We are on our new dedicated server, I setup email id on my Mac and it works fine from the office but when i use the same Mac laptop in my home and check email it doesnt work. Account goes offline in home.
please remeber in office we have different ISP and in home i have different ISP.
Plus sometimes when i send emails with attachments to an address it goes fine and deliver too to the destination address but the desination user only can download the email but cannot download the attachemnts from my email id and when i checked online in my Roundcube , Horde or Squier mail box in my sent items the attachment is there but not delivered to the user whom i sent the email?
What could be issue, as i am handling this email system for my office
Note: We are using Devocotmail settings should i select Courier and select courier will effect the email users or email settings like sending or receiving protocols?
