E-mail - MSA / Alternate port SMTP service.
Many ISPs (access providers) are blocking access to SMTP servers
outside their networks. As far as we know, the goal is to stop
spammers from signing up for "throw away" accounts, and sending mail
through open and/or anonymous relays. Unfortunately it also blocks
access to our SMTP servers, and thus the ability for you (our client)
to send mail.
The solution to this problem, is for us to run an SMTP server on a
different port. (Our servers will only relay for known senders, so this
not defeating the purpose of the block.)
Using the alternate port service (MSA).
This should be easy. Somewhere in your e-mail client there should be a
setting for the SMTP server name, and a port. The normal/default port
is 25. The alternate port service is port 587. (587 is the message
submission agent [MSA].)
The MSA port uses two methods of deciding
(POP-before-SMTP and SMTP-AUTH) if you are allowed to
send outbound mail through the server.
POP-before-SMTP is simple to use, you just need to check your mail before
sending mail... the mail server will remember your IP address for more than
an hour and allow you to send outbound mail.
SMTP-AUTH (smtp authentication)
SMTP-AUTH is somewhat different. Your e-mail client will send a userid and
password to the mail server. The mail server will allow you to send
outbound e-mail if they are valid. There is no requirement to check your
mail first. Unfortunately, TLS / SSL is not currently supported.
To use SMTP AUTH, you need to configure
your mail program to authenticate using your full email address
(userid@domain) instead of just your userid. The POP and IMAP servers
also support that syntax, so it is probably simplest to reconfigure
your e-mail client to use userid@domain instead of just userid.
(For example: instead of logging into the baremetal.com POP server as
support, we would login as support@baremetal.com
[still specifying the POP server as baremetal.com]).
Instructions for specific E-mail clients.
Hopefully the instructions for your email client are below. Unfortunately
time and software moves on, so the better written descriptions are out of date.
For Microsoft Outlook:
Tools -> Email Accounts
Put a dot in 'View or Change existing e-mail accounts' and click Next.
Select the account having problems and click 'Change...'

Click Okay, Next, and then Finish
For Thunderbird:
Tools -> Account Settings...
In the left side, click on 'Outgoing Server (SMTP)'
On the right side, click on the Edit button for your Baremetal account.
Change port 25 to 587.
Click Okay, then Okay again.
For Eudora 7:
Tools -> Options...
In the left column click on 'Sending Mail'
Ensure the 'SMTP server' is your Baremetal hosted domain.
Check 'Use Submission port'
Click Okay.
For Eudora 6:
Changing the SMTP port in Eudora version 6..
For Outlook Express/Outlook 2000:
Change the SMTP port in Outlook Express/Outlook 2000.
