Max line length exceeded when reading emails

Hello.

I am trying to automate email processing but getting the following error message

Max line length exceeded.

Please help

 

That usually happens when there are too many messages in the mailbox.

IMAP4 loop fetches message id's from the server. Too many messages may lead to buffer overload

Current buffer size is 16k, we will increase it to 1mb.

That might help but still keep an eye on the number of messages and even better only fetch unread messages

Can you try latest version please

 + Increased: IMAP4 Message list buffer
