Re: That dreaded "message shrank" error

Joshua,

Thanks for the explanation. I was looking for a way to supress the
error messages in alpine, sort of like you can tell it to ignore
certificate checking on the incoming/outgoing mail server. I thought
I had seen an alpine patch that mentioned this...

I also found this info:

"The solution is on a per-user basis to use Set-CASMailbox user 
 -ImapUseProtocolDefaults:$false -ImapEnableExactRFC822Size:$true

 or on a server basis use Set-ImapSettings -EnableExactRFC822Size:$true

 Note that it will require additional overhead so I'd suggest only 
 enabling the option for people using clients that exhibit the issue. 
 Pine/Alpine is one and I've heard it reported with Thunderbird also."

Will look into fetchmail also.
