I having received some concerns from users that say that "some body send me an email and I did not received it" this problem is not a misspell of the email or wrongly sent. But that problem does not happen always... it seems that some times the incomming mail server queue get surendly overload, and stop receiving emails ... but I have checked the server many times and it does not appear to haeany CPU, Memory or swap overload.
Inoticed this start to be occurring with the upgrade to plesk 8.6.0
Does some body had this same problems or know how to solve it or where can I check to se if I got some clue??
Regards!
