Want to send and not to receive mail

Can I have eM Client set up only to send and not receive mail. I have two computers and I want to receive all mail in a single place

you can go to tools->accounts and for the account uncheck the ‘use this service’ checkbox for POP3 or IMAP, but keep it checked for SMTP

You can disable IMAP service in the account settings for all the accounts except the default mail account.
