Methods

SendCentrum(int, From, string, MailMessage)

Sends email via Centrum.cz SMTP server. Note: Centrum now requires SMS verification code for each email sent via SMTP, making this method impractical for automated sending. After one email succeeds, subsequent emails will be blocked.

public bool SendCentrum(int attempts, From from, string to, MailMessage mailMessage)

Parameters

attempts int

Number of send attempts to make before giving up.

from From

Sender credentials (name, email, password).

to string

Recipient email address.

mailMessage MailMessage

Pre-configured mail message to send.

Returns

bool

True if email was sent successfully, false otherwise.

SendSeznam(int, From, string, MailMessage)

Sends email via Seznam.cz SMTP server. Note: This method may timeout at smtpClient.Send with "The operation has timed out." Consider using Seznam Email Pro for better reliability. Alternatively, try using a desktop email client to verify SMTP settings.

public bool SendSeznam(int attempts, From from, string to, MailMessage mailMessage)

Parameters

attempts int

Number of send attempts to make before giving up.

from From

Sender credentials (name, email, password).

to string

Recipient email address.

mailMessage MailMessage

Pre-configured mail message to send.

Returns

bool

True if email was sent successfully, false otherwise.
