Error in TIdPOP3 component  
News Group: embarcadero.public.cppbuilder.internet.socket 

''2258440515'' is not a valid integer value" is reported for POP3 inbox when using POP3Client->List() or POP3Client->CheckMessages()

Clearly a large inbox but also a problem with TIdPOP3 component which uses 32-bit int to store message sizes. How about using 64-bit int instead as a quick workaround, it is large enough to store centuries of email?

That is what I asked: "Is your inbox 2+ GB in size?".   I guess the answer 
is yes.

I just did :)  Mailbox sizes now use Int64, but message numbers still use 
Integer for now.

I never said it has 2+ billion messages. It has 2+ billion bytes in total of these messages (which is returned by STAT).
Try using it on Hotmail (Outlook.com) or Yahoo mail - that situation can indeed easily happen if messages are accessed using POP3 and not IMAP as these 2 well known services do allow such enormous inboxes. As well as some other providers too, to avoid listing them now.

OK, but will it be fixed? It is a minor fix really.

TIdPOP3::CheckMessages() uses the STAT command, which returns the number 
of messages and the byte size of the inbox.  It is unlikely that you have 
2+ billion messages.  Is your inbox 2+ GB in size?

TIdPOP3::List() uses the LIST command, which does not return any numbers 
that List() parses, so you cannot be getting that error with List().

That is a known issue:

Update TIdPOP3 and TIdPOP3Server to support 64bit message numbers and byte 
sizes
