LL 3.6 64 bit 4GB RAM
Been using Thunderbird for mail for 6years+ on Windows and now LL since 2014. been very reliable - updated etc. via LL updates.
Now and again started to get the following come up when sending emails.
"Your message was sent but a copy was not placed in your sent folder (Sent Items) due to network or file access errors. You can retry or save the message locally to Local Folders/Sent
Items-xxx@yyyy
.eu.
Your message has been sent and saved, but there was an error while running message filters on it"
Copies of emails fail to appear in sent folder for that email address although I press yes to save if that message comes up on screen.
Also if I use browser to view sent emails (webmail) the corresponding email fails to appear, BUT recipients tell me they have received them???
I have checked both Thunderbird and my ISP and separate Mail host and have no filters set on any of them - blanks
Seems to happen if I have attachments to emails (Few MB) such as pdfs or jpgs.
Running SOPHOS in background - Not aware that there are filters there that could be interfering- would not know where to look. No SOPHOS warnings in log
Stared BCC emails to a back up gmail account just to be sure.
The trouble is that this does not happen all the time, just now and again. I have checked capacity on my email host server and I am about 60% of my allowable capacity.
Hope the above makes sense. Ideas / check routine welcomed.
