I'm having an issue where qmail is unable to send to certain domains, leaving them in the queue for about a week before returning the messages with this mailer-daemon error:
Connected to xxx.xxx.xxx.xxx but connection died. (#4.4.2)
I'm not going to try again; this message has been in the queue too long.
95% of my messages send out just fine, right now it's only about 5 domains that I cannot send to, but the list seems to be slowly growing.
Here's my server info:
" Media Temple (dv) server
" Plesk server software
" I use a shared IP with about 25 of my clients
After doing a lot of research on this, the only answer that I've come across is that my domain (or IP) is on a blacklist. I've used quite a few tools to find out if this is the case, but thus far I'm not on any lists...
I've resorted to using my gmail account to send mail to these certain domains, but unless I check the mail queue every time I send a message (not practical) it takes a week for the me know if someone received the message...
Thanks in advance,
