Question

I have been using contact form 7 to send and receive emails in word-press, every thing was working fine. but suddenly it stopped working at all. problem statement is as bellow

1. i am using gmail services to send and receive emails for example info@mydomain.com

2. contact form 7 (in word press) plugin is being used for sending and receiving emails on website that i am working on.

3. suddenly hosting server(big rock) closes the port 80 as it reported spamming from website due to virus infection in files.

4. c panel virus scanner showed every thing clean after replacing the infected files and port 80 got opened once again. but still unable to send and receive emails, however it displays success message after submitting the form
