I'm sorry, my numbers were wrong - 7 addresses in the list, only 5 emails received.
Here's what my list looks like (names are changed, domains are real)
myacct@gmail.com
myacct@cox.net
wifeacct@cox.net
wifeacct@rochester.rr.com
wifeacct@cox.net
myacct@cox.net
sharedacct@cox.net
I sent a test mail to that list from myacct@rochester.rr.com.
Using the file>selective mail download POP3 function I checked the inbox of each of the accounts.
Each account had 1 email that I sent, (5 total). The wifeacct@cox.net and myacct@cox.net should have had 2 emails.
Your comment about "gmail will block" prompted me to check with cox.net about their filtering. They insist they don't block duplicate incoming messages.
I also added some additional duplicate entries to the list for myacct@gmail.com and wifeacct@rochester.rr.com and resent the test email. None of the duplicate mails showed up in the inbox any of those accounts.
So, where are we? I know it's not a big issue 'cause I really shouldn't have duplicate entries in my list that would send duplicate messages anyway, but it does make me question the integrity of the process.[/quote]
You have all the tools you need to test this and satisfy yourself with what is happening: turn on session logging (Tools / Internet options - check "Create internet session logs") and check exactly what messages get sent out by Pegasus Mail to you relay server. (The logs will be in your home directory as TCPnnnn.WPM files.)
