POP3 and IMAP problem for one user

Question

Hi All,
One of my users has recently connected her iPhone4 to our GW7. We set her up just like numerous other of our users, and she is having some issues. When set up as IMAP using the default application on her iPhone, she can see all her folders and all her mail up to December 21, 2011, but nothing after that. If she asks to download more messages, it successfully shows earlier messages, but still nothing more recent than December. When set up as POP, she is able to download recent messages, but there are wide gaps in what she can see. Whole days are missing. I can send her a new message, and she can POP it right away, but messages that came in just hours before will not come over. None of our other users have any such issues--including at least one with the same iPhone.
The user swears that she has no other e-mail program POPing mail--and even if she did, I don't think it would explain the IMAP issue--but I may be wrong about that. This user does have an incredibly large online mail account--over 20,000 messages in her Mailbox folder alone. I have examined her POA indexes, and they show nothing un-indexed.
I have used my own phone (Droid Bionic) to connect to her GWise account and I see the same behavior from her account.
We are using GWIA 7.0.2, and I can see her phone making connections successfully. I see no errors, but I have not yet studied a Verbose display when she connects.
Any suggestions about how to proceed to troubleshoot this?
What could I do if I wanted to reset whatever information her account stores as to what messages have been POP'ed off or to reset whatever info about IMAP is maintained?
Thanks in advance,
Peter.

My understanding is as you raise it, the memory usage of the POA and the
CPU hit on the POA will increase. It's been explained to me that the
IMAP standard requires certain correlations and bufferings to made
between the different items, so the memory usage increases. (IMAP is
fairly complex, so I doubt I can explain it all since I doubt I
understand it all). For example IMAP requires synthetic UIDS to be
correct for all the items in the mailbox during the session. There is
room for improvement here, but it hasn't been a super-high priority is
what I was told just this past BrainShare. It will never be a completely
low memory "streaming" kind of solution though - a lot of state has to
be built and maintained during the IMAP session.
POP, I'm not sure about. I do know GW can get confused. Have her specify
her pop UserID differently. For example if her normal gwmailbox is
jsmith, have her try jsmith:v=2 .
Also see other whacky POP switches
you can set affect the date range, and #. The "v","l",and "t" are the
most important.
User ID Login Options
With POP3 clients, users can add the options listed in the table below
to the login name (GroupWise user ID) to control management of their
mailbox messages. If used, these options override the POP3 settings
assigned through the user’s class of service (see Section 47.1.2,
Creating a Class of Service).
Login options are appended to the user ID name with a colon character
(:) between the user ID name and the switches:
Syntax: user_ID:switch
Example: User1:v=1
You can combine options by stringing them together after the user ID and
the colon without any spaces between the options:
Syntax: user_ID:switch1switch2
Example: User1:v=1sdl=10
The syntax for the user ID options is not case sensitive. Login options
are not required. If you do not want to include any login options, just
enter the user ID name in the text box, or following the USER command if
you are using a Telnet application as your POP3 client.
Table 46-1 User ID Login Options
Option
Explanation
Example
v=number between 1-31
The v option defines the POP3 client’s view number. If multiple POP3
clients access the same GroupWise mailbox, each client must use a
different view number in order to see a fresh mailbox.
For example, if two POP3 clients access a mailbox and the first client
downloads the unread messages, the second client cannot download the
messages unless it is using a different view number than the first client.
If this option is not used, the default value is 1.
User_ID:v=1
d
The d option deletes the messages from the GroupWise mailbox after they
have been downloaded to the POP3 client.
User_ID:d
p
The p option purges the messages from the GroupWise mailbox after they
have been downloaded to the POP3 client.
User_ID:p
t=1-1000
The t option defines the download period, starting with the current day.
For example, if you specify 14, then only messages that are 14 days old
or newer are downloaded. If this option is not used, the default value
is 30 days.
User_ID:t=14
n
The n option downloads messages in RFC-822 format rather than the
default MIME format.
User_ID:N
m
The m option downloads messages in MIME format. This is the default.
User_ID:M
s
The s option presets the file size when the STAT command is executed. If
the user mailbox contains a lot of messages or large messages, it can
take a long time to calculate the file size. With this option, the STAT
command always reports an artificial file size of 1, which can save time.
User_ID:S
l=1-1000
The l option limits the number of messages to download for each POP3
session. For example, if you want to limit the number of messages to 10,
you enter l=10. If this option is not used, the default value is 100
messages.
