I'm using Thunderbird under Ubuntu Hardy Heron. I set up my IMAP account using the Idle feature and everything works fine except for resuming from Suspend to RAM.
After resuming from S3, Thunderbird doesn't report new mails anymore and even manually checking for new mails fails as well as downloading the content of already fetched headers. I have to quit Thunderbird and restart it to get it in a working state again.
Steps to Reproduce:
1. Open Thunderbird with IMAP Idle enabled
2. Suspend to RAM
Thunderbird doesn't report new mails and even worse is unable to manually check for new mails.
Thunderbird reestablishes the connection to the IMAP server and reports new mails.
Similar situation is reported to Bug 425897 for Tb trunk on MS Win Vista.
Can "offline.autoDetect" to false be a workaround?
How long is the suspend time? If DHCP is used for client PC's IP address assignment, and if IP address assignment by DHCP expires during suspend, similar phenomenon can occur on Tb (AFAIR, already opened bug). Is this case?
Anyway, get NSPR log and check real protocol level flow first.
See Bug 402793 Comment #1 for getting NSPR log.
Following will probably be required for your intial analysis.

NSPR log with S3 and resume
I'm using a DSL connection with dynamic IPs, so most likely the IP will change after every resume.
I tried to get the NSPR log, although I'm not sure if I did the right things. Ubuntu's shell doesn't feature setenv, so I used the following instead:
> export NSPR_LOG_FILE=NSPR-Log
> export NSPR_LOG_MODULES=imap:5,nsSocketTransport:5,nsHostResolver:5
After that I started Thunderbird which automatically connected to my IMAP account, went to S3, resumed from S3 and tried to manually check for new mails. After that I quit Thunderbird.
I hope there is no sensible information in this huge log, especially no passwords?
This could be same issue as Bug 468490
no we don't reconnect if the server drops the connection while idle. But the normal check for new mail at the normal interval (I think the default is 10 minutes) will cause a reconnect, and then we'll go idle for as long as the server doesn't drop the connection.
