RC Version : 0.8.4
Database : My SQL 5.2.44
IMAP Server : hMailServer - 5.3.3-B1879
No. of Mail Users : Approx. 200.
Server Capacity : Very Good, Dedicated ( Processor : 2 Nos., 32 GB Memory, RAID 5 - 8 HDD, all 15K )
I have faced this problem several times.
Just after Signed in the Mail List Pane showing all the old mails that i visited before(i.e. on last login). No new mails in the list. But once it will reach to the auto refresh time or Manually doing refresh is showing all perfect. To my experience, this is happening if the new mails are large in numbers(i.e. if i am attending too late to open my inbox let say 2 days and mails are likely more than 100), also sometimes in less number of mails let say 10 to 15.
What i am thinking/supposing, during Sign in, RCMail is entering all the new mails from IMAP into it's database and showing the same in mail box. If before committing new entries or because of some reason entry delay is there and the RCmail is taking/showing the list it may be possible. Is it because of cache ? But in my case i am not using cache.
