JEMH on Jira 7.0.4 pull email taking very long time

[CST JIRA Confluence Admin]

Currently, we are using JIRA 7.0.4 and JEMH v1.8.41. The problem here is it takes very long time for creating a new issue. For instance: I sent an email to IMAP (port 143) mailbox at 08:00 but JIRA creates the issue at 08:40. The interval of Mail handler in Services is "Every 1 minute". Please show me how to fix this issue. I enable debug log of JEMH but it didn't have any valuable logs to investigate the root cause.

Hello,

What you describe is a well known phenomena of sending very large emails (attachments) and IMAP.  If you perform tests with 500K, 1MB, 2MB, 4MB, 8MB you'll see what I mean.

Don't use IMAP, use POP, which will download the entire email including large attachments in one hit, POP will outperform IMAP every time in this case (actually, in all cases).

Hi Andy Brook,

The size of the email is small and also it doesn't have the attachment to it. Currently, I've tried to use IMAP and IMAPS but still have the same issue. Let me try to work with POP/POPS.
