Between Wednesday, April 21 at 9:30am EST and Thursday, April 22 at 8:35am, I have confirmed that at least four of the eight emails I sent using my domain's SMTP (mainecove.com) went undelivered. One was an AOL domain, but three others were mail servers for small businesses.
Was there an unreported outage, or was our mail server (server 17) added to a blacklist? The other four other emails that I have not confirmed were to potential clients, so I resent the emails today, but I am still displeased about the situation.
Please let me know if you know anything.
