Mailshield and Gyazmail

I am new around here, so please bear with my stumbling around. I’m so new, I misplaced this message on the PC forums yesterday.

I am on an “ancient” macbook that can only use OS X 10.7.5 and I started using Avast to give another layer of security on a machine that no longer gets security updates. As I continue to use this machine, I am staying on the linux partition more and more, but there are programs I need on the Mac side.

The email program I have been using for many years is a relatively obscure one out of Japan, Gyazmail, that is built via Cocoa for the Mac, and has nearly all the features I need in an email client. (There are things about Apple’s native Mail that I cannot abide, and Thunderbird is too clunky. Other likely clients have moved on from my platform.)

Since using Avast!, I have run into a peculiar problem. Of the three accounts collected on my email client, the primary one offers up a complaint when attempting to download from the server:

“Gyazmail: error occurred while receiving messages.
POP protocol error: -ERR Mate, the command must be one of CPRA, USER, PASS or Quit.”

The other two accounts, on IMAP, the other POP, have no complaints.

When I disable the email shield in Avast!, the complaint stops.

Does anyone have a clue why this error occurs?

Thanks!

What is the POP3 server of the “broken” account?

Thanks for your reply, tumic.

If you mean my incoming mail server for the specific account, it is

mail.cruzio.com” set to STARTTLS and to verify the certificate.
