Email large attachment Warning message - incorrect attachment size reported (gets larger with each send)
I have a 'standard' email which I use to send to new LinkedIn connections.
It's pretty standard text (just a few lines of text in fact), with just my html signature (very small in size) and a pdf attachment (which is 14.9MB big).
(my Hosting Server allows me to send much larger email attachments than that, I think 50-100Mb if I remember correctly).
However, four things happen when I press send;
1) I get a warning message asking me to confirm that I do indeed wish to send such a large attachment.
2) The warning message mis-reports the size of the attachment (it'll claim it to be 20.3Mb in size the very first email I send, when in fact, as mentioned above, it is only 14.9MB).
3) Then, each new email I then Choose to create via "Edit as New Message", the Warning Message appears and mis-reports again the size of the same 14.9MB attachment only this time as even larger than before, eg 25MB. This carries on for each new email being created and sent this way, with warnings of 28Mb, 35Mb etc etc attachments etc time......
4) With each new email I'm about to send, the delay between hitting Send and for that Confirmation Warning Dialog box to appear gets longer and longer until it is almost unbearably long (unworkably so)......
I have a very powerful computer, plenty of 'fastest' components, and have been a Thunderbird user from pretty much the very beginning.
Please can someone advise - as I cannot continue like this.
Many thanks.
Kindest regards,
Jez

Email encoding increases the message size by about 37%. https://www.cisco.com/c/en/us/support/docs/security/email-security-appliance/118499-qa-esa-00.html
Hi Airmail,
Fair enough, but why do they keep increasing in size, over and over, until Thunderbird is literally grinding to a halt ?
And how can I avoid this ?
Many thanks.
I'm currently waiting something like 10 minutes whilst Thunderbird gets back to me with that Warning Dialog box (and that will get worse and worse)......
I gave up after waiting something like 20 minutes for that dialog box to appear, I restarted my computer and tried sending that same message again.
I am having to wait in excess of 15 minutes whilst Thunderbird is 'not responding' to my Send request.
It looks like you are progressively re-sending the same message after it has been increased in size the first time and saved at that size in the sent folder. You hit send, it formats the message to send, the size increases by 37%, it sends and saves a copy. The copy is the larger size. Then you repeat the process by selecting the larger file to Edit as New. Now that 37% original messages gets another 37% larger.
This is my guess by looking at your file size numbers. 15 x 37% = 5.5 20.5 20.5 x 37% = 7.9 28.4 28.4 x 37% = 10.5 38.9 etc...
To avoid the cascading size increase, you could delete the attachment from the sent message, then Edit as New Message and re-attach the attachment. But if you experience long delays in sending messages that are within the size limits of your provider, and you don't think this is due to upload speed limits, then it could be due to a security/AV program scanning outgoing mail. If that feature is in place, disable it and see if it improves performance (it should be disabled anyway).
