Hi there,
I'm preparing to migrate a server (hardware's getting old). Three years
ago I've done the same thing (from 5.4.x with x < 10 to 5.4.13),
however, the contents of the server were split over two different new
servers. There were at that time some problems with migrating.
During the migration I've changed the hostname of the server, from
mail.example.com to pop1.mail.example.com and pop2.mail.example.com. I
can remember there were some problems from users by getting their mail
(through qmail-pop3d). At that time, I've changed the server's hostname
back to mail.example.com (at both servers), and every mail could be
reached smoothly again by our customers.
Nowadays both servers are still called mail.example.com. However, I
finally want to get rid of those names. So I was wondering what could
have caused these problems?
vdelivermail generates the mail's new filename, based on the hostname,
process id, timestamp and perhaps the Maildir++'s 'S=yyyy'. I was
wondering whether any of the delivery agents (such qmail-pop3d or
bincimap) makes use of the hostname to give out such mails.
Or was this maybe a misbehavior of vpopmail around those version numbers.
