Bug report

Title

Email with a password that have special characters like @.!? will be not able to send email in UVdesk.
The bad thing is that no error is showed when admin save the settings.

The error will occur only if a ticket is created or a notification need to be sent by email, no email will be sent.

Please add the support for special characters in email passwords!
If this is already supported for IMAP incoming add support also for SMTP settings!

I'm asking why you don't do any check when save email credentials.
Usually application check if they are able to connect to IMAP or SMTP and if something is wrong an error message is showed.

UVdesk never do any of this check, just save email settings, showing a green message even if credentials are wrong. This is bad.

Also UVdesk is the only app I know that create issues if special characters are in the password.

I hope you can fix this two things:
add check on SwiftMailer and MailBox

And allow special password character that if is present now will broke UVdesk as email stop to work.
