There is a bug in the email imap proxy

Hi @ll,

I'm experiencing the same issue since several releases of XG (I would say it's there for >1 year) with macOS and iOS.

The FQDN feature (and the new caching bug) was introduced in a younger release, so I don't think the IMAPS bug is directly related to this.

Thanks for your time spent to analyse this bug. This is really really annoying from time to time, while no clear errors are in the log files...

Best regards

Hi Dom,

don't give up yet. MBP has identified the potential source of the issue and is having it investigated. Looking at his answer i suspect yours will be fixed along with Shred's and mine.

I don't use SMTP very often with my private mail accounts. :-)

I noticed the SMTP problems only by doing the "Window --> Check connection" (I hope this is the correct english translation) of the macOS mail client.

Hi MBP,

my list is the same as Dom's. I think there might be a bug in  MAC Outlook because it keeps loosing the SMTP password, but this is a recent issue, since the last MS update.

For what it is worth, I have not seen any timeouts for about 12 hours which is unusual, since I put the MAC on line using my hotspot.

Dom, Shred do you have IPv6 running on your XGs?

Ian

We have open a bug ID for this. The Daemon (warren) handel all IMAP, POP3, MAPI requests seems to have a issue. Currently we try to reproduce this to get the root cause, so stay tuned. 

Hi Ian,

i'm on IPv4 only to use VPN on demand. My ISP supports IPv6 DS only right now.

Best Regards

Dom

Hi,

I have business customers affected with the same.
They are using Thunderbird and are having connection timeouts when syncing via IMAPs.

Would you be so kind to let us know when the root cause is identified and ETA for fix?

Customers are using latest 17.1 MR3 with paid licenses.

Best Regards!

Hi Tech,

I believe this issue has been fixed in v17.5 beta-2 which I am currently using. I have only been using the beta version for a couple of days and have not seen any issues with my mail other than ISP (had a major outage) ones.

Ian

Dear Ian,

I cant find any related fixes in the changelog.
Can somebody from Sophos officials confirm that this issue is addressed in the up coming v17.5?

Have a great day.

Hi Tech,

I will have to ask flosupport for an update because he was managing this issue.

Ian

Hi folks,

Thank you Flo for the update.

Flo checked the status and found the NC is still open. Interesting as to what else was fixed the might have had a flow on effect?

Ian

Any updates on this issue?

I'm having another issue that might be related:

Admin portal randomly becoming extremely slow

Just noticed today when this issue occurs (link above), the POPIMAPDaemon eventually results in a status of DEAD.

This issue is worse on 17.5.3 MR-3. Just noticed POPIMAPDaemon is DEAD again.
