Using YahooPops POP3 proxy (
to retrieve messages from free Yahoo account.
Works fine for a few messages (3-5).
With more messages (14), Mozilla generates the following error
after receiving first message:

Unable to write the email to the mailbox.
Make sure the file system allows you write privileges,
and you have enough disk space to copy the mailbox.

YahooPops is slow.
I suspect this is a timeout problem.

Outlook Express has user-settable timeout.
It must be set to the max (5 min) to work well with YahooPops.

Mozilla does not seem to have a user-settable timeout for POP3.
Can a user-settable POP3 timeout be added to Mozilla Mail ?

Reproducible: Always

Steps to Reproduce:
1. Send several messages to Yahoo account.
2. Setup Yahoo account in Mozilla, using YahooPops (localhost, port 1100).
3. Attempt to retrieve messages from the account. 

Actual Results:  
When more than X messages,
Error message after 1st message is retrieved.

Expected Results:  
All messages retrieved with no errors.

Communications between YahooPops and Mozilla

YahooPops logs into Yahoo, gets info about messages.
Mozilla: STAT
YahooPops: +OK x yyyy (x = number of messages)
Mozilla: LIST
YahooPops: 1 1875 (etc. for all messages)
Mozilla: UIDL
YahooPops: 1 zzzzz (etc. for all messages)
Mozilla: XSENDER 1  (only when there are enough messages to cause error)
Mozilla: RETR 1

I've just tested Mozilla and YahooPOPs without any problem. Retrieving of 14
Messages was done within a minute.

YahooPOPs works that way in parsing and downloading all messages (resp. up to
the maximum you defined). In this time Mozilla waits for YahooPOPs is sending
the messages. But once that has started it's done without any wait between the
messages from STAT to QUIT.

Because of this and the error message I doubt it's and timeout issue. But I've
no idea why you get the error only if you have more messages to retrieve.
