Hi,

I have finished setting up Afterlogic webmail lite PHP version 7.1.1.1 successfully.
Everything work fine except the attachment size.
I have AttachmentSizeLimit and ImageUploadSizeLimit = 20480000, I also have php.ini set post_max_size = 50M & upload_max_filesize = 25M.

However based on test that I've done the limit is currently 15M. The error doesn't prompt during upload but when I click "Send":
"an error occured during sending the message."

Anything else I missing?

Other than that, I remember in previous version we can have the attach button to be changed to HTML-based instead of current flash-based.Is this still available? I can't seem able to find webmail.php which mentioned on other post.

Lastly, some old PC not able to use the tick box. Nothing happen when they click it. Any idea it related to IE setting or version?

Thanks in advance!

Sounds like file upload isn't a problem, then. I'd recommend to enable logging in AdminPanel, replicate the problem and see what's in the log file. Most likely, you're going to see the error message returned by SMTP server. SMTP servers often have a limit on size of messages they can accept for delivery, that might be a reason here.

That approach is no longer supported.

That might be related to specific browser version indeed, we'd need to know which version is used. Current version of AfterLogic WebMail isn't guaranteed to work on IE versions lower than 8.

Hi Igor,

Thanks for your responsive reply! It's a great experience on your support.

You replied before I found the root cause. Yes I've enabled the logging and found the size limitation is from my mail engine itself.
However I am surprise because the attachment I sent is only 19.5MB (showed on web) and the log show the whole mail is 27MB, which means the message body added 7MB in the size. My mail engine has a limit of 25MB that's why it still not going through, which made me think it's the limit of webmail.

I see. OK.

I'm on IE version 8.0.6001.18702. I will try upgrading it to see whether this can be solved.

Again, thank you very much.

When you send files as attachments, they're encoded with base64 algorythm to make sure whatever the content is it can be transferred and received properly. The downside is that size is increased by about 30%. That's not something specific to AfterLogic WebMail, pretty much any email client does that kind of encoding/decoding when handling attachments.
