All,
� Since my crappy ISP started blocking mail from opensuse to my suddenlinkmail.com account I have had to switch my account to gmail. The problem is I never see the mails I send, not my original post or my replies to the list.

That's a feature. WONTFIX :-P I have a solution that WFM, but it's relatively complicated. Several years ago, I switched to Gmail from running my own MX for rgrjr.com, since it just got to be too complicated to maintain my own mail exchanger. Outgoing emails go through Google servers, and incoming emails are forwarded to my home system through a VPS that is still named rgrjr.com, which is necessary to work around my ISP's embargo of port 25. (Linode.com offers openSUSE VPS nodes for as little as $5/mo.) But I also didn't like the way they handled lists, so I now subscribe to lists with a separate domain (rogers-suse@rgrjr.homedns.org in this case), having set up the MX for rgrjr.homedns.org to point to rgrjr.com to avoid the aforementioned port 25 embargo. and have a delivery script that puts openSUSE email into its own Qmail-style incoming folder. (And can also eliminate duplicates, on request.) Gmail intentionally deletes duplicate emails, and it detects them by checking the Message-ID header . . . There is a well-known timing flaw in SMTP that can potentially result in duplicate copies being delivered, so they probably feel that silently swallowing duplicates avoids annoying users in the other direction. -- Bob Rogers http://www.rgrjr.com/
