I've been able to get IMAP to work all be it in most cases without SSL, as it's pretty finicky, but there is one email host that I"m trying to connect to via imap and it's just not connecting to pull the folders, or the email any more. in the logs it's showing the following error.
[Wed Mar 15 19:54:09.440182 2017] [:error] [pid 59823] [client 192.168.1.1:58851] PHP Fatal error: Maximum execution time of 300 seconds exceeded in /var/www/html/aiemmoffice/library/PEAR/Net/IMAPProtocol.php on line 3760, referer: hXXp://XXX.XX.XXX.XXX/aiemmoffice/index.php?c=access&a=index
and getting an error 500 across Feng. I'm running version 18.104.22.168. Any assistance troubleshooting would be appreciated.
