Sorry for not providing the full info at the beginning. I looked before mailing at the code and found it used off_t, which is 32 bit on my systems. Below are 2 setups in production; both of them have 32-bit off_t: SLES 9 / courier-imap 4.0.6 / vpopmail delivery SLES 8 / courier-imap 4.0.6 / custom delivery > > 1. The limit for a mailbox is 2 GB.

[Courier-imap] Courier IMAP and Perl Mail::IMAPClient with Proxyauth
All
I am investigating the possibility of using Perl Mail::IMAPClient to
transfer mail from a Sun JES mail system to the Courier mail system.
I have successfully used this method to connect via IMAP to a Sun JES server
and to a Microsoft Exchange server, and using PROXYAUTH transfer mail from
the Sun system to Exchange.
I was hoping to be able to do the same when going from Sun JES to Courier.
While I am able to connect as a user via Mail::IMAPClient to Courier I am
unable to get the PROXYAUTH method to work. I have tried connecting both as
"root" and "courier". If I connect as a user then I can read their mail.
An obvious question is what user I should connect as?
Has anyone done this or has anyone any suggestions? It may simply be that
this is not possible with Courier.
Some example code used for connecting to Sun JES (usernames and passwords
fudged) is below. As I mention above this works fine if I connect as a real
user but I do not have all my users passwords to enable this method to work.
Thanks in advance for any suggestions.
regards
Stephen Meatheringham

I have successfully used this method to connect via IMAP to a Sun JES server and to a Microsoft Exchange server, and using PROXYAUTH transfer mail from the Sun system to Exchange. There's no such thing as "PROXYAUTH" in IMAP. You are obviously referring to a label, or a method, used by this Perl module to implement something that's called something else, in IMAP.

I think I know what you're referring to, and Courier does not implement this optional IMAP function. pgp8Miu5l0d6y.pgp Description: PGP signature - Take Surveys. Earn Cash.

Yes, as shown in the example code I supplied. In fact, it's not even properly documented in the Perl MAIL::IMAPClient module. > I think I know what you're referring to, and Courier does not implement > this optional IMAP function. Thanks. Yes, Courier is not one of the mail servers that is listed as working with it, but then neither was Exchange. Oh well, the users will just have to save what mail they wish to keep manually, before they are moved over. Thanks Stephen - Take Surveys. Earn Cash.

[Courier-imap] poxtfix, courier chroot
Hi! I want install Postfix/Imap courier in chroot. Should I install courier inside chroot or from outsite chroot like postfix? I understand that as well I should install in chroot authlib for courier. Maybe somebody can give me some links? Regards, Krystian - Take Surveys. Earn Cash.
