
server. Otherwise, make sure you are on domain1 (which authenticates you)
when you want to use domain1's mail servers.

Checking for e-mail once per minute is way too short. Some problems can
crop up when checking for new messages within such an overly short interval,
like not knowing that your prior session has terminated before you again try
to connect (and where only one connection at a time is permitted per IP
address for an account). Do you really get such an onslaught of messages
that dozens show up within just a minute? Change your poll interval to 5 or
10 minutes.
