Thank you for the relpy.
'MailspoolA' is running an older version of Courier. Upgrade both
machines to run the same version.
We assure you that they both are running on same versions(3.0.8).
However, yes, they'er running older version of Courier-IMAP.
We did not find anything related on regarding matter on release note from
ver.4.0 up to current 4.3.0. Will this problem be solved if we did in fact
upgrade both server? Considering it wasn't a problem with operating on
different versions.
If your original diagram indicates that both MailspoolA and MailspoolB are
accessing the same underlying mailboxes, then MailspoolA must be running
Courier-IMAP version 2.0, or earlier, if I reviewed the changelogs
correctly. The UIDL format you show for MailspoolA is only generated by
Courier-IMAP 2.0. Later versions report this UIDL only for existing pre-2.1
mail. But since your MailspoolB UIDLs are from Courier-IMAP 2.1+, then, as
long as both A and B are accessing the same spool, MailspoolA running
Courier-IMAP 2.0 is the only possible explanation, as far as I can see.
Updating now to 4.3.0 will make sure that you are running the exact same
version on both servers. There have been many bugs fixed since then, and the
IMAP server runs much faster now.
