All my outgoing Comcast emails show up as address.com in the recipients mailbox. If they use "reply", the return message is undeliverable, as it must be address.net to reach me. Is there a way of fixing this, either by having the outgoing email show .net in the address or being able to accept .com as the incoming address?
Good evening, confused_email. That sounds like both an interesting and frustration situation all at once! Are you using any third party email client at all, such as Microsoft Outlook or Windows Live?
Thanks, your question about the email server was all I needed. I am using an Android phone with whatever the default email server is. The account name was address.net, but going deeper showed it was syncing to address.com. This setup was still retrieving Xfinity emails okay, but sending them as if from address.com. I couldn't edit the phone account settings, but created a new one and deleted the old, and now the return address shows up properly.
As a side note, some "unsubscribe" functions will not accept address .net as a valid email address.
