Send Fails

I’m getting repeated failures on send (via charter.net SMTP). The failed item has an attachment 6.197 KB. It is addressed bcc to about 20 recipients. All sends without an attachment go through no problem. The attachment is a slide show of the history of building the Statue of Liberty, its’ maintenance over the years, the renovations not long ago, etc. There is no content in the body of the message nor in the slideshow that should cause this send to fail. I contacted Charter and ran online tests via their SMTP server - no problems on simple messages, and they don’t have a barrier this small on message size or header content. Any idea why this message repeatedly fails?

This may be caused by a firewall or antivirus. Send us your logs please: go to menu Tools->Settings->Logging and check “SMTP” under the problematic account. Then restart eM Client, try to simulate the issue and send us (with reference to this topic) the logs using the same logging settings window. Thank you.
