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.

Ian

Nobody of you is using a "Paid" appliance isn´t it? 

Because would be much easier to have a support case :) 

Hi MBP,

Shred and I are both home users, I think Dom is a business customer and might be able to help?

Ian

Nope, I'm just a Home user, too. :-(

No Problem.

Can you tell the firmware this issue was first time seen? 

Mail totally broken this morning, no sending or receiving. Need password which cannot be authenticated to not saved.

I can rebuild this XG using the latest ISO if you think that will help with the debugging.

Ian

Just found it is an ISP (RSP) issue (today's issue). Back to sleep in the corner. Fails via XG, but works via hotspot. Anyway ISP website advises it is their fault today.

I rebuild everything with Windows 10 - Thunderbird - XG V17.1 MR2 and a Gmail Account.

Can you tell me, when this happen in your env? Only by getting new mails or also by just fetching for new mails but there are no new mails? 

I need more details about this issue to reproduce it. 

Hi MBP,

usually happens when the automatic retrieval process runs. Sometimes if I manually initiate a get mail it will timeout.

Update, I have added my mail accounts back, so I now have 3 mail accounts from 2 different ISPs.

Just before I started to answer your question one account was asking for a password, ignored all the requests and the account is now working.

My wife's MAC outlook is broken, asking for passwords and showing errors, her MAC mail is working fine.

Ian

Te stupid part about the error is that the mail is up today even when showing the timeout error.

Do you need access to my XG to explore?

Can you tell me something about the "history" of this appliance? 

Which Firmware did you use to install? Did you update the Version X to V17.1?

Currently all my tests works fine. My home appliance seems to work also fine. 

Hi MBP,

this one was rebuilt using 17.0.8 and the auto update installed v17.1.2 during the configuration.

I rebuilt it because I thought I had damaged a data file because an application does not appear in the drop list. After the rebuild I still had the same issue.

Hi rfcat_vk Dom Nik  shred 

Can you shortly give me following information:

Outlook version affected.

Since which Firmware appeared this issue? 

Mail Programm affected (with Version). 

Hi ManBearPig,

I'm experiencing the issue with:

- Apple macOS 10.13 High Sierra - Standard Mail Client

- Apple macOS 10.14 Mojave - Standard Mail Client

- Apple iOS 11 - Standard Mail Client

- Apple iOS 12 - Standard Mail Client

Protocols:

- IMAPS Port 993

- SMTPS Port 587

XG Versions:

- I don't know exactly but I'm sure the problem appears sporadic at least since one year

- My XG KVM image was build in February 2017 with the newest image available that time and a Backup-Restore configuration

- I keep my XG always up to date (max. gap after new release should be 1 week :-) )

- Please let me know if there are log files of my upgrade history to provide you some more details

I hope this will help you a bit.

Best Regards

Dom Nik

My info is identical to Dom Nik. The issue for me is only with IMAP/S. SMTP works fine.

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.
