[pkg-fetchmail-maint] Bug#314509: fetchmail: IMAP timeouts & wrong message counting

[Stepan Golosunov]

Package: fetchmail
Version: 6.2.5-12sarge1
Followup-For: Bug #314509

I have seen this bug several times. To reproduce it I sent 20 messages with
$ for ((i=1;i<=20;++i)); do mail -s "Test#$i" stepan at golosunov.pp.ru < /dev/null ; done
Then while fetching these messages I started
$ for ((i=1;i<=10;++i)); do mail -s "Test#X$i" stepan at golosunov.pp.ru < /dev/null ; done
I have got wrong message message count (17 messages per minute is too
high for me) and timeout after fetching 10 Test#X messages (f21.log).
On the next run I have got only 2 messages (f22.log).

None of test messages were lost.

I have also reproduced this bug using dovecot-imapd as a server (within
qemu). In this case timeout comes before fetching additional messages
and they are fetched later; some messages have X-IMAPbase: header and
once I have seen ")" (#312415?) in the message body (generated from /dev/null).
