Using SMTP can encounter difficulties when one is not connected to the
system for which the server provides service. There are several ways which
ISPs use to curb spam abuse of their servers, some of which can hamper what
you intend to do.
If either of your ISPs offers an SMTP server with SMTP AUTH capability, that
will be a help; as long as the other service does not block port 25
outbound. You would just set your travelling identity to access the server
with the SMTP AUTH capability, properly configured, and you will send email
from anywhere that the Internet reaches.
Look in Tools > Accounts > Properties, on the server tab, "Outgoing Mail
Server" section, and check "My server requires authentication". Please do
keep in mind that this does require that the server recognize SMTP AUTH
commands. Just checking the option on any server won't make it happen, if
that server doesn't understand the commands.
I suppose I could get even more detailed if I knew which ISPs were involved,
and the server names you use. In general, if you can run Telnet, you can
attempt to access the SMTP serve on port 25 from Telnet. Issue a 'HELP' as
an input and you usually get a list of available SMTP commands. It will look
something like this:
220 comcast.net - Maillennium ESMTP/MULTIBOX rwcrmhc13 #15
HELP
214-Commands:
214- 7BIT DSN MAIL RSET XTND
214- 8BITMIME ETRN NOOP SIZE
214- AUTH EXPN PIPELINING STARTTLS
214- BDAT EHLO QUIT VERBOSE
214- DATA HELO RCPT VERS
214- DELIVERBY HELP RFCS VRFY
214 For more help type 'HELP command'
QUIT
221 comcast.net
Note in the first column, fourth line beginning with '214', the command
'AUTH' is available to Comcast users. Not all SMTP servers respond with a
command list, though:
220 smtp801.mail.sc5.yahoo.com ESMTP
HELP
214 qmail home page: http://pobox.com/~djb/qmail.html
QUIT
221 smtp801.mail.sc5.yahoo.com
SBC Yahoo! wants you to go to a web site for commands. It looks like they
use a mail server called, 'qmail', and expect you to get the command list
from that site.
Of course, if your SMTP sever does offer a command list, and 'AUTH' is not
on it, there are other steps one can take. If that isn't very clear, post
back to this thread with both of your ISP server names; we can take it from
there.
