Greetings, murugappan,

The first problem might be related to an invalid assigned user of either a Personal or Group Email account. Double-check if users are valid for important features like that.

The second issue is... PNG related? It's difficult to say where the root problem is, since it also might be related to the PHP version or some kind of PNG libraries. Check any of png files on your system; maybe some of them are corrupted.

In most cases, warning log messages are not affecting the system performance, but if you encounter any problem with any functionality, please describe it in more detail.

The second should have to do with the configuration of the server`s gd extension. The error tells, that interlace handling should be activated. This is necessary, so that the server can read png files, which had been saved interlaced by the image editor, that had been used to save the file. In the editor you either have the choice to save interlaced or not interlaced, or the editor by default saves in interlaced format. For both cases the sever should be able to read this format.

The first one could be caused the IMAP server returning unexpected response for some reason. I'd suggest checking email accounts (group and personal) and their specified monitored folders. Maybe some non-existent folder causes this.
